Lumb steps away to leg to make some room but his cut goes in the air and Dwayne Bravo is able to take the catch above his head at backward point. Rampaul gets the breakthrough in his first over back. Lumb faced 117 balls, including seven fours and two sixes.
Lumb eyes up the leg-side against Dwayne Bravo and twice lofts over the in-field but short of the boundary. Will West Indies bring Narine back on in this situation, he's still got five overs left.
England are taking the batting power play (because they have to). Only three fielders allowed outside the circle for the next five overs. Will be interesting to see how both sides approach this.
Lumb's century celebration was quite subdued by modern standards, just a raise of the bat as he ran through for the single and a quick acknowledgement of the applause after removing his helmet for the photographers. England need 99 from the last 15 overs, that's a required-rate of 6.60.
Lumb gets to his landmark with a couple of singles, including a lengthy wait on 99 while bowler Sammy receives treatment for what appears to be a chest muscle problem. It makes no difference, Lumb gets one into the covers to complete a 109-ball century (7x4 2x6) and become the ninth batsman - and second Englishman after Dennis Amiss - to score a hundred on ODI debut.
Dwayne Bravo continues after drinks and Lumb inches a run closer to his century thanks to a quick single to square-leg. Root also picks off some easy runs into the leg-side, three in total.
Root is lucky as a leading edge drops safely on the off-side. He was aiming at midwicket but turned the bat too early. Just a couple of singles from Sammy's over and it's time for drinks with England needing 107 off the final 17 overs.
Dwayne Bravo comes back for another spell, West Indies must be regretting the lack of a second spin option on this pitch. After an early exchange of singles there is the first sign of the 'nervous 90s' for Lumb as he flirts and misses a slower ball outside off-stump.
Scoring a hundred on ODI debut is quite a rare feat, there have only been eight in all, including Andy Flower for Zimbabwe and, most recently, Australia's Phil Hughes.
Lumb is peppering the boundary behind square on the off-side, easing another four down to third-man as Smith continues to toil away. A couple of singles later in the over move the Notts left-hander to 90. Dennis Amiss is the only England batsman to have made a hundred on his ODI debut...
The runs coming thick and fast again as Sammy is punished for dropping too short. Lumb collects a pair of twos and then cuts for his sixth four (plus two sixes) to move into the 80s.
The first boundary in eight overs as Lumb takes advantage of some width from Smith to cut away for four. Was in the air for a while.
Root has upped the tempo with the running between the wickets since his arrival at the crease. It's Lumb who mainly benefits from his partner's hustle in Sammy's over with a pair of twos among a total of seven runs.
Same again, three singles off Smith's over, all into the leg-side.
Ones and twos again the order of the day for England's batsmen against Sammy. Sensible batting, no risk involved and the required-rate is well under control.
Root got an unbeaten century on this ground on Tuesday in England's warm-up victory over the UWI VP XI, his first three-figure score of the winter after a difficult time of it in Australia (although that could be said of all England's players except Broad and Stokes). Three singles in Smith's over as England take their time to regroup after those two wickets.
Root joins Lumb in the middle and opens his account with a quick drop-and-run single to mid-on from the final delivery of Sammy's over. England need 163 off 162 balls.
Wright pulls straight to Dwayne Bravo at midwicket to end a tortured nine-ball stay. The less said about that innings the better.
Wright finally gets off the mark to his eighth ball faced but it's far from convincing, a top-edged pull falling safely between three fielders. Smith, the bowler, left shaking his head at that.
Lumb drives down the ground for a single from Sammy's first ball and Wright - who played and missed at his first delivery in the previous over - spends the next five balls poking around to no great effect.
Prior to Moeen's exit, Lumb brought up his maiden ODI half-century (58b, 3x4 2x6) with a single cut to third-man. He's the 20th Englishman to reach 50 on his ODI debut.
Medium pacer Smith strikes with his third ball, Moeen lifting a catch to Narine at long-off. He didn't try and hit it hard but timed it too well if anything. It was a straightforward catch for Narine moving in and to his left on the boundary. Moeen's departure ends an opening stand of 96 in 19.3 overs and brings Wright to the crease.
Plenty of singles available against Sammy. Lumb moves to the brink of a half-century and keeps the strike with one towards midwicket from the final ball.
Moeen is trying to play Narine off the pitch but it's not giving him much time to react. Three singles in the over, Moeen driving the final ball into the covers to retain the strike.
Another medium pacer, Sammy, into the attack after drinks. No sign of a breakthrough in that over, Moeen turning one into two with some hard running.
Moeen pokes and misses at the final ball of Narine's over, he stayed back to give himself some extra time but still had no idea what that delivery was going to do.
Dropped! Moeen living dangerously in the last couple of overs. Smith fails to cling on to a one-handed chance diving to his left at backward point after the left-hander drove a wide ball from Dwayne Bravo hard, but in the air. Tough chance, Smith almost pulled it in though.
Moeen enjoys a moment of fortune, advancing to Narine and following through with a drive that goes high in the air and drops just out of mid-off's reach as he ran back.
Dwayne Bravo mixes up his during an over that is going well until he drops the final ball in short to Lumb, who lifts it off his chest for four to third-man. Delicate touch.
Most of Narine's variations come out the front of his hand, although he also bowls a more orthodox off-spinner on occasion. Moeen and Lumb not really picking what's coming down but they muddle their way through without undue problems, picking up five runs - three singles and a two - along the way. Narine's not a big turner of the ball, it's the bounce he generates that causes problems.
Dwayne Bravo decides it's time to take matters into his own hands and brings himself on to bowl. The early signs aren't promising for the West Indies skipper, Lumb upper cutting a short ball for six. It landed right on top of the rope.
Umpire Brathwaite reverses his decision for the second time today. He gave Lumb out lbw but the batsman immediately signalled for a review and replays show why, there was a big inside edge into his pad. Rampaul responds by hitting Lumb in a delicate area with a delivery that bounced less than expected.
Narine has a slip and gully in position. Lumb and Moeen happy to work the singles around until the final delivery, which is slog-swept for three by Moeen. He was hitting into the breeze and it stopped just short of the rope. Perfectly safe shot with no fielder back at midwicket.
Lumb targets the leg-side against Rampaul and collects back-to-back fours, the first pulled off the front foot and the second whipped from middle stump just short of the rope. Lumb keeps the strike with a driven single. Both of England's ODI debutants have settled in straight away. Off-spinner Sunil Narine is coming into the attack...
Lumb finds the middle of his bat for the first time, drilling a length delivery from Holder over long-on for six. Lumb cuts in the air, safely enough, for a single and Moeen adds two from the final ball via an under-edged pull.
Lumb risks a single to short fine-leg, would have been tight with a direct hit. Moeen again flashes and misses outside off-stump as Rampaul pitches it full to tempt him.
Moeen has a very elegant style, driving and pulling Holder for consecutive fours and then driving through mid-on for three to get off strike, all three strokes performed with a high backlift and full follow-through. Lumb drives square for a single to keep the strike.
Moeen appears keen to go after anything outside off-stump from Rampaul, swishing once at fresh air before finding the middle of the bat with a cover drive that races away four.
Moeen spars at and is beaten by a Holder delivery that cut away from his off the seam. The Worcestershire left-hander rotates the strike later in the over with a flowing drive into the covers for a single. Lumb, also a left-hander, punches down the ground for two from the final ball.
Ravi Rampaul shares the new ball. Lumb again turns over the strike with another drive into the covers and Moeen opens his account in international cricket by running the first ball faced down to third-man for a single.
West Indies don't wait long to waste their one and only review of the innings, sending an lbw shout against the left-handed Lumb from Jason Holder's third delivery upstairs. Height (Holder is 6ft 7in) always appeared to be an issue and replays show it was comfortably clearing the stumps. Holder gets England going with a wide and Lumb drives the final delivery through the covers for a single to keep the strike.
Lumb and Moeen are England's opening pair today, both making their ODI debuts today.
Nice moment during the interval as three West Indian cricketers of days gone by, Andy Roberts, Richie Richardson and Curtly Ambrose, received their knighthoods. It will be Sir Andy, Sir Richie and Sir Curtly from now on.
Hard to judge how good a total that is for West Indies but they're certainly in the game, which didn't look likely after those four early wickets. Lendl Simmons and Dwayne Bravo put together a sedate repair act before the batting power play, taken as late as possible in overs 36-40, prompted West Indies to launch their attack and Sammy added the cherry on top with those late sixes. 157 runs came off the final 15 overs to set up an interesting run chase for England.
Sammy departs to the final ball of Bresnan's closing over but his 36-ball innings has breathed new life into this game. Bravo finishes unbeaten on 87 from 91 deliveries, he oversaw the recovery and then went on the attack alongside the more agricultural Sammy as 85 runs came from the final five overs.
Sammy brings up his seventh ODI half-century (34b, 4x4 4x6) and first against England with six back over Bresnan's head. The next one disappears for four through backward point before he finally falls to the last ball of the innings, holing out to Broad in the covers.
Jordan takes the penultimate over. Dwayne Bravo gives himself some room to loft the first ball for four over extra cover off the back foot. Sammy swings hard and edges over wicketkeeper Buttler for four more. Jordan over-steps and Dwayne Bravo leans back to cut for six to backward point. Free hit to come... Jordan jams in the yorker and Dwayne Bravo can't do anything with it. Dwayne Bravo lifts the final ball of the over to third-man for four, incredible shot, played it off his chest as he fell backwards. The average first-innings score in ODIs at this ground is 245, Thanks to 21 runs from that over, West Indies are now officially above-par with six balls still to come.
Bresnan continues, the batsmen are hitting into the leg-side with the wind from this end. Dwayne Bravo carves an edged drive to the boundary and is then fortunate when a heave into the leg-side falls just out of the reach of a diving Tredwell. England are on the run in the field now, failing to prevent Dwayne Bravo coming back for three after Sammy's latest swipe pulls up short of the rope.
Root's bowling gets taken apart to the tune of 23 runs (his previous eight overs cost 24 in total). Dwayne Bravo completes a half-century stand with Sammy from 39 balls by sweeping the first delivery for four. Sammy then takes charge, slamming consecutive sixes down the ground, the first after a shimmy down the track, the second from a bottom-handed smear after stepping back. Sammy needs a visit from the physio after tweaking his groin when diving to make his ground after a quick two but he's fine, cutting the final ball of the over for four.
Bresnan is the latest seamer to get a chance from this end. Wright and Moeen converge on a skier from Dwayne Bravo but, despite the fact it hung in the air for an age, neither can get under it. Dwayne Bravo pulls a short ball from outside off-stump for a one-bounce four to square-leg. Bresnan also gets into wide trouble with umpire Marais Erasmus, going too far outside off-stump as the batsman moves across. Sammy inside edges a big heave past his leg-stump and away for four to finish the over, taking West Indies to 200 in the process.
Dwayne Bravo completes a 74-ball half-century (3x4), his 10th in ODIs, with a couple towards midwicket. Root again races through his over with limited damage, five runs from the over.
Jordan is back on for another go and surprises Sammy with a sharp bouncer. Jordan only ambles up to the crease but he's sharp. Sammy aims at midwicket and eventually gets hold of one, sending it all the way for six. Three wides in a row - all too far outside Sammy's off-stump - takes Jordan's tally to eight in as many overs.
Root fires it in at Sammy's pads from round-the-wicket and escapes with just a single from the over, Sammy keeping the strike with a prod into the leg-side.
Switch of ends for Broad. Dwayne Bravo doesn't pick a slower ball and is fortunate his aerial drive falls safely in the covers. Sammy shoulders arms and is hit on the pads and - incredibly - Broad barely even considers using up England's review before marching back to his mark to get on with things. The captaincy mist be having a strange effect on him.. Sammy swats the next one to the midwicket boundary (a real smear, he's scored a 20-ball half-century on this ground and it's not difficult to work out how). Dwayne Bravo clips a leg-stump offering to the boundary to complete an expensive over for England, 10 runs from it.
With the fielding restrictions again relaxed, Broad goes straight back to spin in the form of Root. More good fielding from England saves a couple of runs, including a rocket-arm return from Bresnan after a sliding stop down at third-man.
Simmons' exit ends a fifth-wicket stand of 108 from 145 balls. Darren Sammy has come in ahead of Denesh Ramdin to join his successor as ODI skipper in the middle. A total of 41 runs came during the power play.
Simmons falls to the penultimate ball of the batting power play, Simmons cutting in the air to Moeen, who took a tumbling catch in front of Jordan after moving to his left.
Broad brings himself back on and watches his second ball disappear for four to backward point. It was short, wide and asking for it. Simmons didn't much encouragement and that stroke brings up the 100 partnership (from 136 balls) for West Indies' fifth wicket. Broad berates himself on the way back to his mark. It is just singles - one for each batsman - during the remainder of the over.
Jordan loses his control. He starts with two wides down the leg-side and then over-compensates, offering too much width, allowing Simmons to cut for four in fine style. A single into the covers brings Dwayne Bravo onto strike and he swings hard to send another cut racing away for four, this time a lot finer. Jordan responds with a couple of balls in the off-stump channel before a full toss to finish is helped for a single to square-leg by Simmons to make it 13 runs from the over.
Moeen continues into the power play, his three fielders allowed back are all protecting the leg-side boundary. Simmons rocks back and threads the gap between cover and extra cover for four. Simmons turns the strike over with a mistimed cut and Dwayne Bravo is immediately on the sweep for a single of his own. Simmons follows his partner's lead, sweeping for two to complete his 14th ODI half-century (81b, 4x4). A total of 10 runs from the over makes it the most expensive of the innings so far.
Dwayne Bravo is keen to open up the off-side and twice succeeds in getting his extravagant drives away, collecting a total of five runs for his effort. Simmons ends the over with two to square-leg after Jordan straightens his line. Time for drinks.
West Indies have taken the batting power play, mainly because they had to. There is a maximum of three fielders allowed outside the circle for the next five overs.
Moeen is a bit better than a 'part-time' spinner on this evidence. He's quite short so has to toss it up and gives it a fair old rip - but has also shown good control in this spell.
Bresnan returns for another spell and West Indies immediately press the launch button, Simmons running the first ball of the over fine of third-man for four. Simmons adds a miscued single after almost throwing himself off his feet and Dwayne Bravo runs hard for two when his weighted flick beats the man at short midwicket. There is also a wide for a too-short bouncer during an over costing eight runs.
West Indies still have the batting power play in hand, although it becomes mandatory from overs 36-40 if they haven't used it by then. Three singles from Moeen's over, the last of which takes West Indies to a collective three figures.
Dwayne Bravo thick edges a drive for a single from the opening ball of Jordan's over. The 50 stand between Bravo and Simmons is brought up from 96 balls via a leg bye and Dwayne Bravo finishes the over by driving for two off the back foot.
Moeen takes over from Tredwell. Will West Indies look to attack his more 'part-time' spin? Simmons jumps back in the crease to cut hard for four. Moeen's over improves thereafter, stringing together four dots to finish it.
Jordan fires one down the leg-side for the first wide of the innings. Dwayne Bravo almost throws himself off his feet while carving a square drive to the boundary. Quite a shot and that's his first four from his 37th ball faced.
Tredwell finishes off his 10 overs for figures of 1-23. He's bowled well, varied his flight and pace but West Indies haven't really looked to attack him after those early wickets went down.
England's fielding was awful in Australia but they have done well today, Root saving some runs with a diving stop at midwicket to deny Dwayne Bravo some runs. Decent over from Jordan, following Bresnan's example by targeting the stumps. Maiden.
It's been quiet partnership but is starting to build, worth 33 from 68 balls so far. A single for each batsman down the ground in Tredwell's latest over. He's got one left in his allocation.
Jordan is banging it into the pitch, trying to extract any life. There isn't much though. Couple of leg-byes in the over.
Tredwell's already got through eight overs and has gone for 19 runs, including only one four.
England's quickest bowler, Jordan, is into the attack for the first time. Simmons tucks into his first delivery, driving it square drive for three. Just pulled up short of the rope. Dwayne Bravo gets two later in the over, flicking into the leg-side with a high backlift and follow-through.
Game of patience at the moment, Bresnan is targeting the stumps with a full length. Again West Indies are limited to singles, one for each batsman.
The singles have started to come a bit more easily for West Indies since the drinks break, three from Tredwell's latest over. Everyone seems quite happy with that outcome.
Bresnan is picked off into the leg-side for five runs in all, three singles and a hard-run two. Bresnan getting his line too straight to the right-handers from his wide angle of delivery.
Both Simmons and Dwayne Bravo keen to use their feet and the full depth of the crease. Tredwell is mixing up his pace and flight nicely in this spell. Three singles in the over, including a flick into the leg-side from Dwayne Bravo to get off the mark.
Moeen takes a wicket and is then taken off. Bresnan back on for a second spell. Dwayne Bravo plays out a maiden defensively to take us through to drinks.
Simmons latches onto a short ball from Tredwell and cuts it hard through the off-side for four. He goes back into defensive mode thereafter, including padding up offering no shot on one occasion.
As one Bravo departs, another arrives, captain Dwayne replacing Darren in the middle. West Indies are in a big hole now on a decent pitch that is taking a bit of turn but nothing major.
Maiden international wicket for Moeen and it's a good one, Darren Bravo lbw propping forward in defence. Bravo reviews it but to no avail. Pitched in line from round-the-wicket and was turning back enough to be hitting the left-hander's leg-stump. West Indies are now out of reviews for the remainder of the innings, you only get one in ODIs.
There is a strong cross-wind at this ground, making it a big hit towards midwicket against Tredwell. Simmons cuts the first delivery of the over late for a couple but that's it for the over as Tredwell responds with a series of flighted offerings.
Broad is encouraged by what he's seen from Root and Tredwell, prompting him to bring another spinner, Moeen, into the attack for the first time in his international career. Nice start, also generating a touch of turn. Darren Bravo drives into the off-side for couple to get off the mark.
Tredwell is generating some nice turn from his round-the-wicket angle. There is a delay as the protective equipment is brought out so Root can go in under the helmet at short-leg to Simmons, who then plays and misses outside off-stump. Maiden.
West Indies wobbling on a blameless pitch. The latest new batsman, Lendl Simmons, opens his account with a bottom edged single into the leg side.
Full and straight does the trick for Bresnan against Edwards, who is bowled playing across it. It had looked on the cards earlier in the over when a couple of deliveries nipped back as Edwards unfurled big drives.
Darren Bravo, a left-hander, is the new batsman and plays forward defensively at his first two balls.
Smith departs to a bat-pad catch in Tredwell's opening over. He pushed forward and the ball looped up from inside edge and pad to Buttler, who took a diving catch after running forward from behind the stumps. A little bit of turn for Tredwell and it was just enough. Given not out on the field by umpire Gregory Brathwaite but England reviewed immediately and the replays showed a clear inside edge.
Bresnan into the attack and immediately tries a fuller length than Broad. Big lbw appeal against Edwards, who was playing back to a delivery that came in a touch off the pitch. England decide against a review and they were correct, replays show it was umpire's call on whether the ball hit in line with off-stump. Edwards responds by driving the next one between the bowler and mid-on for four, all timing.
Edwards is off the mark with a fierce drive for two. Root parried it two handed in his follow-through but think it was a bump-ball rather than a chance. Edwards keeps the strike with a single down the ground.
Smith finally breaks the run of dots with a pull for four. Wasn't all that short from Broad and he only just got enough bat on it. Smith edges between slip and gully for four more later in the over, he sort of played for it but wasn't in full control.
Slip and leg-slip in place for new batsman Kirk Edwards. He's solid in defence for the remainder of the over. Three maidens in a row, 20 deliveries since the last run was scored.
The Root plan pays off, Jordan pulling a stunning one-handed catch out of the air at short cover to send Powell on his way. Powell drove too early and Chris Jordan made the grab just above the turf moving to his right.
England building some pressure, Broad makes it back-to-back maidens and it is now 14 deliveries without a run being scored. The over ends with Smith twice being hit on the pads, the second of which was the better lbw shout. Replays confirm a thin inside edge.
Maiden from Root to the left-handed Powell, although he got away with a short one to finish the over. England have announced assistant coach Paul Collingwood has been nominated as a substitute fielder in preference to three other fit players in the touring squad. If needed, Collingwood will take the field wearing an unnamed or numbered shirt borrowed from an England supporter.
Smith pulls over the top of a slower-ball bouncer from Broad, through the shot too early if anything. Broad is the 31st man to captain England in ODIs. Just a couple of singles in the over.
Root is operating from round-the-wicket to the right-handed Smith. Birthday boy Tim Bresnan, 29, fumbles the pick-up to waste the chance of a run out after a yes-no interlude between the batsmen, Powell would have been struggling to get back. Smith is not messing about, launching the fifth ball over long-on for six. This is a flat pitch.
Skipper Broad opens up from the other end. Powell clips a cross-seam delivery off his pads towards midwicket and runs hard for three. Smith drives his first ball from Broad through extra cover for four, nothing more than a push. Smith keeps the strike with a single in front of square-leg.
Gentle start to proceedings, Root firing it in flat at the stumps. Both West Indies openers, Dwayne Smith and Kieran Powell, get off the mark with singles.
England have decided to open the bowling with Root's off-spin.
England have nine bowling options in their side today! Only Lumb and wicketkeeper Buttler don't turn their arms overs.
West Indies' most recent action was against Ireland, splitting a pair of T20s and winning the one-off ODI. Chris Gayle is sitting out this series in the hope of being fit for the World T20, where West Indies will be defending champions. Marlon Samuels (groin injury) and Nikita Miller are the men left out today from the 13-man squad.
Smith, Powell, Edwards, Darren Bravo, Simmons, Dwayne Bravo (capt), Ramdin (wkt), Sammy, Holder, Narine, Rampaul
Confirmation of ODI debuts for Lumb and Moeen - they will open the batting, with Luke Wright at three and Root at four. Eoin Morgan (knee) and Alex Hales (thigh) are both injured and sit out today's game. Ravi Bopara is making his 100th ODI appearance.
Lumb, Moeen, Wright, Root, Stokes, Buttler (wkt), Bopara, Bresnan, Jordan, Broad (capt), Tredwell
The match Broad was referring to at the toss was England's 29-run victory over University of West Indies Vice Chancellors' XI on Tuesday. Joe Root made a century in an England total of 290-8 and the UWI VP XI finished short on 261-7 in reply, spinner James Tredwell taking 3-39.
Broad has won the toss and England will bowl first. "We played on the wicket earlier this week and it was a bit tacky," said Broad. "It doesn't really matter, a 50-50 call." West Indies captain Dwayne Bravo admits he would also have bowled first.
Looks like Moeen Ali and Michael Lumb will be making their ODI debuts for England today after receiving caps - plus a pep-talk - on the outfield from none other than our very own David Lloyd.
England start the post-Andy Flower and Kevin Pietersen era in the picturesque setting of the Sir Viv Richards Stadium in North Sound, Antigua. The squad on duty for this tour, which features three ODIs and three Twenty20s, is actually the 15-man group (plus Notts seamer Harry Gurney) that will travel on to Bangladesh afterwards for the World Twenty20. Therefore, we have the slightly odd situation of England's T20 skipper Stuart Broad leading a 50-over side that will contain several short-form specialists. Anyway, it can't go any worse than what happened to England earlier this winter in Australia...
Welcome to our coverage of the first ODI of England's tour of West Indies. Play starts at 1.30pm (GMT).
