Last over, and Doherty starts off with a full toss which Gayle casually sets aside for another 97-metre six! Pollard gets in on the last bit of action with a sterling slog shot over midwicket fox six! Pollard isn't done - he smashes another full toss over long-offfor another huge one. He goes again, can't you believe it!!! Straight back over the bowlers head - that is HUGE! MASSIVE! WOW! Pollard goes huge for the last of the over but skies it really high - Warner gets under it and takes a fairly straight forward one. That's the over and the innings - what a game this is going to be!
Starc bowls his last over and Gayle shows who is boss by slogging one over deep midwicket, over the ropes, for six! Another fielding wobble from Australia as one bounces on its way to Michael Hussey who misjudges it completely as it speeds away for four! Pollard ends the over by scooping one over the keeper's head for four - that is just SO cheeky... But effective!
Gayle spent the last few minutes on the ground receiving treatment for what looks to be some kind of rib injury - he chooses to continue but looks in a lot of pain. Pollard picks up three from the first two of the over. Well, if he is in pain it isn't showing as he dispatches a boundary as he pulls Cummins wide of deep midwicket for four. Pollard does likewise on the last of the over, four more!
Gayle picks up four from Watson's first ball with a thick inside edge beating the man at deep square.
Cummins gets punished for a poor delivery on the fourth as DJ Bravo goes for height - and just enough distance - to slot it straight over the bowler for six. WICKET! Second attempt by Cummins gets his man as Bravo drives it straight into Bailey's hands while trying to go over the top of extra cover. Kieron Pollard joins Gayle in the middle and gets off the mark with two immediately.
Gayle gets a very thick inside edge as he smashes Hussey away for four. Gayle changes his gloves then lofts Hussey over the top and seats it somewhere on the second tier! He tries another big one and Starc comes running in off the ropes to try get it - he puts his body on the line as the ball bounces short and smashes into his chin - OUCH! Gayle brings up his fifty with a four run boundary by sticking his bat out at a wide one and getting a touch on it as it races away.
Bravo climbs into Hogg's first of the over and hammers it again for a flat six. This is quite an onslaught from West Indies! A couple more singles mid-over to either batsmen and Bravo finishes the over with a drive down the ground for one.
Bravo drives one away for a couple before absolutely smashing one over long-on for six - that was a massive one! Hundred up in the over. Gayle guides another away off the thigh for four to end the over.
Starc returns for another run but gives away four nasty byes wide down the leg side - that's not like him, an unusual bowling performance to say the least.
David Hussey gets a chance now as he bowls his first offbreak of the day. A few singles to start. Hussey isn't left amused as one goes straight through Wade behind the stumps for four byes.
Gayle has smashed another one - this one is HUUUUUUUUUGE! He dispatches Doherty far over the long-on boundary for six! A few more singles all round ends the over.
Another boundary! Bravo smashes one to long-off but it drops somewhat short and skids off the surface and away over the ropes for four!
My word, Samuels has hit one so hard through the covers - imagine one flying at you, chest height, at that speed! Samuels tries to repeat the slog with another big one but he's totally missed it and Cummins gets his man with a well disguised slower ball - clean bowled! Dwayne Bravo joins Gayle in the middle and grabs a single first one up.
Samuels is ripping this bowling apart - Brad Hogg gets introduced by Samuels smashes his first one straight back over his head for another maximum. Hogg does alright to finish the over with four dots and a single from the last.
Xavier Doherty joins the bowling attack now - Samuels sits easy for the first few but eventually gets hold of the fourth and smashes it really far far far away over the long-on boundary for another maximum! If that's not enough, Gayle smashes the last of the over far over midwicket for another HUGE six!
Samuels guides a leg-bye down to fine leg for a single. Gayle looks a little frustrated as he comes down the pitch to Watson and tries to hoof him anywhere but in the ground. Gayle finally makes contact - that's a HUGE one as he smashes it over cover - a slog drive if you want to call it that! SIX RUNS!
Pat Cummins introduced into the attack while Samuels picks up a single off the first and Gayle gets just a single from the next. Samuels plays the most glorious drive straight past extra cover for four!
Gayle picks up another single off the first. Charles nicks one to slip where Cameron White gets one which drops slightly short as he dives away to stop anything more than a single. Starc gives away another extra in the form of a wide. WICKET! Charles tries to hit through the line but he's done nothing more than edged one to the 'keeper for the simplest of catches. Marlon Samuels comes to the crease for the last ball of the over. Samuels gets an inside edge away for a single to end the over.
Small LBW appeal on the first as Charles faces up to Watson - the Umpire has none of it and the batsmen take a sneaky leg-bye. Gayle doesn't waste any time as he sets off for a single off his first ball faced. HUGE SHOT from Charles who smashes Watson over the top of midwicket - the Umpire asks for some assistance with this one and replays seem to show it lands inches short of the ropes on its way to the advertising boards. Charles goes for a biggie on the onside again, doesn't time it brilliantly but he manages four nonetheless. Excellent over for the Windies.
First extra of the game gives the first runs as Starc drops in one with too much of an angle to swing back into the batsmen. Charles spends most of the over scooping the others out from the pitch. First single from the bat though as Charles finds a quick single to mid-off.
Chris Gayle opens the batting with Johnson Charles while Mitchell Starc takes the first new ball.
The players are on the field for the anthems, and the Australian ladies, who won their fixture against the Windies this morning to reach the final against England, are watching their counterparts from the stands.
The wicket is taking strain after two weeks of action, and it's a dusty, crumbling track that will probably help the spinners. Last night's game between Sri Lanka and Pakistan showed that a score of 140 is fairly decent, while earlier in the tournament it would have been about 30 runs short.
