Perera continues to toil away, but he has very little to show for his effort. Five risk free runs come off the over as India march towards to the final.
Mathews brings himself on to bowl in place of Kulasekara. The Sri Lankan skipper is extracting a lot of seam movement, but the batsmen are watchful and are doing it well. A big appeal is turned down, but the captain has a chance of claiming a wicket and has called for the review straight away. A big inside edge ends that review.
The rotation of strike is starting to happen more often. The two batsmen appear to have a good understanding and trust each other when it comes to calling.
The partnership is working so well. After seeing his partner struggle, Rohit takes on Kulasekara and cracks a boundary through point. Rohit sits back in his crease and plays a short-arm pull through square-leg for yet another boundary.
Dhawan finds Perera more to his liking as he creams a cover drive to the boundary. A streaky inside edge brings up the 50. Once again the openers have done the business for India.
Dhawan is struggling to lay bat on ball as Kulasekara is extracting some serious movement. A quick single gets him done to the safer end.
Perera now finds the edge of Rohit's bat, but it falls just short of slip. Both batsmen aren't used to scoring this slowly in this tournament and are starting to look a bit restless.
A very tidy Kulasekara over is treated with respect. Dhawan leaves and defends a string of deliveries, but he looks extremely comfortable. The brilliant over ends with the edge. Dhawan is dropped at 1st slip. Will that cost Sri Lanka.
Perera replaces Malinga. He didn't trouble the scorers, so will be keen to make an impression with the ball. The bowler drags one down and Dhawan jumps all over it, cutting it hard to the boundary.
Even though the ball is new and batting is tough in the middle, the Indian pair have done a great job of scoring. On a surface such as this one, you will eventually get a ball with your name on it, so it is important to score while you are out there.
The Indian batsmen are more familiar than most with Malinga and have dealt with him well so far today. A third consecutive short ball makes the batsman play. Dhawan upper-cuts over third-man for six.
A huge appeal is turned down. The Sri Lankan's decide not to review and Rohit survives a close call. A peach beats everyone and the cruels result for the fielding team is two leg-byes.
Malinga has changed his line of attack to the left-hander, by opting to come around the wicket. Dhawan is hitting a few good shots straight to fielders and looks itchy to cut loose. A sweet drive crashes into the boundary boards at deep cover.
Kulasekara finds the edge but it lands safely and runs away for four as India deal in boundaries. After a single, Dhawan finds life tough against the ball leaving him.
Malinga is given the second new ball. he will be looking to strike because if India are not 2 or 3 wickets down after 10 overs then they will run away with this game. Malinga is getting some nice shape back into the left-handed batsman, but Dhawan is playingis confidently. The run machine is off the mark with a crisp drive for four.
Kulasekara opens the bowling. He has all the skills to be just as effective as Kumar was earlier. The swing is still around and one tails into Rohit, beating his inside edge. A glorious cover drive gets India off and running.
Sri Lanka were inserted on a sporting wicket. They lost a few early wickets and tried to build for a charge in the final overs. The innings however, never got going as the Indian bowlers kept a strangle hold on the run rate. The World Champions will require 182 runs for a place in the final of the Champions Trophy. Even though the pitch is a bit tricky, it is difficult to see any other result than an Indian win.
Ashwin will bowl the last over of the innings. WICKET. Mendis runs straight past one and is stumped. Malinga swings his first delivery into the leg-side. Another catch is dropped and the batsmen run three. A member of crowd holds up play by running onto the pitch. The last ball of the innings his swung away for a boundary by Malinga.
Dilshan is showing some guts as he is batting in obvious pain. It may be better for the team however, if a batsman who was able to run came in for the final two overs. His final over yields 6, but Sharma will be happy with his contribution today.
Its unusual to see a spinner bowling so many overs at the death, but Ashwin has put his hand up. WICKET. Kulasekara see's the ball is leg-side, he tries to move his legs out of the way so as to earn the wide. It is mis-judged as the ball takes the leg stump and he is bowled.
Sharma continues as he is given the duty of keeping things calm at the death. Perera is a big lad but is yet to connect with one of his wild swings. WICKET. Perera finally lays bat on ball but finds the man on the mid-wicket boundary. The fielder makes no mistake and India keep control of the innings.
Ashwin brings the false shot out of Mathews and Kholi drops the chance on the long-on boundary. WICKET. The next time Mathews gets on strike, he tries to go over the top again. The leading edge is found and the looping catch is taken at cover.
Sharma is short and pulled for a boundary by Mendis to take Sri Lanka to 150. A quick single gives Mathews his individual 50 and it will be up to him to take advantage of the last 5 overs.
A string of singles means that Ashwin's over costs five runs. He won't be unhappy with that especially seeing as the death overs have started.
Yadav is greeted by a pull for four by Mathews. The Sri Lankan skipper then tries a scoop but the ball thunders into his thigh pad and the batsman is left looking a little silly. Some running repairs to his bat end the over.
Ashwin is not looking nearly as threatening as Jadeja, but he is still doing a reasonable job for his team. The seamers will come back into the attack shortly.
Jadeja speeds through an over in a minute. He has now completed a very economical 10 overs and once again has down a great job for his team.
Ashwin gets through another over. It goes for 7 runs though and releases some pressure.
Jadeja zones in on the foot marks outside the left-handers off-stump. He is trapped down at the strikers end and only manages to get a single off the last ball of the over.
Ashwin now finds some turn and all of a sudden the pitch looks like a spinners dream. The runs have dried up and the batting powerplay has worked in the fielding team's favour once again.
Jadeja is in again, so the powerplay has not changed Dhoni's game plan. WICKET. This one won't be reviewed as Jayawardene is clean bowled. Some big turn greets Mendis and hits the left-hander in the ribs.
The batting powerplay has to be taken now. The next 5 overs will be very important, as it could shape the way that this innings will end. Ashwin bowls with an extra man in the ring, but the batsmen are set and continue to find the gaps as they rotate the strike.
The twin spin threat continues as Jadeja bustles in for another over. A lovely chip over cover, with the spin, brings Jayawardene two runs.
Ashwin bowls around the wicket. Another big lbw appeal is turned down by the umpire.
Some great foot movement allows Jayawardene to cut the left-arm spinner for a boundary. The batsmen are looking good against the spin, perhaps it is time for a seamer to try and make a breakthrough.
The drinks break has also seen the end of the Dhoni experiment. He is back behind the stumps and Ashwin comes into the attack for the first time. A sloppy piece of keeping gives away 5 wides and brings up the 100.
WICKET. Jadeja has struck as he has done so many times in this tournament. Mathews this time has called for the review. The Sri Lankan captain is given a life-line. The ball would have bounced over the wickets and the decision is reversed for the second time in the innings.
Dhoni bowls the 30th over and Ashwin is stil nowhere to be seen. The captain's of both teams are doing a good job.
Jadeja finally gets one to turn. Neither team will be upset with what is happening. Sri Lanka are conserving wickets, while India are keeping a lid on the scoring rate.
Dhoni is generating no great pace but a little wobble in the air is giving the batsmen something to think about. The bowler looks a lot more effective now that Karthik has come up to the stumps.
Jadeja is being worked around nicely. He is not overly expensive, but he is not looking anywhere near as effective as the seamers have been.
The Dhoni, Jadeja bowling combination is just leaking a few singles and the batsmen are starting to look comfortable at the crease. A shorter delivery is cut away and Jayawardene picks up another boundary.
Jadeja continues, and if nothing else, will improve the over rate. A fielding lapse in the outfield gives Jayawardene a boundary after a powerful sweep.
Dhoni is into the attack and the crowd errupts. WICKET. The captain strikes, but Jayawardene has called for the review. The batsman has got an inside edge, so the decision will be reversed. Jayawardene survives and Dhoni is denied his 2nd ODI wicket.
Dhoni has exchanged the wicket-keeping pads and will bring himself on to bowl. The conditions demand an extra seamer, so the captain is taking the responsibility. For the time being, Jadeja takes the ball and spin is into the attack.
The Sri Lankan captain starts the counter-attack. He advances and smashes Sharma over mid-wicket for six.
Mathews works Yadav for two into the leg-side. The scoreboard is just starting to tick over for Sri Lanka now. A three through point brings up the 50 for the under-dogs.
Sharma gets Jayawardene to hop around as some exaggerated bounce keeps the batsman honest. Even the rare loose delivery is only cut away for a single. Mathews is off the mark with three through the covers as the outfield is still very slow from the morning rain.
Yadav comes back into the attack. It is almost unheard of for India to have bowled nearly 20 overs with no sign of spin, but Dhoni is adjusting to conditions and is keeping the pressure on Sri Lanka. Yadav backs his bowler upm by delivering a high quality over.
Sharma is applying the squeeze to Jayawardene, who is still yet to get off the mark. The batsman is squared-up and an edge flies down to third-man to eventually gain Jayawardene his first run. WICKET. The shame combination strikes. Sharma finds the edge of Sangakkara's bat and Raina does the rest at 2nd slip.
An elligant push off the front-foot brings Sangakarra two runs. He then takes a quick single. Sri Lanka need to rotate the strike a lot more if they are going to get their innings back on track. Dhoni has come up to the stumps in an attempt to keep the batsmen in their crease. This will allow the ball to swing and brings the lbw back into the equation.
Sharma resumes the attack after the drinks break. WICKET. Raina takes a wonderful catch at second slip, low and to his left. Thirimmane is caught and the break has done the trick for India. The two big guns for Sri Lanka are now at the crease together.
kumar remains around the wicket. An lbw appeal is turned down bacause Sangakkara gets his pad outside the line. Kumar completes another maiden and the players will enjoy a drink.
Thrimanne joins the party. A mirror image of Sangakkara's stroke in the previous over yields the same result. Normal servive resumes after the boundary as a string of dot balls ends the over.
Kumar starts his 7th over as Dhoni is bowling him while the conditions are in the swing bowlers favour. Kumar comes around the wicket and Sangakkara opens his arms. He carves the bowler through point for the first boundary in quite some time.
Sharma comes into the attack as Dhoni makes the first bowling change. The bowler looks to be enjoying the pitch. For the first time in the tournament, he is getting some seam movement.
Kumar continues, as expected. Hawk-eye shows that an lbw appeal in the previous over would have been given out, if India has asked for the review. Thirimanne gets a bit of good fortune. Another extremely tight over comes to an end.
Thirimanne gets an inside edge onto the unprotected part of his knee. The physio is working over-time today as he is back on the field and helping the batsman who is in obvious pain. The left-hander is back in action and gets right behind the line, defending well.
Kumar might be given an extended spell as he is best while the ball is new and still swinging. If he manages to snaffle another couple wickets, then the spinners will really be able to control the middle overs.
The damp outfield means that it is difficult to time the ball to the boundary. Another sweet stroke yields three runs for Sangakkara. There is a serious contest between bat and ball which is better than the bowlers being completely dominated, as so often happens.
Both bowlers seem to have found the right length for this pitch. The batsmen are being drawn forward and are fighting to just survive. Three runs through the leg-side prevents back to back maidens.
Yadav finds his straps and for the first time sends it down at more than 140km/h. He beats the bat and produces a testing maiden.
Sangakkara flicks one to fine-leg and Dilshan struggles to get to the strikers end. Enough is enough and he has retired hurt.
Dilshan looks in good touch as he smokes two boundaries. He then clips one into the leg-side and limps back for two. He is hurt and the physiotherapist comes on to help. Dilshan decides to continue.
There is just enough swing to find the edge this morning. The batsmen would be wise to grind out the first 10 overs and then look to increase the scoring rate from there. WICKET. The Kumar has found the edge due to a bit of swing. Perera is caught at second slip after attempting a drive.
Yadav takes the other new ball and will look to generate some pace. A good shape on the ball beats the outside edge of a Dilshan drive.
Kumar takes the first over of the 2nd semi-final. Early indictations suggest that this is a very slow wicket. A leg-side delivery is clipped through square-leg for the first boundary of the day.
MDKJ Perera, TM Dilshan, KC Sangakkara, DPMD Jayawardene, BMAJ Mendis, AD Mathews, HDRL Thirimanne, KMDN Kulasekara, HMRKB Herath, NLTC Perera, SL Malinga. Two changes have been made. Mendis is in for Chandimal and in what I think is a good change, Perera comes in for Eranga.
S Dhawan, RG Sharma, V Kohli, KD Karthik, SK Raina, MS Dhoni, RA Jadeja, R Ashwin, I Sharma, B Kumar, UT Yadav. The team is unchanged as expected.
It is overcast and should be a stop-start day with plenty of rain showers around. The pitch has a little more moisture than previously, so it will be important for the batsmen to see off the new ball. The decision to chase will also help the Indian's if the D/L method is called on later in the match.
India win the toss and decide to bowl. They will look to make the most of the overcast conditions and strike early. The Sri Lankan captain says that he would also have bowled first. It will be tough in the early overs for the batsmen.
The main cover has found its way back onto the square because rain is expected shortly. Let's hope that it is just a passing shower.
The toss is due for 9:40 GMT and play will start at 10:00 GMT. There will be no deduction in overs, if the rain stays away.
Morning rain has thankfully cleared, but it has left a wet outfield. This has resulted in the toss and possibly the start of play being delayed. The umpires will conduct an instrection after the field has been dried and we will keep you posted on the outcome.
Hello and welcome to the second Champions Trophy semi-final, this time in Cardiff between Sri Lanka and pre-tournament favourites India. The winner will join England, who beat South Africa, in the final on Sunday.
