London, Jul 4: Sri Lanka captain Tillakaratne Dilshan believes a one-day series win against England is within his side's grasp after a six-wicket victory at Lord's put the tourists 2-1 up with two to play.
Dinesh Chandimal''s unbeaten 105, the 21-year-old's second hundred in just six matches at this level, saw Sri Lanka capitalise on a disciplined bowling display after they held England to a sub-standard 246 for seven.
Chandimal won the match for the World Cup finalists with 10 balls to spare by smashing James Anderson for four.
Sri Lanka might have got there sooner had not Angelo Mathews, whose one not out took 21 balls, been so determined to make sure Chandimal got to a hundred.
Sri Lanka may have lost their rain-affected opener at The Oval by 110 runs but their second victory in three days, following their 69-run success at Headingley, has seen them come from behind to take the lead.
"We are playing good cricket, if we play like this we can win the next two matches," Dilshan told reporters.
So determined was Mathews to make sure Chandimal, who eventually reached three figures with a six off medium-pacer Tim Bresnan, got to a hundred he played out a maiden in the 47th over to the visible despair of his captain.
"That disappointed me a little bit but they are youngsters, they are learning every time in the middle," Dilshan said.
"Getting a hundred at Lord's is really special for him (Chandimal).
However, Cook insisted: "We've played on some pretty flat pitches and what we are thinking is the right way and we just need a little luck to go our way."
Stuart Broad, largely ineffectual during England's 2-1 Test series win against Sri Lanka, went wicketless for the third match in a row, the fast-medium bowler conceding 52 runs in 10 overs at Lord''s.
Despite being the son of match referee Chris Broad, the former England opening batsman, he arrived at Lord's on the back of being fined 50 percent of his match fee at Headingley.
Broad was punished for "unacceptable and offensive remarks" to New Zealand umpire Billy Bowden regarding a rejected lbw decision.
However, Cook said it would not surprise him if Broad -- England''s Twenty20 captain -- came good at the seamer''s Trent Bridge home ground in Nottingham, where the fourth match of this series take place on Wednesday.
"At the moment it's not quite going for Broady, a bit like the Tests, but this is what cricket does," said Cook.
"If he gets a five-for next week at his home ground next week it will be worth it.
"He overstepped the mark (at Headingley), he accepts that."
