Jason Roy's 162 seals England ODI series win against Sri Lanka

Jason Roy scored a second century in three games to give England a series-clinching six-wicket win over Sri Lanka in the fourth one-day international.

Roy made 162, the second-highest score by an England batsman in an ODI., external

It led England to 308, their second-highest successful ODI chase,, external with 11 balls to spare in a match reduced to 42 overs because of rain at The Oval.

Sri Lanka posted 305-5, a total increased by the DLS method, but could not stop England taking a 2-0 lead.

It is a third one-day series win in five since the awful World Cup campaign of 2015. The two defeats, against Australia and South Africa, were both in deciding rubbers.

Sri Lanka are still searching for their first win over England on this tour, with only Saturday's fifth ODI at Cardiff and a Twenty20 in Southampton on Tuesday remaining.

Opener Roy, brought into the England side immediately after the World Cup, has epitomised the improvement which has seen them score one-day runs faster than any other international team since the tournament in Australia and New Zealand.

Following his record-breaking stand of 256 with Alex Hales to win the second ODI, the Surrey right-hander could not be contained on a perfect batting surface at his home ground.

With a bottom-hand technique that saw him take 120 of his runs on the leg side, Roy three times shimmied down the pitch to hit sixes over long-on.

After Moeen Ali, opening because Hales had a stiff back, edged behind, Roy shared 149 with Joe Root, who cut and pulled his way to a much-needed 65.

Dropped by bowler Suranga Lakmal on 133, Roy seemed certain to better the 167 not out made by Robin Smith against Australia in 1993 when he missed a swipe at a Nuwan Pradeep slower ball and was bowled.

That left Jonny Bairstow and Jos Buttler to complete England's fifth successful chase in excess of 300 and their third in the past year. A feat once remarkable for this team is now becoming routine.

Asked to have first use of such a true surface, Sri Lanka put in their best batting effort of the series but, despite four men passing 60, lacked a match-winning contribution.

Kusal Mendis added drives to his usual strong back-foot play in 77, while Danushka Gunathilaka drove well and worked to the leg side effectively in making 62.

They shared 128 for the second wicket but both fell after the rain, which arrived in the 19th over, to the leg-spin of Adil Rashid, who was without the accuracy he displayed earlier in the series.

Despite the platform that has been previously lacking, Sri Lanka were never able to fully kick-on, even though Dinesh Chandimal took sixes over mid-wicket and third man in his 63.

After he was bowled by David Willey, it was left to Angelo Mathews to provide the late impetus with an unbeaten 67.

Eighty-eight runs came in the final nine overs and the adjusted total looked at least competitive. Roy proved it was anything but.

Man of the match Jason Roy on BBC Test Match Special: "To contribute in a big way like that is extremely special. I'll never forget that.

"A lot of hard work has been put in and we reap the rewards. These are very exciting times for English cricket."

England captain Eoin Morgan: "Jason Roy is making the most of his form. That is a big thing in international cricket - you cash in and he is certainly doing that.

"It is nice for him to be second in the list. He has played a magnificent innings."

Sri Lanka captain Angelo Mathews: "I thought we had a good score on the board. Our bowlers were pretty ordinary and Jason took the game away from us."
