England completed a clean sweep over Sri Lanka after winning the one-off T20 international by eight wickets to add to their Test and one-day series success. Liam Dawson took three wickets on debut at the Ageas Bowl to restrict the tourists to just 140, before Jos Buttler struck 73 to see England home with 15 balls to spare.
The result sees the hosts prevail 20-4 in the Super Series, leaving Sri Lanka winless following a miserable tour. Eoin Morgan's side were playing their first T20 international since the World Cup final defeat to the West Indies but they showed no ill-affects from the harrowing loss in Kolkata to record a comfortable win.
Morgan said: "Apart from the first game [the tie at Trent Bridge in the one-day series] everything has seemed to have clicked and get better game on game. Tonight was our peak over the last four white ball games. I thought Liam Dawson was fantastic, Tymal Mills showed us exactly what he did. Two guys, who if there were nerves on debut, there were none today."
Sri Lanka had earlier won the toss and inserted England, much to the delight of Morgan who was boosted by the inclusion of Tymal Mills and Dawson for their first international appearances. Mills' express pace forced openers Kusal Perera  and Danushka Gunathilaka  to seek alternative avenues for runs and it would be their undoing as first Lima Plunkett and then Dawson [3 for 27] reduced them to 58 for 2 inside seven overs.
Captain Angelo Mathews  was unable to rouse the innings amid some intense England fielding and when the in-form Dinesh Chandimal  was dismissed the away side were threatened to end their tour with a whimper. The wicket of Nuwan Padeep, as Chris Jordan [3 for 29] claimed his third wicket from the final ball of the innings, saw them needing to defend 141 to bring an air of respectability to the summer.
Jason Roy was bowled by Mathews from the third ball to give Sri Lanka brief hope, encouragement which was swelled by the stumping of James Vince. However, Buttler soon took control with four sixes and three fours and along with skipper Morgan [47 not out], who survived being dropped by Mathews, put on 114 for the third wicket. England cruised to the routine win - their 14th in the last 16 T20 matches - which maintains their decent form with the white ball.
"140 was an average total on that wicket," a despondent Mathews told Sky Sports. "It was stopping and turning a little bit but 140 was not enough on that wicket. We looked for too many runs up front, too early. It was a big ground as well and we kept losing wickets. We have to take early wickets. We got a couple of wickets but Eoin's catch was pretty crucial and I dropped it.
"I could have caught it and it could have made the difference but I couldn't and we let hm off the hook and we let him off the hook. We showed fight in bits and pieces. One day we showed fight and the next day we were inconsistent and that is something we need to work hard on. There are lots of positives. Unfortunate we didn't have the bowlers to put the pressure on the England batsman. It's been a tough series."
