After the third match in Bristol was rained out, England won the one-day international series against Sri Lanka 2-0.
England, who also won the Twenty20 series 3-0, appeared to be on track for another victory when they dismissed a hapless Sri Lanka for 166 in 41.1 overs.
However, heavy rain fell shortly after 15:00 BST, during the change of innings, making further play impossible. The game was called off at 16:15 due to puddles forming on the outfield.
Tom Curran impressed with 4-35 in 10 overs in another strong England bowling performance. After Chris Woakes and David Willey had reduced the tourists to 42-4, Curran ripped through their middle order.
When England takes against Pakistan in the first of three One-Day Internationals on Thursday, they will almost certainly be put to the test. Following that, there will be a three-match T20 series.
Sri Lanka has had a miserable tour, with the only saving grace being that the rain prevented them from suffering a sixth defeat in six games.
They were 46-3 in the first ODI in Chester-le-Street, 21-4 at The Oval, and four down in nine overs here. Woakes, in particular, was able to swing the ball throughout, but the majority of wickets were taken by bad shots rather than by good bowling.
Dhananjaya de Silva, who had scored 91 in the previous game, was one of two batters dismissed, Oshada Fernando smashed Curran to mid-off to make the score 63-5, and Asitha Fernando was run out in comedic fashion.
Because the opposition was so bad, England learned little from the series, but four wickets were a welcome boost for Curran. The Surrey bowler, whose brother Sam took 5-48 at The Oval, had only three wickets in his previous 11 One-Day Internationals.
Jonny Bairstow, the wicketkeeper, assisted him by taking a brilliant diving one-handed catch to dismiss Chamika Karunaratne for Curran’s third wicket.
The victory keeps England atop the Super League, which serves as qualification for the next 50-over World Cup. Sri Lanka is currently ranked 11th and is in danger of failing to qualify for the 2023 showpiece if their results do not improve.
