Chasing a challenging target of 358, Sri Lanka were bowled out for 304 in 46.4 overs despite a valiant effort from 23-year-old Pavan Rathnayake, who scored his maiden ODI century. Rathnayake top-scored with 121 off 115 deliveries and was the last man to be dismissed. Opener Pathum Nissanka provided a brisk start with a 25-ball half-century, but the lack of substantial partnerships saw Sri Lanka lose momentum in the chase.
Earlier, England posted an imposing total of 357 for 3 after winning the toss and opting to bat first. They suffered early setbacks with the dismissals of openers Ben Duckett and Rehan Ahmed, but Joe Root and Jacob Bethell steadied the innings with a solid rebuilding effort. Bethell scored 65 off 72 balls before being dismissed, while Root went on to complete a superb century. Harry Brook also struck an impressive hundred, powering England to a strong finish.
The victory sealed the series for England, highlighting their batting depth and composure under pressure, while Sri Lanka were left to rue missed opportunities despite individual brilliance.
