Sri Lanka defeated England by 10 wickets in the first ODI at Colombo's R Premadasa Stadium. The hosts needed just 12.3 overs to chase down England's modest 262-run total, with openers Pathum Nissanka and Kusal Mendis sharing an unbroken 128-run partnership.

England's batting lineup failed to capitalize on a decent platform, losing wickets regularly after Jason Roy's 49 off 34 balls. Joe Root managed 38, but the middle order couldn't accelerate. Spinner Maheesh Theekshana claimed three wickets for 41 runs in his 10 overs.

This comprehensive victory gives Sri Lanka early momentum in the three-match series. England must regroup quickly, especially with limited-overs tour preparation ahead of their busy international calendar. Theekshana's economical spell proved decisive.

Both teams now turn attention to the remaining two ODIs. England's batting vulnerabilities under pressure will face further scrutiny as they seek to level the series.
