Nobody who watched the first game of this series would have predicted Sri Lanka finding a way to come back and level things up at Headingley, but cricket has a wonderful habit of humbling the overconfident. Kusal Mendis walked out and played one of the finest ODI innings seen in England this summer, a composed and authoritative 121 that dragged his side to a total England simply could not chase down. The tourists ran out winners by 16 runs, and suddenly this three-match series has a very different complexion heading into Sunday's decider at The Oval.

Mendis Takes Centre Stage

As a former coach, I have watched a lot of match-winning innings over the years, and what impressed me most about Mendis here was not just the runs on the board but the manner in which they were accumulated. Sri Lanka needed their captain and talisman to stand tall in a high-pressure away fixture, and he delivered precisely that. His 121 was the backbone of the Sri Lankan total and gave the bowlers something genuinely competitive to defend. When you have a player of that calibre firing at the top of the order, it changes everything about how a side approaches a game — both with the bat and later out in the field.

England Fall Short Despite the Chase

England's pursuit never quite clicked into the rhythm their batting line-up is capable of producing. A deficit of 16 runs at the final whistle tells you this was not a rout, but rather a slow unravelling — the kind of defeat that is arguably more frustrating than being blown away. There was also a significant blow to England's camp during the match, with reports emerging of a Buttler injury that disrupted the home side's plans mid-chase. Losing a player of Jos Buttler's experience and finishing ability, even briefly, can derail even the most well-structured run chase. Sri Lanka's bowlers deserve credit for holding their nerve and executing under pressure at a ground that can be tricky in the closing overs.

Series Decider at The Oval

With the three-match series now level at one apiece, everything rests on Sunday's final ODI at The Oval. From a betting perspective, this result will have shifted the outright series odds considerably. England would have been heavy favourites heading into the second match, but Sri Lanka have now demonstrated they are more than capable of winning on English soil when Mendis and the bowling attack fire together. The Oval tends to offer more to batters than Headingley, which could suit England — but then again, Mendis has just shown he can score big runs anywhere. Expect the markets to tighten significantly ahead of Sunday, with Sri Lanka now very much live in this series.

What to Watch at The Oval

The key question for both sides is squad fitness and selection. England will need clarity on Buttler's availability, as his presence in the middle order could prove decisive in a series decider. For Sri Lanka, the challenge is maintaining the same level of intensity that produced such a disciplined performance at Headingley — repeating that kind of showing against a wounded England side will be no small feat. If Mendis turns up again in that kind of form, however, the tourists will fancy their chances regardless of conditions.

This has turned into a brilliant little series, and Sunday's finale at The Oval promises to be a genuine contest. Sri Lanka deserve enormous credit for fighting back when the pressure was on. As for England, they will be desperate to put things right on home soil. Do not miss it.
