Kusal Mendis smashed his sixth ODI hundred and led Sri Lanka to a commanding 99-run victory in the third and final one-day international as the home team clinched the series 2-1. Mendis marshaled Sri Lanka to 285-7 with an aggressive 124 off 114 balls after captain Charith Asalanka won the toss and elected to bat.

The Bangladeshi batters struggled against the pace of Dushmantha Chameera and Asitha Fernando, who shared six wickets between them to bowl out the visitors for 186 and give Sri Lanka an eighth successive win in a home ODI series.

Fernando clean bowled Tanzid Hasan (17) with a searing yorker in the third over of the chase and Najmul Hossain Shanto then deflected Chameera's incoming delivery back onto the top of the stumps for nought as the visitors slipped to 2-20. Sri Lanka's middle-order struggled against the spin as Dunith Wellalage (2-33) and Wanindu Hasaranga (2-35) struck with regular intervals and the Bangladeshi batters also couldn't put up strong partnerships.
