Skipper Kusal Perera hit an attacking 120 as Sri Lanka posted 286 for six in the third one-day international against Bangladesh on Friday. Perera's sixth ODI century and an unbeaten 55 by Dhananjaya de Silva guided Sri Lanka, who trail the three-match series 2-0, to a challenging total after they elected to bat in Dhaka. The left-handed Perera, who took over from Dimuth Karunaratne as captain in this series, smashed 11 fours and one six in his 122-ball knock. However, he was dropped on 66, 79 and 99 runs before being dismissed by teenage left-arm quick Shoriful Islam. Mahmudullah Riyad took a fine catch at long on after he dropped the opener one run away from his century. Perera and Danushka Gunathilaka put on 82 runs for the first wicket to lay the foundations of their total before fast bowler Taskin Ahmed took three wickets. Taskin bowled Gunathilaka for 39 and had Pathum Nissanka caught by Mushfiqur Rahim for a duck in the same over. Perera shared two key partnerships of 69 runs and 65 for the third and fourth wicket respectively with Kusal Mendis (22) and de Silva to rebuild the Sri Lankan innings. Bangladesh did well in the last 10 overs giving away just 69 runs to check the batting surge. Taskin, one of the two changes for Bangladesh in the match, finished with figures of 4-46. Sri Lanka handed ODI debuts to Ramesh Mendis, Chamika Karunaratne and Binura Fernando and also brought in wicketkeeper-batsman Niroshan Dickwella, who was run out for seven. str/sa/fk/lb
