I was disappointed with what happened in Colombo. I had got a start and couldn't finish. Here I was determined to bat through the innings and very satisfied," he said after the match, as quoted by the ICC. Bangladesh captain Mehidy Hasan Miraz, who was one of six batters to reach double figures in the Pallekele contest with 28, rued the lack of any meaningful partnerships during the run chase as the Asian side were dismissed in the 40th over in reply."We just couldn't put together partnerships like Sri Lanka. They had a big partnership after they lost three wickets for 100 runs. Partnerships in the middle overs are crucial. We got a couple of 40s, but winning is hard without these partnerships in ODI cricket," Mehidy said. With this win, the Islanders clinched the three-match ODI series 2-1, as per the International Cricket Council (ICC) official website.Mendis smashed a superb 124 from just 115 deliveries as Sri Lanka amassed 285/7 in the series decider, and that proved too much for Bangladesh as they were bundled out for 186 in reply.It saw Sri Lanka clinch a 2-1 series triumph, with Mendis hitting his sixth ODI century and deservedly named Player of the Series for his 225 runs across the three matchesSri Lanka squad: Charith Asalanka (c), Pathum Nissanka, Kusal Mendis, Dinesh Chandimal, Kusal Perera, Kamindu Mendis, Avishka Fernando, Dasun Shanaka, Dunith Wellalage, Maheesh Theekshana, Jeffrey Vandersay, Chamika Karunaratne, Matheesha Pathirana, Nuwan Thushara, Binura Fernando, and Eshan Malinga.
