On 13 June 2013, against England in 2013 ICC Champions Trophy, Kulasekara helped skipper Kumar Sangakkara score a century and guided Sri Lanka to victory. Sangakkara and Kulasekara added an unbeaten 110 runs for the fourth wicket. In the powerplay, Kulasekara launched Graeme Swann's off-spin for two successive leg-side sixes and continued to an unbeaten 58 from 38 balls. Soon after Sangakkara scored his hundred, he fell in mid-pitch while running. Recognizing the danger of being run out at the wicket-keeper's end, Kulasekara ran alongside him to ensure that he (not Sangakkara) would be run out. After the Champions Trophy, Sri Lanka went to the West Indies for a triangular series with India. During the match against the West Indies, Kulasekara dislocated the ring finger of his left hand.
