Nuwan Kulasekara was a valuable part of the Sri Lanka World Cup teams, contributing to their runner-up finishes in the 2007 and 2011 tournaments. As a right-arm fast bowler, he marked his one-day international debut in 2003 against England with an impressive performance, taking 2-19. His Test debut came in 2005, but due to inconsistent form, the lively seamer was omitted from the Sri Lanka squad for a period of eight months in 2006. However, Kulasekara made a strong comeback, securing his place in the 2007 World Cup squad and becoming a consistent member of the ODI team. His skills as a bowler were acknowledged when he briefly held the No.1 ODI bowler ranking in 2009. Notably, he recorded his career-best figures of 5-22 against Australia in early 2013. Kulasekara is not only an asset with the ball but also proves his worth with the bat, having achieved a high score of 73, also against Australia, in 2012.
