Warnakulasuriya Patabendige Ushantha Joseph Chaminda Vaas (born 27 January 1974) is a former Sri Lankan international cricketer, who played all forms of the game, and a former ODI captain.
Often described as the 'most penetrative and successful new-ball bowler Sri Lanka has produced' Vaas currently holds the record for the best bowling figure in ODI history, and only bowler to take an 8 wicket-haul in ODIs.
During his time, Vaas often played a supporting role to Muttiah Muralitharan, Sri Lanka's off spinner and leading wicket taker.
In 2004 he gained international recognition when he was selected for the World Test and one-day XI at the inaugural ICC Awards.
He was once again selected for the World Test XI at the 2005 awards.
Over a fifteen-year international career relatively free of injury, he has set a number of national and international records in wicket hauls and bowling figures.
As of 11 October 2016, only 3 bowlers have taken more ODI wickets than Vaas.
He is the youngest bowler to take 300 wickets in ODI cricket.
