Born August 17, 1975 in Kadugannawa, Ratnayake is the epitome of Sri Lankaís boxing revival in the post 2000 era.

A member of the Slimline Boxing Club, Ratnayake was educated at Peradeniya Central College and has been a national champion since his school days. A consistent performer at the SAF Games, he has won three silver medals at the SAF Games to date. He was unfortunate to miss out on medals at the Manchester Commonwealth Games and the Commonwealth Championships in Malaysia when he lost to the eventual Gold medalists.

Fighting in the flyweight category, Ratnayake compensates for his inherent lack of height and reach by sheer grit, determination and strength that have seen him overcome considerable odds during his long tenure within the international boxing circuit. He returned to the sport after a two year lay off in September 2007, striking with immediate success when he knocked out his Tanzanian opponent at the historic Sri Lanka vs. Tanzania Dual Championship
held in Colombo.

Building on this success, Ratnayake went on to great heights by qualifying for the Beijing Olympics in 2008, ranking amongst the top 8 in the world at the AIBA World Championships held in Chicago in October 2007. He is the first Sri Lankan boxer to qualify for the Olympics after a lapse of 40 years, and is also the first Sri Lankan pugilist to have gained the right to compete at the Olympics through the qualification system. Now a household name and one of the biggest sporting stars in Sri Lanka, Anuruddha remains one of the islandís best medal prospects in Beijing this year.
