Udana is a talented left-arm fast-bowling allrounder. While still a schoolboy, at DS Senanayake College, he joined Nondescripts CC, but even before he could represent them in a domestic match he was selected to play for Sri Lanka

Under-20 Schools side in the ongoing U-23 Division I youth tournament. He was selected to tour South Africa with the Sri Lanka A team in August 2008 without having played a single first-class match. He was later fast tracked into the Sri Lanka squad for the ICC World Twenty20 in England the following year.

He effectively varies his pace, making him an effective Twenty20 bowler. He was the leading wicket-taker in the Inter-Provincial T20 tournament in 2008-09, helping Wayamba to the title and a berth in the Champions Twenty20 League.
