Vinay Kumar is a seam and swing bowler who relies more on legcutters, slower balls and accuracy, than on outright pace. Making his first-class debut in 2004-05, he quickly established himself by taking more than 20 wickets in each of his first three first-class seasons. Vinay soon added the inswinger to his repertoire, and his consistency earned him an IPL contract with Royal Challengers Bangalore in 2008. His first defining domestic season was in 2009-10, where he captured 46 wickets, besides mentoring his fast-bowling colleagues, Abhimanyu Mithun and S Aravind, to lead Karnataka to the Ranji Trophy final for the first time in 11 years. Some good performances in IPL 2010 earned him a spot in India's squad for the World T20 in West Indies, but he has not been able to hold it down consistently. His most recent international appearance came in 2013.
