Yadav was signed by the Mumbai Indians (MI) in the Indian Premier League (IPL) ahead of the 2012 season. He played just one match and was dismissed without scoring. In the 2014 IPL auction, he was bought by the Kolkata Knight Riders (KKR) for ₹7 million (US$82,000).

Yadav is a hard-hitting middle-order batter. He has a tendency to go all-out from the first ball, rather than take time to settle at the crease. He plays a wide range of shots and all around the ground on both off and leg sides. He uses his wrists to play shots around the ground and is often called Mr. 360 for his range of shots including scoops over fine leg.
