He played as an attacking slow left arm orthodox bowler and left-handed tail-ender batsman for Hyderabad.

[1] Ojha's earliest pursuit in cricket was at the age of 10, when he went to the Saheed Sporting Club for a summer camp in Bhubaneswar under Sasang S Das, while studying at D.A.V.

[2] Four years later, he moved to Hyderabad to pursue studies[3] and chose cricket as his profession under the guidance of his coach T. Vijay Paul.

His high success in the first couple of seasons in domestic cricket and the IPL ensured his selection in the 15-man Indian squad for the Bangladesh tour and Asia Cup in 2008.

He has performed exceedingly well in the six editions of IPL, earning him the praise of his captain Adam Gilchrist and Sachin Tendulkar.

In November, during the First Test of the West Indies Tour of India he staged a marvelous comeback taking 6 wickets for 72 runs in the first innings.

In December, 2014 Ojha was barred from bowling in competitive cricket after his action was found to be illegal.

In a 2008 interview, Ojha said that Venkatapathy Raju, who was also a left-arm spinner, inspired him to play for India.
