The 22-year-old, who is yet to achieve prominence here, has grown in confidence after he got his "biggest breakthrough" in the academy last year.
"It was the biggest breakthrough in life. Facing quality bowlers was great experience. 12 out of 14 bowlers practicing there were from different the IPL teams. I have been invited to another bowling camp starting from June 14. I am eagerly waiting for it," Digvijay told PTI in an interview.
Batting at number four, Digvijay enjoyed moderate success, scoring 138 runs in the four matches, but the exposure of rubbing shoulders with Sri Lanka's national players was the highlight for him.
"I took the opportunity for exposure and it turned out to be fantastic. Surprisingly, pitches in Sri Lanka had pace and bounce and their pacers were bowling fast on those supportive pitches.
"Though conditions were tough, I enjoyed playing Lankan bowlers. I guess being a backfoot player helped me," Digvijay, son of Surinder Amarnath, said.
