The 23-year-old Delhi lad, who plays for the Railways U-25 side, recorded figures of 28.5-5-77-10 but his team lost the match by 10 wickets as the batsmen failed to score enough runs.
Thakur has been regularly training at the MRF Pace Academy and also had sessions with Aussie great Glenn McGrath.
"I have been fortunate to have interacted with McGrath sir a couple of times at the academy. He gave some invaluable tips on channel bowling and using the subtle variations. My strength is bowling out swingers," a beaming Karan told PTI over phone from Vadodara.
Asked when exactly did he think that he could get 10 wickets in an innings, Karan replied, "When I got the eighth wicket, I felt that I might get 10 wickets. It was a great feeling when I got the 10th victim. The umpires presented me with the match ball, a souvenir that I would like to treasure forever.
