Patel, who had got all of India's four wickets on Day 1, got six more wickets to become the first New Zealand bowler to grab a 10-for in an innings. Patel's figures of 10 for 119 is now the best-ever by any bowler in India.
"Honestly, it's surreal and to be able to do that in my career is pretty special. The stars have aligned for me to do it in Mumbai," Patel said after his feat.
"Quite a special occasion for me and not just me but my family. Unfortunately for me, they're not here because of COVID. I'm in very illustrious company with Kumble sir as well."
Asked which scalp out of the 10 was special, he said, "Not anyone in particular and just trying to be repetitive and ask questions of batters.'
At stumps on Day 2, India reached 69 for no loss in their second innings, enjoying a lead of 332 runs.
