'It's called the fifth major, and nobody's ever shot 62 here,' Chopra said. 'The greatest players have all played here, and the course record would have been a feather in my cap.
'I was going for it, and I really wanted it.'
The course record is 63, shared by Greg Norman (1994, first round) and Fred Couples (1992, third round).
Chopra, who bogeyed the last two holes, had a chance at 8 under at his final hole (No. 9). He had his mind set on making an eagle to become the first player to shoot 62.
Chopra hit an errant drive, though, forcing him to lay up, then he chunked a wedge. His club flew out of his hands as followed through on his third shot, which ended up in a greenside bunker.
'It was a reflex action,' said Chopra, who shot 65 and stands at 4-under for the tournament. 'As soon as the club hit the ground, I knew what I had done.'
Chopra said he had a tight lie from 89 yards and decelerated trying to squeeze a shot into a front pin placement.
