Wait, Roberto who? 

Yes, Roberto Castro tied the course record at TPC Sawgrass on Thursday morning with a 9-under-par 63 to take a commanding lead at the 2013 Players Championship.

Castro now shares the record with Fred Couples (third round in 1992) and Greg Norman (first round in 1994). 

He had a 13-foot putt on the final hole to shoot a 62 and set the course record, but he missed it just right of the hole before hitting his comeback four-footer to tie the record.

Here's a look at his absurd scorecard, which included exactly zero bogeys:

And here are the lengths to the hole of his absurd approach shots:

After his round, Castro told Golf Channel he wasn't aware he was putting for the course record on his last hole:

"I kind of figured the putt on the last hole was for something good. Sixty-two seemed like it would be tied or the course record but I didn't know."
