Watch: Cink's ace leads St. Jude Round 3 highlights

The round belonged to Andrew Putnam and Dustin Johnson, who both tore up the course in Memphis on Saturday and ended the day sharing the lead at 15-under par. However, Stewart Cink's ace on the par-3 eighth was most definitely the shot of the day.

Fourth-round action gets underway Sunday morning, with Putnam and Johnson teeing off in the final pairing at 12:40 p.m. local time.
