Oosthuizen is at 8-under for the day, tying him with American Keegan Bradley for the best score on the course on Sunday. Meanwhile, McIlroy, who was the leader heading into the day, has dropped into second place, as he is three-under through 14. Oosthuizen, who is at 19-under for the tournament, blazed through the front nine on Sunday with a performance that commentator Johnny Miller said was one of the best that he has seen.
Dustin Johnson, who finished six-under on the day, is in third place at minus-13 overall. Tiger Woods hasn't been able to keep up with the blistering pace of Oosthuizen, though he is still under-par for the round at minus two through 15 holes, and sits in fourth place overall. Bryce Molder, who shot three-under on the day and is at minus-13 through day three, rounds out the top five.
