Louis Oosthuizen is the leader after three rounds of the 2012 Deutsche Bank Championship, holding a three-stroke advantage over second-place Rory McIlroy.
Oosthuizen played a magnificent round of golf on Sunday, shooting an 8-under 63, which was tied him with Keegan Bradley for the best score of the day. Oosthuizen, a South Africa native, is at 19-under for the tournament after the solid effort, and hasn't shot worse than a 66 in any of the first three rounds.
