Louis Oosthuizen is one stroke off of Rory McIlroy's lead at the Deutsche Bank Championship at TPC Boston, as the South African has shot 6-under through 15 holes on the second day of the event.
Earlier today, McIlroy took the overall lead from Seung-Yul Noh, after shooting 6-under par on the day to improve to 12-under on the weekend.
Oosthuizen has had a very successful Saturday, shooting five birdies, an eagle, and a bogey to jump from eighth to second overall.
Also shooting 6-under on the day are Charl Schwartzel and D.A. Points. They, along with Noh, Tiger Woods, Chris Kirk and Jason Dufner, are tied for fourth.
Of that group, Woods still has a few holes of left to play today, as he is through 15. A good finish to his Saturday could put Woods himself in a tie with Oosthuizen or McIlroy.
