The opening round of the 2012 Masters is in the books, and there's a familiar face sitting alone atop the leaderboard. Lee Westwood, who ended Tiger Woods' reign as No. 1 golfer in the world in 2010, leads the field after shooting a 67, which is good for -5.
Louis Oosthuizen sits alone in second place after shooting a 68 in the opening round. Oosthuizen went into the clubhouse as the leader with his -4, but would soon be ousted by Westwood.
Tiger Woods, who is looking to continue his comeback, finished the day even par after shooting a 72. Woods was sitting at -2 headed into the 17th hole, but bogeyed the last two holes to finish the day even par.
