2012 Masters Leaderboard Update: Louis Oosthuizen Holds One-Stroke Advantage Through 12

It’s getting to crunch time in Augusta, and Louis Oosthuizen’s more or less consistent play through 12 has him up one on Peter Hanson.

Oosthuizen was able to par the par-3 12th, but Bubba Watson, who was just one shot off, pushed a putt from the fringe too far past the hole and now sits at 6-under, again two strokes off Oosthuizen’s lead. Hanson -- through 11 -- is the only golfer one stroke back.

There’s a bit of a pile-up on the leaderboard at six-under: Lee Westwood had back-to-back birdies on 13 and 14 and got on the green in two on the par-5 15 to put himself in contention. Ian Poulter birdied that 15th to get himself to 6-under, and Watson, Matt Kuchar and Phil Mickelson join them to round out the group within two of the lead.
