Louis Oosthuizen has held the lead at the 2012 Masters since his albatross on the front nine on Sunday. He's also holding it on the back nine because of some clutch putting.
Oosthuizen headed to No. 15, a par-5, with Matt Kuchar tied with him at 9-under. And he had a chance to add two strokes to his advantage after a superb tee shot. But his approach was mediocre at best, forcing him to deal with a mess and settle for a birdie putt. Oosthuizen sinking that one to move to 10-under on the day felt almost like saving a stroke.
Kuchar fell out of second place with a bogey on No. 16 moments after Oosthuizen's birdie, but Bubba Watson stayed on his playing partner's heels by cleaning up a disappointing eagle putt with a birdie. Watson is now at 9-under after 15, and Kuchar 8-under after 16.
Elsewhere, Lee Westwood finished a stellar back nine in 32 strokes with a birdie on No. 18, and headed to the clubhouse as the leader at 8-under after his Sunday 68.
