In Sunday's final round of the 2012 Masters in Augusta, South African golfer Louis Oosthuizen holds a slim one-stroke lead and sits at 10-under through 15 holes.
Oosthuizen had a big double-eagle on the second hole but was unable to extend a big lead throughout the remainder of his front nine. He has put together a pair of birdies in his back nine thus far, including a birdie on 15 to once again move one stroke ahead of Bubba Watson, who is at 9-under. Matt Kuchar had briefly tied Oosthuizen at 9-under, but bogeyed on hole 16 to fall two strokes off the lead.
Watson and Kuchar keep coming on late in the round, so it may come down to Oosthuizen maintaining his pace and hoping the challengers run out of time and opportunity.
