Adam Scott has already run through a whole spectrum of emotions through three holes Sunday, as he bogeyed the par-3 first hole, birdied No. 2 and wound up in a bunker on hole No. 3, leading to a bogey.
The Australian now sits at 10-under par, three shots ahead of Brandt Snedeker, who's at even par for the day. Tiger Woods also is even through five and lurks just four strokes back at 6-under par.
Graeme McDowell dropped an early shot to fall back into a tie with Tiger at 6-under, while Louis Oosthuizen is 1-under on the day and sits at 3-under par overall.
After a 3-over par 73 Saturday, Jason Dufner again is struggling. He's 4-over on the day and has dropped 19 spots thus far.
Weather should not be a huge factor Sunday -- it's pleasant and partly cloudy, with winds at 10-15 mph.
