Phil Mickelson is seeking his fourth career victory at Torrey Pines, where he's making his season debut this week.

MICKELSON UPDATE (4:50 p.m.): Phil Mickelson's day was the definition of what you call an up-and-down one with five birdies and three bogeys. Mickelson hit 57 percent of his fairways and didn't make much with the putter, taking a less-than-pedestrian 33 putts after hitting 78 percent of his greens in regulation. Add it all up and it's a round of 2-under 70. On the bright side, at least that number came on the South Course. If he'd shot that on the North Course, he'd be in trouble. It also marks the third-straight year Mickelson has opened with a 70 here. Last year, he finished in a tie for 42nd. In 2008, he tied for sixth.
