Tiger On The Prowl At U.S. Open

Even with a sore knee, Tiger Woods hit his stride in the second round at the U.S. Open.

Woods had five birdies during his final nine holes in his round of 3-under 68 at Torrey Pines that left him one shot behind Stuart Appleby going into the weekend. Woods is tied with Rocco Mediate and Robert Karlsson, who are also at 2-under for the tourney.

Appleby holed a 45-foot birdie putt on the 18th hole for a 70 that put him at 3 under par. Appleby has the lead in a major for the first time since he led Woods by one shot going into the final round of last year's Masters.

Appleby was at 3-under 139 and will play in the final group withMediate on Saturday. Mediate reached 4 under at one point before settling for a 71.

Woods will play with Robert Karlsson, who shot a 70.

Local favorite Phil Mickelson, who has never won a U.S. Open, had a long day. He shot a 75 to go 4 over for the tourney, seven shots off the lead.
