After a string of 10 straight pars, Phil Mickelson ran into trouble on the back nine and dropped out of the lead at the U.S. Open. Mickelson is now in a tie for fourth place with Billy Horschel, Steve Stricker and Justin Rose now tied for the lead.
The trouble for Mickelson began at No. 12 when his par putt lipped out leading to his second bogey of the day. The bogey was Mickelson's third of the tournament to that point, all three of which were three-putt bogeys. The trouble continued on the next hole as Mickelson sailed a wedge on the 123-yard Par 3 over the green into a bunker. The ball plugged in the bunker, leaving him without much of a shot. Mickelson's bunker shot skipped over the hole, but he was unable to make the 12-foot par putt, dropping him to even-par for the tournament.
While Mickelson ran into trouble on No. 13, Stricker birdied the hole to join Rose and Horschel in a tie for the lead. Stricker is 2-under on the round through 14 holes. Rose temporarily dropped back to even par with a bogey on No. 6, but he moved back into the red two holes later with a birdie at No. 8.
Amateur Cheng-Tsung Pan, who plays college golf for Washington, has been one of the biggest risers on Friday. He's 2-under through five holes, joining Mickelson in the group tied for fourth place at even par.
