Phil Mickelson watches his tee shot on the second hole during the third round of the Northern Trust Open.

LOS ANGELES — One shot clipped an ash tree and kept Phil Mickelson out of worse trouble than he was in. Another landed behind a Bottle Brush, blocking his path to the 10th green at Riviera. On yet another hole, Mickelson had to thread a 9-iron through the limbs of five eucalyptus trees.

So when he walked into the gallery to find his tee shot on the 15th and saw a man flat on his back, Mickelson assumed the worst. Instead, the fan was being still because the ball was in the hem of his shorts.

Despite all these adventures, Mickelson managed a 1-under 70 on Saturday to share the lead with PGA champion Keegan Bradley in the Northern Trust Open.

Bradley took only five putts over the last five holes, including a 10-footer for par on 18 that got him into the final group, for a 66 and his best chance at a win since he captured the PGA Championship in August.

Mickelson and Bradley were at 7-under 206, one shot ahead of Pat Perez (70), Jonathan Byrd (69) and Bryce Molder (66). Mickelson wasn't the only player on a wild ride along the fabled course off Sunset Boulevard.

Molder one-putted the last eight greens, five of them for par. Perez three-putted from 10 feet on No. 3, and on the next hole took four putts from 60 feet on the fringe, the last three from inside 5 feet.

LPGA THAILAND: At Chonburi, Thailand, Ai Miyazato shot a 7-under 65 to take a one-stroke lead over top-ranked Yani Tseng after the third round.

ACE GROUP CLASSIC: At Naples, Fla., Kenny Perry shot a 10-under 62 and break the Champions Tour's 36-hole scoring record with an 18-under 126 total in the ACE Group Classic.

Perry broke the record of 17 under held by six players.

NEW ZEALAND WOMEN'S OPEN: At Christchurch, New Zealand, 14-year-old amateur Lydia Ko shot her second straight 3-under 69 for a share of second-round lead.

Ko, the world's top-ranked amateur, became the youngest winner of a professional tour event last month in the Women's New South Wales Open in Australia.
