LOS ANGELES — Phil Mickelson seems to be everywhere.

This is his fifth consecutive week on the PGA Tour, which has taken him from Palm Springs to San Diego, from Phoenix to Pebble Beach. He warmed up for the second round of the Nissan Open by hitting balls about 3Z\x hours before he teed off Friday, which is not unusual except that Mickelson was at the Callaway Test Center in Carlsbad, and the tournament is two hours away at Riviera.

The one place he's easy to find is in the fairway — and atop the leaderboard.

Coming off a command performance at Pebble Beach, Mickelson put himself in position for a second straight victory with a 6-under 65 that gave him a share of the lead with Padraig Harrington, who had a 68.

They were at 11-under 134, getting there with vastly different styles.

Mickelson, with a reputation for going for broke and hitting shots that can go anywhere, again looked steady off the tee. He missed only four fairways, most of those in the first cut, and didn't make a bogey until the 16th hole on Friday. He followed that with two of his best shots that set up a 15-foot eagle putt.

"I just flushed it," he said of a 3-wood from 287 yards. "It just came off perfect."

Harrington, known for being steady from tee to green, scrambled like mad and made only two pars over his first 10 holes. He finally settled down from there and was pleased to post anything in the 60s.

"I knew going out there I would be a little erratic," Harrington said. "I'm still making mental errors here and there, so I put up with that. And I made some birdies to counteract some of the bogeys, which was very nice."
