Mickelson, Harrington tied for Nissan lead

They both were 11-under-par at 131, three shots ahead of Charles Howell.
LOS ANGELES (AP) -- Phil Mickelson and Padraig Harrington spent Friday afternoon on opposite sides of Riviera as they played vastly different styles. All they had in common when the second round ended was a share of the lead at the Nissan Open.
Mickelson made only one bogey and got hot with his irons on the back nine with back-to-back birdies inside 5 feet and a 3-wood from 287 yards that set up an eagle on the 17th hole, sending him to a 6-under 65 and a chance to win for the second straight week.
Harrington only made two pars on his first 10 holes, a round filled with brilliance and bogeys, until he finally settled down in the twilight hours off Sunset Boulevard to polish off a 68.
They were at 11-under 131, three shots clear of Charles Howell III, who shot 65.
"Anything in the 60s was really the goal today," said Harrington, playing the Nissan Open for the first time. "I knew going out there I would be a little erratic. 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."
Hitting driver well
Mickelson hasn't played Riviera since 2001, and he only added this tournament to his schedule at the last minute to test the newfound confidence in his driver. Two rounds, he hasn't found any flaws.
"I like the way I put the ball in play," Mickelson said. "It feels easy."
He reached all three par 5s in two, none more impressive than the 17th. Coming off his only bogey of the tournament, when he pulled his tee shot into a back bunker on the par-3 16th, Mickelson hit a bullet of a tee shot down the left side of the fairway some 310 yards. He followed that with a hard 3-wood that drew slightly and found the middle of the green, rolling to 15 feet.
"I was just trying to get down there by the green in two," Mickelson said. "I still wanted to be left so I would have a good angle to the green, and I just flushed it. It came off perfect."
Near flawless performance
It was another command performance, similar to last week at Pebble Beach when he won by five shots. He only missed four fairways, but none of them were off the fairway by much, and he never had a problem going after the flag. The only glitch was a few irons that he pulled, but it only cost him a bogey on the 16th.
Mickelson finished his round with an approach that sailed right of the green, but a flop shot landed softly and trickled 4 feet below the hole, allowing him to save par and go into another weekend in the final group. The next quiz comes on the weekend, for Mickelson has made the cut only five times in nine tries at the Nissan Open, and he has never finished in the top 10.
"It's a good start for two rounds," Mickelson said. "But one of the best players in the world, Padraig Harrington, is tied for the lead. The greens are going to be firm. It's going to be hard to get the ball close to the hole. It's going to be a challenge."
