Rickie Fowler, who won the HSBC Abu Dhabi Golf Championship last month, shot a second straight bogey-free four-under par 66 at PGA National and through 36 holes of the Honda Classic is the sole leader.
"The putting's been good. I've been making putts," said Fowler. "Been playing well while I've been at home. I hit a lot of my lines. Some of it was a little bit of speed. I hit a couple that were just a little bit firm with where I was trying to play them. Other than that, I was starting putts where I wanted to, so that's the big thing, dialing in reads and speed."
Jimmy Walker trails Fowler by one stroke at seven-under, shooting a four-under 66 in the second round. He eagled the last hole to jump into sole possesion of second place.
Sergio Garcia, the first-round leader, shot a one-under 69, but fell two shots out of the lead and into third place.
After shooting a one-under par 69 in the first round, Phil Mickelson posted a four-over 74 on Friday. He fell into a tie for 60th place, 11 shots off the lead.
Rory McIlroy, meanwhile, shot his second straight two-over 72 and missed the cut by a stroke, the second straight year he's missed the cut in the Honda Classic.
Hideki Matsuyama, the winner of the Waste Management Phoenix Open three weeks ago, withdrew prior to the second round citing a right hip flexor injury. There is no immediate word on whether he will play the WGC-Cadillac Championship next week at Doral.
