Tim Petrovic shot a career-best 8-under 63 at the TPC of Scottsdale to vault up the leaderboard. He's tied with first-round leader Harrison Frazar (67) at 13-under-par 129.
Frazar, who teed off in the afternoon, had four birdies and no bogeys.
Luke Donald (66), Steve Stricker (62), John Huston (67), John Rollins (66) and Scott McCarron (65) are tied for third place at 11-under.
Petrovic had no such downfall. After a bogey on his third hole ' the par-3 12th ' he made seven birdies and an eagle at the par-5 15th.
I was just trying to get the ball in play off the tee. I know Im putting well; I was just trying to hit greens and give myself some chances for birdie, Petrovic said. I just stayed patient, kind of waited for something to happen, and I got something going.
This is Petrovics second season on the PGA Tour, but hes far from a newbie.
The 36-year-old, who lists deceased Doors frontman Jim Morrison among his heroes, turned professional in 1988 after an All-America campaign at the University of Hartford. He struggled on various mini-tours over the years, but started to turn things around in 2000, when he was Player of the Year on the Golden Bear Tour.
Thanks to a seventh-place finish on the 2001 Nationwide Tour money list, he earned his card for the first time on the PGA Tour. Petrovic made 15 cuts in 31 starts in his rookie season, and tied for second in the FedEx St. Jude Classic en route to keeping his exempt status for this year.
Ive done every odd job the last 13 years. If anybody should appreciate it, its me, he said.
One of those odd jobs was being a baker and deliveryman at Pizza Hut, where he spent his breaks hitting golf balls in the parking lot.
Donalds path to the big leagues was much more paved. The 25-year-old Englishman was the 1999 NCAA individual champion at Northwestern University. Three years later he was a winner on the PGA Tour.
Donald captured the final event on the 2002 calendar, the Southern Farm Bureau Classic, when the final round was washed out.
The Hempstead native had five birdies Friday, and has a total of 11 without a bogey through two rounds.
The last couple of tournaments Ive played decently but Ive been making too many mistakes, Donald said. This week its been a different story. Ive been minimizing my mistakes and taking advantage of the birdie (opportunities) when I get them.
Stricker had plenty of birdie chances in round two. He was 10-under over his first 15 holes, but finished par-bogey-par.
