Frost forces fifth day for Phoenix Open

Nationwide Tour graduate Gainey was three-under for the round after nine holes and Wilson five-under after 14 when play was halted for the day at TPC Scottsdale where the protracted tournament will finish tomorrow.

Australian Geoff Ogilvy, a Scottsdale resident, was alone in third at nine-under with two holes to play, a stroke in front of twice champion JB Holmes and Jason Dufner.

The big-hitting Holmes, winner here in 2006 and 2008, had completed 12 holes while fellow American Dufner had seven remaining.

With four hours of play lost on Thursday because of heavy morning frost and a further 94 minutes wiped out on Friday, organisers decided to extend the tournament into a fifth day. The second round was scheduled to be completed yesterday when the field was to be cut, as usual, to the top 70 players.

Gainey, who won twice on last year's satellite Nationwide Tour and is known for his two-gloved grip, was delighted to be at the top of the leaderboard after not making a cut in three previous PGA Tour starts this season.

"I'm starting to hit the ball like I'm supposed to, I'm starting to score," he said. "Putts are dropping... once the putts start falling, you can shoot an unbelievable low number.

"It just so happens that I'm making putts right now, and I'm tied for the lead."

PGA Tour rules official Slugger White said: "In a perfect world, we'll probably finish Monday (with] maybe four or five holes (to play], best-case scenario."

White said a great deal depended on how much further time was lost because of possible frost delays.

"It's unbelievable how frozen these greens get, and they just don't thaw out," he added.

Warmer, sunny weather is forecast for today and Monday.
