Golf:Americans Tommy Gainey and Mark Wilson were tied for the lead at 11-under par when the second round of the frost-delayed Phoenix Open was suspended due to fading light.
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 on Monday.
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 yesterday, organisers decided to extend the tournament into a fifth day.
The second round will be completed on Saturday when the field will be cut, as usual, to the top 70 players. Officials plan to play until darkness for the next two days.
"We'll probably make the cut sometime tomorrow afternoon," said PGA Tour rules official Slugger White. "If it makes sense to start the third round (on Saturday), we'll try to do that.
"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 on Saturday and Sunday mornings.
"It's unbelievable how frozen these greens get, and they just don't thaw out," he added.
It will be the first Monday finish at the Phoenix Open since 1978. Thankfully, warmer, sunny weather is forecast for the weekend and also for Monday.
Gainey, who won twice on last year's satellite Nationwide Tour, 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."
