Brett Quigley held a two-shot lead at the Buick Open just after the turn, and his mind drifted to an easy stretch of Warwick Hills.
A couple holes later, a huge oak tree taught him a lesson.
Quigley scrambled to save par at No. 13 -- the second-easiest hole -- and that contributed to him losing the lead yesterday and finishing the second round in a three-way tie with Jim Furyk and Kenny Perry at 10-under-par 134 in Grand Blanc, Mich.
"I tried to force the issue," Quigley acknowledged. "I knew if I could make four or five birdies, I might have a pretty good lead. As a result, I started thinking about results instead of staying in my process and got ahead of myself and came back to the field."
Quigley (69) and Furyk (68) had solid rounds after starting the day among the leaders while Perry's 9-under 63 lifted him from a tie for 73d.
First-round leader Rocco Mediate (71), Scott Verplank (69), and Brian Bateman (70) will start the weekend only one shot behind the leaders, a negligible difference on a course ripe for low scores.
Perry was the latest golfer to prove that.
The 2001 Buick Open champion birdied five of his first seven holes, one-putted his first eight, and was 10 under through 17. He pulled his final tee shot, forcing him to chip onto the fairway, and missed a 17-foot par putt to fall into a tie with Furyk and Quigley.
Perry matched his low round of the season. His last 63 closed the Memorial earlier this month, helping him finish third for his only top-10 finish since 2005. He was a season-best 11th last year at the Buick Open.
Perry's wife went to the hospital Wednesday because of food poisoning, and on Thursday, he plunked two fans -- shattering a woman's nose and hitting a man's shoulder.
"I don't know what to make of it," he said. "It's been an interesting week so far."
Tiger Woods and Vijay Singh are not playing the Buick Open for the first time since 2001, giving more players a shot at an $882,000 check.
Woods (with his wife and baby) and Singh (resting a sore elbow) have combined to win four of the previous five tournaments here.
Champions -- Loren Roberts had his low round of the year, a 7-under 64, to take a one-stroke lead over Eduardo Romero after the first round of the Commerce Bank Championship in East Meadow, N.Y.
A powerful thunderstorm passed right over the Red Course at Eisenhower Park Thursday night, damaging a few trees and knocking down a scoreboard and hospitality tent just behind the 18th green. Crews worked through the night, and yesterday's round got off on time.
"They did a remarkable job of getting the course in shape. It didn't even look like it rained," Roberts said of the county-owned facility. "Those guys must have worked their tails off last night."
Roberts made the turn at 2 under, but he had five birdies in his last eight holes to better his yearly average by almost five strokes. Roberts, who is tied for the Tour lead in putting average at 1.706, needed only 29 putts and reached all but one green in regulation.
Romero had a solid day with his irons -- the longest of his six birdie putts coming from 7 feet.
European -- Simon Khan shot a 4-under 67 (5-under 137) to take a one-stroke lead over Paul McGinley (69) and Colin Montgomerie (70) after the second round of the French Open in Versailles.
Portland Open -- Jim Renner of Plainville birdied five of his final seven final holes en route to a tournament-best 63 (16-under 197) to grab the top prize by two shots over Justin Goodhue of Glastonbury, Conn., in the 54-hole event in Maine.
