Brett Quigley and Gavin Coles shared the lead after two rounds of the Houston Open, one stroke in front of a four-man group that included defending champion Vijay Singh and John Daly.
Singh held a one-stroke lead after his opening 64, but had a 1-under-par 71 yesterday that included a bogey at the par-5 ninth that snapped a string of 64 holes at par or better at Redstone Golf Club in Humble, Tex.
Quigley shot a second straight 67 and Coles had a 69 to share the lead at 10-under 134.
Jeff Maggert (68) and Joe Ogilvie (67) joined Daly (67) and Singh at 135, while Greg Owen was another stroke back after a 69.
Jose Maria Olazabal (67) and Mark Calcavecchia (68) were in a group of five at 137.
Coles shook off a bogey on his first hole, the par-4 10th, by making a 65-foot birdie putt at No. 11. He had birdies at Nos. 14 and 15 and took the lead at 10 under with a 19-foot birdie putt on 18. After five straight pars, he birdied the par-5 sixth, then gave it back on the following hole when his 10-foot par putt ran 2 1/2 feet by the cup.
"You just never know which is your week," said the 5-foot-4 Australian, whose best finish this year is a tie for 17th at Tucson in February. "It's only Friday. I don't like to get ahead of myself too often."
Coles is making his second try at the PGA Tour. He made the cut in only seven of 28 events two years ago, finishing 227th on the money list. He played last year on the Nationwide Tour and was 20th in earnings with one tournament win and two top 10s.
Quigley had made the cut in nine of 10 events this year and finished in a tie for fourth at the Honda Classic. He's still looking for his first victory since becoming a regular on the tour in 1997.
"It's the ultimate goal," he said. "I don't know what else to say."
Quigley had seven birdies in his round, including a 25-footer at No. 15.
"Today was pretty ugly but I managed it," he said. "The goal is making putts at the right time, and I certainly did that today."
Singh, who earlier this week was selected for induction into the World Golf Hall of Fame, birdied No. 6, had the bogey at No. 9 and then reeled off nine straight pars.
