Fulton Allem turned back Keith Clearwater's tournament-record 61 and took a one-stroke lead over him Friday in the storm-delayed second round of the Colonial Invitational at Ft. Worth.
Allem birdied the final hole from 25 feet to cap a 63 and set a tournament record of 11-under 129 for the first 36 holes.
Clearwater birdied the last seven holes en route to a course and tournament record.
Beginning on the 12th hole, he had birdies from 20, 25, 45, 12 and four feet, a tap-in from inches after a wedge on 17, and then closed the round with a 40-footer.
"Conditions were absolutely perfect. They couldn't have been better," Clearwater said.
His score has been bettered only 10 times in the history of the American tour, 59s by Al Geiberger and Chip Beck and eight scores of 60.
Gary Evans shot a six-under 66 to take the first-round lead in the European PGA at Virginia Water, England.

Arnold Palmer struggled to a 78. His tee shot at 17 beaned a spectator, who was not seriously injured.
Kelly Robbins had two eagles for a four-under 68 to take sole possession of the lead after two rounds of the LPGA Corning Classic at Corning, N.Y. Robbins has a 36-hole total of 138, one stroke ahead of Hiromi Kobayashi.
