Brett Quigley birdied six of his final seven holes on Friday to cap a round of 9-under 64 and take a one-shot lead after one round at the Cologuard Classic in Tucson, Ariz.
Quigley, 50, won his first Champions Tour start at the Morocco Champions earlier this month. His scorching finish Friday at Omni Tucson National's Catalina Course left him a stroke ahead of Sweden's Robert Karlsson, who was alone in second place with a 65.
Four players are tied in third at 6 under: John Daly, Steve Stricker, Glen Day and Australia's Rod Pampling. Another stroke back are Bernhard Langer of Germany, Fred Couples and Ken Tanigawa.
Quigley opened strong with three birdies in his first five holes. Then, after six straight pars, he added four birdies in a row starting at No. 12, then birdied 17 and 18 to cap a bogey-free round.
"Hit some good shots and made some good putts, and all of a sudden it was a bunch of birdies," Quigley said of the late surge.
Karlsson had an up-and-down start, opening with a bogey before making eagle at the par-5 second. He tacked on two more birdies at Nos. 3 and 4 before a bogey at the fifth.
After another birdie at No. 8, Karlsson shot a bogey-free, 5-under 32 on the back nine.
Daly had his own hot streak, notching six birdies from Nos. 2 through 5, then Nos. 7 and 8, but cooled off from there. He played his final 10 holes at even par, with one birdie and one bogey.
Stricker, the 2018 champion, was bogey-free with six birdies, while Couples had an eagle, four birdies and one bogey. Langer collected eight birdies but made three bogeys.
Defending champion Mark O'Meara shot 69 and is among eight players tied in 10th.
