Brett Quigley enters Sunday's final round of the $2 million Ally Challenge in Grand Blanc, Mich., with a one-stroke lead over Jim Furyk, Carlos Franco and first-round co-leader Tommy Armour III.
Quigley carded an 8-under-par 64 in Saturday's second round at the Warwick Hills Golf and Country Club, moving to 11-under 133 for the tournament. He has 12 birdies and zero bogeys over his last 35 holes.
"I wanted to get close," Quigley said. "I figured if I get within one or two groups of the last group, that was the goal going in today."
This is the first PGA Tour Champions event since early March, ending a hiatus caused by the coronavirus pandemic.
Furyk, who turned 50 on May 12, fired a bogey-free 66 on Saturday to get to 10 under. He is trying to become the first player to win his Champions debut since Miguel Angel Jimenez in 2014.
"It's been fun," Furyk said. "It's been great to be back at a golf course that I always enjoyed playing when we were here on the PGA Tour, and great to see some old friends."
Franco made two eagles during his round of 8-under 64, at the par-5 seventh and 13th holes. His previous best round, in relation to par, was a 7-under 63 at the 2016 Shaw Charity Classic.
Armour's bogey-free round of 68 included birdies on two of the first four holes. He got into the tournament as the first alternate when Brandt Jobe withdrew on Tuesday.
First-round co-leader Billy Andrade dropped into a tie for 32nd after a 2-over 74.
Glen Day (66 on Saturday) is in fifth place at 9-under, while Woody Austin (68) and Wes Short Jr. (69) are tied for sixth at 8-under.
