Steve Flesch birdied the final three holes to take a one-shot lead at 11 under after Saturday's second round of the American Family Insurance Championship at University Ridge Golf Course in Madison, Wis.
Flesch followed up his opening-round 68 with a 7-under-par 65, tied for the best round of the day. He hit 17 of 18 greens in regulation and will start Sunday's final round as a leader or co-leader of a PGA Tour Champions event for the first time.
"I had last week off. I didn't play any golf, didn't hit any shots. I was doing the Fox coverage for TV for the U.S. Open, so I didn't even have my clubs with me," Flesch said.
"I flew home from there and didn't even fly up here until Wednesday, so I had a nice week and a half off from playing any golf, although I was immersed in maybe the biggest championship going on in the world. Learned a lot from those guys just watching Brooks Koepka ... and how they go about it. I think I was getting a little too worked up putting pressure on myself playing."
The left-handed Flesch was 5 under on Saturday's back nine to edge ahead of a trio of players at 10 under, including tournament host Steve Stricker, who has consecutive rounds of 67 in his hometown event. Stricker pitched in for eagle on the par-5 16th.
"I'm in position to try to win this tomorrow and that's a good feeling," Stricker said. "There's a lot of guys bunched up there, though. I imagine somebody's going to come out of that pack with a good round."
Billy Andrade (66) and Duffy Waldorf (67) were the others at 10 under.
Three players were tied for fifth at 9 under -- Retief Goosen (66), Tom Pernice Jr. (67) and Madison native Jerry Kelly, who was the first-rounder leader by a stroke after shooting a 65 on Friday. He had three birdies and a bogey Saturday for a 2-under 70.
Woody Austin was three shots back of Flesch, while John Daly (69), Kirk Triplett (70) and Australia's Stephen Leaney (68) were four shots off the pace, tied for ninth.
Defending champion and Charles Schwab Cup leader Scott McCarron shot a second-round 67 and was tied for 12th at 6 under.
Hall of Fame baseball pitcher John Smoltz shot a 6-over 78 on Saturday and was last in the 78-player field at 10 over. He received a sponsor's exemption to play in the event.
