Patrick Rodgers carded an nearly flawless seven-under-par 64 to take a two-shot lead at the John Deere Classic after two rounds.
"I'm starting to drive it nice so I'm giving myself a lot of wedges from the fairways and able to make some birdies", said Rodgers.
"I've got plenty of time to win tournaments".
Rodgers mixed eight birdies with a sole blemish in an impressive display at TPC Deere Run, lifting him two clear of nearest challenger Bryson DeChambeau.
The 25-year-old is yet to secure his first PGA Tour victory, yet a seven-under-par 64 in IL saw him take a two-stroke buffer over fellow American Bryson DeChambeau.
Former Open champion Zach Johnson joins overnight leader Charles Howell III in a share of third on 10 under, with Kevin Tway part of the group a further stroke back after a round-of-the-day 63.
Howell, playing for a third consecutive week after returning from a 10-week layoff for a fractured rib, booked a spot in next week's British Open with his latest second-place effort.
On Friday, though, he caught fire after a slow start, nailing a 50-foot chip-in for birdie at his 12th and a 50-foot birdie putt four holes later.
Rodgers, who has played this event more than any other on the PGA Tour, has missed the cut in 13 starts this season, but has reached the weekend in his last three starts.
China's Feng Shanshan fired a bogey-free six-under-par 66 Thursday to grab a one-stroke lead over South Korean Amy Yang early in the opening round of the US Women's Open. Finishing on the front nine, he had five birdies in a seven-hole stretch before closing with a bogey on the par-4 ninth.
