Steve Flesch holds a two stroke lead at the halfway stage of the Reno-Tahoe Open, after a three under par round of 69 on Friday.
The overnight leader, who missed out on the course record by one shot when firing an opening 63, is 12-under par for the tournament.
Charles Warren matched Flesch's earlier effort to surge into second place, making seven birdies and an eagle, while Argentina's Jose Coceras sits in third two further back.
Flesch had six birdies to offset a bogey and a double-bogey, but says the weather conditions affected his game.
"I just like playing here," said the 40-year-old. "For some reason I've had success on this golf course.
"Obviously, I just hung in there today as the wind got blustery. It was a lot different than Thursday's round."
Elsewhere, Hawaiian 16-year-old Tadd Fujikawa failed to make the cut of 144 on his professional debut, but said he took plenty out of the two days.
"I learned a lot, especially at this level of play. It's not like you can make stupid mistakes," he said.
"You can't just go out there and hit balls in the rough and I didn't get off to a good start.
"But I brought it back and got things going to finish one under. I'm going to take a lot from the experience."
