Gavin Coles and Nick Flanagan were tied for the lead after yesterday's third round of the US Bank Championship.
Tied with Richard Johnson for the lead at the start of play, Flanagan carded a one-under-par 69 to move to 11-under-par 199 where he is joined by Coles, who signed for a two under 68.
Canadian Jon Mills, George McNeill, Ken Duke and Johnson are tied for third at 10 under.
Mills, who has a pair of Nationwide Tour victories on his resume, had seven birdies and just one bogey to jump into contention.
Chris Riley, Jason Gore, Patrick Sheehan, Brandt Jobe and Joe Ogilvie are at nine under with a group of 10 players at eight under.
The defending champion, Ogilvie bogeyed three of his first four holes but had three birdies on the back nine and finished with a two under 68.
Coles got off to a slow start with bogeys on his first two holes. He did not get going until the back nine, when he recorded all four of his birdies, including three in a five-hole stretch starting on hole 12.
"The weather was pretty bad when we first started," Coles said.
"It was coming down pretty heavy, it didn't seem heavy, but we were getting really wet and the ball was going nowhere.
"After that, the weather settled down and it was pretty easy after that. The course was there for some birdies."
Flanagan managed four birdies with three bogeys. After dropping a shot at the 17th, he rebounded to close the round with a birdie at the par-five 18th and gain a share of the lead while pursuing his first PGA Tour title
"I just bogeyed 17 and I knew 18 was kind of a little bit of an easier opportunity for a birdie and I hit a really good drive down there," Flanagan said.
"Had a perfect number for a big hybrid and hit it in there to about 12 feet. I thought I hit a perfect putt, not sure how I missed, but it was a birdie and retained a share of the lead."
