Aaron Wise joined Marc Leishman atop the leaderboard following the third round of the AT&T Byron Nelson.
Leishman and Wise are four strokes clear heading into the final day following respective rounds of 69 and 68 in Dallas on Saturday.
Wise understands winning. He was the first player since Kevin Chappell (2008) to win both the NCAA individual and team national titles in the same year (2016), and now he is in position for his first career PGA Tour win.
The 21-year-old – who posted rounds of 65 and 63 to open the tournament – had six birdies and three bogeys as he moved to 17 under through 54 holes at Trinity Forest Golf Club.
"I think I put a little bit too much pressure on myself early, I turned in two under, which I thought was a little bad because the front nine is what you need to get around here," Wise, who was the youngest player to make the cut at the event, told CBS Sports after his round.
"But taking that aside I felt like I did great on the back nine, finished it in three under which is a great round today."
Leishman, who took a three-shot lead after a career-low 61 in the first round, is looking for his fourth career PGA Tour win and first since the Arnold Palmer Invitational in 2017.
The Australian went two under in very windy conditions – Leishman tallying three birdies and a solitary bogey.
"Very different conditions today than what it was Thursday afternoon," he told CBS Sports. "The course was firming up, a lot windier, and a different situation, a few more people out there today, so I'm really, really happy with the way I played today after a really slow start."
Fellow Australian Matt Jones is tied for third with Kevin Na (69) at 13 under after a bogey-free 68, while Jimmy Walker (70) and Brian Gay (72) are a stroke further back.
Elsewhere on the course, three-time major champion and former world number one Jordan Spieth ended the penultimate round tied for 29th and 10 shots off the pace.
Spieth dropped the leaderboard following his 71, which included two bogeys from his opening three holes.
