The Baylor School and Vanderbilt graduate claimed his first PGA Nationwide Tour victory, taking the South Georgia Classic Presented by First State Bank and Trust Company in Valdosta at 16-under par, two strokes ahead of Brian Stuard.
His rounds of 67, 68, 69, and 68 made him the only player to shoot in the 60's in all four rounds, and his score of 272 tied the tournament record. His previous best Nationwide finish this season came in early March when he tied for second at the Panama Claro Championship.
In seven events this season, List has three Top 10 finishes and three Top 25 finishes, having made the cut five times. He missed the cut in his previous tournament last week.
List, who began the tournament with back-to-back birdies, held a share of lead on both Friday and Saturday night and began Sunday tied for first with former PGA Tour winner Woody Austin, who finished five strokes back.
"It feels fantastic," List told PGATour.com after his win. "It's hard to describe. People always say it hasn't really sunk in yet and I think that's the case."
The Kinderlou Forest Golf Club course is the longest on the Nationwide Tour at 7,781 yards, but List, the longest driver on the tour, lived up to that title by averaging 329 yards off the tee with his longest drive of the week going a staggering 370 yards.
He hit 77.8 percent of the greens in regulation and 64.3 percent of his fairways. He also chewed up the par 5's, going 13-under par on them for the week.
"This course sets up so well for me, so I told myself coming in, 'just stay out of your own way and do your thing,'" he added. "I hit a lot of wedges where I could give myself those 15-20 footers. I never really felt stress out there as far as, OK, I'm not making as many putts as I'd like, but it's OK. I'm hitting it great. I'm giving myself a lot of opportunities. I can eat up the par-5s and hang on for the rest."
He began Sunday's final round with back-to-back birdies again before nine consecutive pars and a bogey on No. 12, the third bogey of the tournament for him on that particular hole.
But he rebounded with an eagle at the par-5 13th and a birdie on the 16th before two straight pars to win the title.
"I just kept telling myself this was my week. This is my turn. And I really believed it," he said. "I really felt like this is mine."
He earned $112,500 for the win, which moved him to No. 2 on the 2012 Nationwide money list with $175,448 this season.
If List finishes the season in the Top 25 on the Nationwide money list, or wins a total of three Nationwide tournaments this season, he will earn his PGA Tour card for the 2013 season.
