The former Vanderbilt player finished at 16-under 272 at Kinderlou Forest, and earned $112,500.
"It feels fantastic," said List, surrounded by his parents, grandparents and girlfriend. "It's hard to describe. I really put my head down, especially on the weekend. I knew where I was all day and it was nice to perform under the pressure. Hopefully, this will be a turning point for me and I can get a few more this year."
Stuard finished with a 66. Three-time PGA Tour winner Woody Austin, tied for the third-hole lead with List, had a 73 to drop the third, five strokes back.
List averaged a field-best 329 yards off the tee on the 7,781-yard course, the longest on the tour.
"This course sets up so well for me that I just told myself to stay out of your way and do the right things," List said. "Out here with my length I just had so many opportunities. This is a long course but I had a lot of wedges where I could give myself those 15- to 20-footers. I never felt stressed out there."
