Gotterup made his latest memory by shooting a nine-under-par 62 on Sunday to capture the John Deere title when Ben Kohles had a late mishap at TPC Deere Run in Illinois.
"It's always the goal to come out here and try to win," Gotterup said.
"I really like this tournament. They've been so nice to me."
Gotterup played this tournament on a sponsor's exemption in 2022, tying for fourth place in his first notable result on the PGA Tour. Now, he has something better.
Gotterup rose from 12th at the beginning of the final day to finish at 20-under 264 and win on the PGA Tour for the fifth time, including three triumphs this year.
Kohles, who was in the final threesome and tied atop the leaderboard, hit his approach shot on No.18 in the greenside pond.
After a penalty stroke, he took a double bogey.
"I'm proud of the way I played. I played awesome all week," Kohles said.
"Obviously sucks to just have that happen on the last hole."
Max Homa (64 on Sunday) was the runner-up at 19 under.
"I had a good chance to catch him," Homa said.
"He just played better. ... I had my chances. I just needed to be a little sharper."
Australian Karl Vilips finished at 10 under in a tie for 39th.
