Fielding, of St. George, fired a three-round total of 14-under-par 202 at East Bay Golf Course and won the event on Saturday by two shots over Ogden pro Davis Garner, pocketing the $3,000 first-place check. Former BYU golfer Clay Ogden was third at 9-under 207.
Ogden's brother, current BYU golfer and defending State Amateur champion Cole Ogden, was the low amateur for the second straight time and third time in four years with a 209.
Two-time defending champion Tony Finau is No. 29 on the Web.com Tour money list and did not return to defend his title although there is no event this week, opting to rest up for a stretch of 14-straight weeks on that tour.
Garner and Fielding dueled all day Saturday after starting the day at 8-under, but Fielding took control for good with a birdie on the par-3 17th hole while the former Weber State golfer was making a bogey and finished with a 66.
"Probably the main thing was my putting was good all week," Fielding said. "For sure, the short game is kind of what did it for me."
Kai Ruiz, the 17-year-old Maple Mountain High senior who has committed to play for BYU, also started the day with a piece of the lead, but ballooned to a 76 while trying to keep up with the long-hitting pros.
Former PGA Tour player Keith Clearwater was the low senior pro with a 2-under 214.
But Saturday's spotlight was on Fielding, who is in professional golf limbo right now as he tries to get some playing status back. He will have to Monday-qualify for the Utah Championship in July at Willow Creek Country Club, but likes his chances now.
"I really struggled last year," he said. "I couldn't keep the ball in play, and then it just funneled down. I lost confidence and I really played horribly all year. It was the worst year I have every played, actually."
Cole Ogden just edged Devon Purser for low amateur honors as Purser made a late run with a 68 on Saturday. Ogden, who will be a senior at BYU next fall, said the golf course was more difficult than it usually is this week because the wind blew hard a lot of the time.
"I like the way I am playing right now," he said. "Shooting three solid rounds here this week wasn't easy."
