Geoff Gonzalez, Elliott Paylor, Joey Garber and Hunter Stewart all earned spots in the 2016 Barracuda Championship through the Monday qualifier.
Gonzalez, Paylor and Garber each shot 6-under 66 to share medalist honors at Hidden Valley Country Club in Reno, Nev.
Stewart played his way in the event by shooting 67 in the 18-hole event, then surviving in a three-for-one playoff for the last spot.
Gonzalez, who went to Cal Poly, is the 2009 California Amateur winner, and he's making his PGA Tour debut this week. He made five starts on the Mackenzie Tour in 2014, making just one cut.
Paylor is also making his PGA Tour debut this week. He's an assistant pro at Eagle Vines Vinyards & Golf Club in Vacaville, Calif.
The 24-year-old Garber finished 108th on the Mackenzie Tour money list last season. He was a second-team All-American at the University of Georgia in 2014. This will be his second PGA Tour start, having missed the cut at the 2014 Travelers Championship.
Stewart, a member of the 2015 U.S. Walker Cup team, will be making his 10th PGA Tour start. The Vanderbilt product has made two of nine prior cuts, including a 10th place finish at the OHL Classic at Mayakoba in November.
