Canada's Justin Shin shot an 8-under 64 on Thursday on PGA West's Nicklaus Tournament Course to take the first-round lead in the Web.com Tour qualifying tournament.
The 22-year-old former New Mexico State player holed two late chips, making a birdie on No. 6 and an eagle on No. 7.
"I never thought I would shoot 64," Shin said. "My plan was to try and shoot 2 or 3 under today. I missed a lot of greens but my chipping and putting helped me out in some tough situations.
Carlos Sainz Jr., Jonathan Fricke, Chris Epperson and Jason Millard shot 65. Sainz, Fricke and Millard opened on the Nicklaus course, and Epperson played the TPC Stadium Course.
The players are competing for positions in the Web.com Tour's priority ranking used to form tournament fields, with the medalist (or co-medalists) guaranteed fully exempt status. Every player who is at PGA West is guaranteed a spot on the Web.com Tour next season. The six-round tournament will end Tuesday.
