Pro golfers trying to reach the PGA Tour battled it out in Q-School at Ak-Chin Southern Dunes this week.

A windy Friday in Maricopa played havoc with several golfers trying to qualify for the PGA and knocked several contenders out of advancement to Stage 2.

Ak-Chin Southern Dunes saw the Web.com Tour Qualifying School First Stage Tournament wind up with 28 scoring well enough to move on. The top 23 scores and ties advanced to Second Stage, with a time and place yet to be determined.

Chris Satterlee of Phoenix held steadiest of the four men who were at the top of the leaderboard at the beginning of the day. His 66-70-67-70—273 was good enough for 15 under and a one-stroke victory.

Satterlee’s Q-School was paid for by the Pepsi Tour, where he is the money leader.

While others ahead of them faltered, Xander Schauffele of San Diego and Trevor Murphy of Scottsdale both made big moves Friday to tie for second.

Garrett Sapp, who led after two rounds, finished in eighth place. John Chin, who led after three rounds, finished seventh.

Ak-Chin Southern Dunes has been a go-tour course for tournaments this year. The Q-School was the fifth high-level competition in the last eight weeks.
