Luo added, "And after that, I made a couple of birdies and was able to close it out. So I am glad I did not know where I stood."

Virginia Tech commit Leonardo Vieira of San Leandro, Calif., and San Jose State freshman Avinash Iyer of San Ramon, Calif., finished T2 with a score of 4-under. University of Washington junior Justin Hopkins of Danville, Calif., and Saint Mary's College Senior Zach Missigman of Goodyear, Ariz., finished T4 at 3-under.

In the first round, Luo had six birdies, one bogey, and a double bogey to start the tournament with a 3-under 69. 

Luo, whose teammates call him XL, was standing in the fairway on No. 18 with a tough approach shot and the championship there for the taking from 142 yards.

Cooper Mapes

"It was a little downwind, so I tried to jump on a pitching wedge," Luo said. "I hit a low draw into the green, and it hit pin high, and it jumped 15 or 17 feet past the hole. I was really happy with that shot."

Luo made his par comfortably and secured his championship win. 

AJ Fitzgerald of Salinas, Calif., finished at 2-under and in solo sixth place to round out the under-par finishers. 

Cooper Mapes of Pleasanton, Calif., recorded his first ever hole-in-one, acing the par-3 No. 5 with a pitching wedge from 133 yards out. Mapes finished T43 at 7-over for the tournament, but that hole is one he will never forget.

Craig Miyamoto

As Pete Wlodkowski of AmateurGolf.com was packing up and getting ready to head to the San Diego event at Aviara Golf Club, he spotted Xuan Luo heading to his car. Luo kept it short and sweet when he asked how he felt.

I'm over the moon right now." Luo said.
