But Auproux had to fight to make it to the final four. In the round of 16, he bested Chase Masciorini of Dana Hills, 6-1, 3-6, 6-4, before defeating Tomas Aranguiz of Ayala, 6-3, 4-6, 6-0.
"I'm happy to make it to the semifinals, but my goal is to win the whole thing," Auproux said. "It's great that I made it this far, but I'm hoping to keep going.
"I played pretty well today, but I could have played better. Both of by opponents also played pretty well."
Auproux will take on defending champion Gage Brymer of Irvine University at 11 a.m. Saturday in the semifinals. Brymer won the singles title at the Ojai Tournament the past two years.
"I played him at Ojai the first year that he won it and I lost just 6-4 in the third," Auproux said. "I just want to play my hardest and hopefully I can win."
Brymer advanced to the semifinals with a 7-5, 7-6(7-4) win against Victor Brown of Alta Loma. He also got by Cate's Blake MacKall in the round of 16, 6-4, 6-1.
"He had his moments today, but he was able to get the two wins," Burroughs Coach Roy Bernhardt said.
"In last year's tournament, he played hard and had a lot of fun. But he's just playing so much better this year."
Auproux, a two-time Pacific League singles champion, is fresh from helping his Burroughs team advance to the CIF Southern Section Division II semifinals for the second consecutive season. The Indians lost to No. 1-seeded Palm Desert, 14-4, on Tuesday.
