Auproux, the two-time defending Pacific League champion, earned a bye in the first round of the competition. He then faced Charlie Werman of Viewpoint in a second-round contest. Auproux was able to breeze to a 6-1, 6-0 win.
"I thought I played pretty well in that first match," Auproux said. "Usually the first match is the hardest, but I was able to do pretty well against him."
The win put Auproux into the third round against Sean Holster of Arroyo Grande. Although the Burroughs standout had to work to win the first set, he came back and took the match, 6-3, 6-1.
"I was able to serve really well today," Auproux said. "No one broke my serve at all. I just wanted to go out and play a solid game and hopefully move on."
For the second season in row, Auproux advances to the round of 32. The tournament will be held Thursday at the Whittier Narrows Tennis Center. By doing well in that event, Auproux will move on to the round of 16 and quarterfinals Friday at the Seal Beach Tennis Center.
In 2011, Auproux advanced to the round of 16 but lost. He said he thinks he has a good chance to advance to the quarterfinals this year.
"I'm older, I know what to expect and I'm more mature with my game this year," he said. "Last year I was a sophomore and nobody really wins it as a sophomore."
Also in singles, Fox — the league runner-up — was successful in his first-round match, beating Jeffrey Burr, a freelance player, 6-0, 6-1. However, Fox fell in the second round to Cristobal Rivera of Santa Monica, 6-0, 6-0.
Like Auproux, Lam and Hoang — the league doubles champs — got a bye in the first round. The Indians duo won its second-round contest against a pair from Camarillo, 6-0, 6-3, before faltering in the third round against a team from Santa Barbara, 3-6, 4-6.
"The guys really played well today," Burroughs Coach Roy Bernhardt said. "In that first round all of our guys were able to win pretty easily. But the competition in the other rounds was very tough."
Burroughs still has more tennis to play as a team. The Indians will take part in the CIF Southern Section Division II semifinals at 3 p.m. Tuesday at No. 1 Palm Desert.
