TENNIS / NCAA CHAMPIONSHIPS : USC’s No. 1, Black, Advances, but Leach, UCLA’s Janecek Lose

Top-seeded Wayne Black of USC held off an aggressive second-set comeback by Tennessee’s Chris Mahony to win, 6-1, 7-5, in Thursday’s second round of the NCAA men’s tennis championships.

But Black’s teammate, Jon Leach, fell to Jan Hermansson of Southern Alabama, 4-6, 4-6.

Leach, the hero of USC team title-clinching match against Stanford on Tuesday, said he was outmatched by Hermansson.

“He was just too good today,” Leach said. “If he plays like he did today, he will do well in the tournament.”

Leach was joined on the sideline by third-seeded Rob Janecek of UCLA, who was upset by Vaughn Synman of Alabama Birmingham, 6-1, 2-6, 6-0.

Second-seeded Marcus Hilpert of Arkansas stayed on target for a match against Black by beating Tad Berkowitz of New Mexico, 5-7, 6-1, 6-4.

Two Pepperdine players lost.

Michael Flanagan of Stanford defeated the Waves’ Ari Nathan, 6-4, 6-1, and Mike Sell of Georgia defeated Pepperdine’s Charles Auffray, 6-1, 6-3.
