Stanford's Bradley Klahn downed USC's Steve Johnson, 6-4, 6-2, in the championship match of the Sherwood Collegiate Cup in Westlake Village on Monday.
The second-seeded Klahn beat Trojan Daniel Nguyen, 6-3, 6-4, in Sunday's semifinal while the top-seeded Johnson defeated USC teammate Ray Sarmiento to reach the title match.
Klahn returned to the court with partner Ryan Thacher and earned the doubles championship with an 8-6 win over Baylor's top-seeded Roberto Maytin and John Peers.
Klahn and Thacher are ranked 16th in the country while the Bears' duo is ranked fourth.
"It is clear to me that John and Roberto are as good as any team in the country," Baylor assistant coach Chris Brandi said. "The exciting thing is they have a ton of room to improve and we expect really big things out of them this year."
Maytin and Peers opened a 3-0 advantage in the doubles match. Klahn and Thacher, the second-seeded pair at the event, battled back to return the match on serve with Baylor leading 3-2.
The teams traded breaks in the next two games and then each tandem held serve in the next two games to give Baylor a 5-4 edge.
Stanford won the next two games to take its first lead at 6-5. The Baylor twosome responded by tying the match at six games.
Klahn and Thacher closed out the match with a break and then holding serve.
"For a match with this caliber of guys with their skill sets, you wouldn't expect that many breaks," Brandi said. "All four players have big serves, so you would think it would go a little more to form, but it didn't."
It was the fifth career singles championship for Klahn, who also won the ITA Northwest Regional Championship and NCAA Singles Championship last year after snagging the Pac-10 Championships singles crown in 2009.
Klahn and Thacher have now won five doubles championships together, including the ITA National Indoors title back in November.
Stanford opens its dual meet season a week from Tuesday when Sacramento State visits for a 1:30 p.m. start.
The Cardinal, which reached the quarterfinals in last year's NCAA tournament, opens the season with six consecutive home matches.
