TIBURON, Calif. ? California's Florian Lakat and Andre Goransson opened their doubles campaign at the Tiburon Peninsula Club with a victory on Thursday, but the Golden Bear juniors then lost in the quarterfinals to end their run at the $100,000 Wells Fargo Tiburon Challenger.

Rain postponed the Bears' opening round of 16 match on Wednesday, but they should no ill effects one day later against professional players Denis Kudla from the United States and Dustin Brown from Germany. Goransson, a native of Hollviken, Sweden, and Lakat, from Paris, France, won, 6-3, 6-7(2), 11-9.

“Andre and Florian played a highly entertaining match today, and they matched their opponents stroke for stroke throughout the match,” Cal head coach Peter Wright said of the round of 16 match. “They fell behind in the tiebreaker but hit some timely returns and made several difficult volleys to come out on top.”

The Bears played their quarterfinal match later Thursday afternoon, as they faced another pair of pros in the third-seeded team of American Dennis Novikov and Chilean Julio Peralta. The Bears lost, 6-2, 6-2.

Cal sent a large contingent to Tiburon this year, including junior Filip Bergevi, who competed in qualifying singles. Bergevi ? ranked 64th in the ITA singles poll ? won his first match in an upset of Baylor's 31st-ranked Max Tchoutakian, 7-6(5), 6-3, but lost his round of 16 match to pro, UCLA alum and 2014 NCAA champion Marcos Giron, 7-6(3), 6-1.

“Filip's win in qualifying against a higher-ranked opponent shows how much he's improved in the last year,” Wright said. “Both his serve and forehand are more powerful, and he's being more aggressive with his returns.”

Wright added, "Having three of our current players and two of our alums (Ben McLachlan and J.P. Fruttero) playing in the Tiburon Challenger shows how hard our guys work and how successful they are at taking advantage of the opportunities to play side-by-side with some of the top players in the world."
