Last remaining seed falls in Aptos Challenger

   The last remaining seed lost Thursday in the second round of the $100,000 Comerica Bank Challenger in Aptos, Calif.
   No. 6 Florent Serra of France fell to Serbian qualifier Ilija Bozoljac, last year's runner-up, 6-3, 6-4 at the Seascape Sports Club.
   Also losing were wild card Robby Ginepri, a U.S. Open semifinalist in 2005, and Maxime Authom, who upended top seed Brian Baker on Tuesday in the first round.
   Lucky loser Michael McClune took out Ginepri 6-1, 7-6 (4) in an all-American matchup, and Jimmy Wang of Chinese Taipei outclassed Authom 6-4, 4-6, 6-1. Wang trains part-time at the Gorin Tennis Academy in the Sacramento suburb of Granite Bay, Calif.
   In today's quarterfinals, beginning at 11 a.m., Wang will face 33-year-old Czech Jan Hernych, wild card Bradley Klahn of Poway (near San Diego) will meet Robert Farah of Colombia, wild card Steve Johnson of Orange will play 32-year-old Rik de Voest of South Africa, and McClune will take on Bozoljac.
   Klahn, the 2010 NCAA singles champion, and Farah are former Pacific-10 Conference rivals from Stanford and USC, respectively.
   Johnson, Farah's ex-teammate, ended his collegiate career in May by helping the Trojans win their fourth consecutive NCAA title and capturing his second straight NCAA singles crown.
