Two seeds fall in Tiburon Challenger

   After one day, the $100,000 First Republic Bank Tiburon Challenger looks a lot like last week's $100,000 Sacramento Pro Circuit Challenger.
   Both seeds in action at the Tiburon Peninsula Club lost on Monday. And both are in top-seeded Sam Querrey's half of the draw.
   Not that the 6-foot-6 (1.98-meter) U.S. Davis Cup veteran, ranked 48th in the world after reaching a career-high No. 17 in 2011, needs any help.
   Jordan Thompson, 20, of Australia ousted fifth-seeded Denis Kudla of Boca Raton, Fla., 6-7, 6-3, 6-4. Kudla advanced to last year's semifinals as the top seed before losing to third-seeded Matthew Ebden of Australia.
   Also Monday, Louk Sorensen of Ireland outlasted eighth-seeded Luca Vanni of Italy 6-3, 5-7, 7-5.
   The other seed in the top half of the draw -- No. 4 Peter Polansky, the defending champion from Canada -- will open against Wayne Odesnik of Fort Lauderdale, Fla., today. Ten other matches will complete the first round.
   After the opening round in Sacramento, Querrey was the only remaining seed in the top half. He went on to win his second Challenger title in two weeks.
   The Tiburon crown would give Querrey, who has a 12-match winning streak, a sweep of the three-week Northern California swing that began in Napa. 
   Querrey reached the Tiburon singles and doubles finals in 2011. He lost to
to 6-foot-11 (2.11-meter) Ivo Karlovic in singles and with countryman Steve Johnson to Australians Carsten Ball and Chris Guccione in doubles.
