No. 4 seed Odesnik ousted in Tiburon

   Jeff Dadamo continued his Northern California success Tuesday.
   Dadamo, a 23-year-old qualifier, surprised fourth-seeded Wayne Odesnik 6-4, 6-3 in a first-round matchup of left-handed Floridians in the $100,000 First Republic Bank Tiburon Challenger at the Tiburon (Calif.) Peninsula Club. Dadamo is from Tampa, and Odesnik, 26, lives in Weston, near Fort Lauderdale.
   Dadamo won the 2011 NCAA doubles title with Texas A&M teammate Austin Krajicek at Stanford, 50 miles south of Tiburon in the San Francisco Bay Area, and reached the final of a $15,000 Futures tournament in Sacramento in June.
   Odesnik also has excelled in Northern California, winning the 2007 Sacramento Challenger.
   James Blake and Mischa Zverev, Sunday's finalists in the $100,000 RelyAid Natomas Challenger, won their first-round matches in Tiburon and could meet in the quarterfinals.
   Blake, the No. 2 seed and Sacramento champion, defeated fellow American Alex Kuznetsov, a quarterfinalist the last two years in Tiburon, 6-4, 6-4. Zverev, a Moscow-born German, beat American wild card Michael McClune 3-6, 6-2, 6-1.
   Top-seeded Benjamin Becker, a German who lost in the first round of the Sacramento Challenger, topped U.S. qualifier Steve Meister 7-6 (4), 2-6, 6-1.
