Karlovic, Querrey to meet in Tiburon final

   One week ago, Sam Querrey and Ivo Karlovic met in the semifinals of the $100,000 Sacramento Challenger.
   On Sunday, they'll play for the title in the $100,000 First Republic Bank Tiburon Challenger at the Tiburon Peninsula Club.
   The third-seeded Querrey, a 6-foot-6 native of nearby San Francisco, knocked out top-seeded Ryan Sweeting of Fort Lauderdale, Fla., 6-4, 6-3 in Saturday's first semifinal. The second-seeded Karlovic, a 6-10 Croat, downed eighth-seeded Bjorn Phau, 5-9 of Germany, 7-5, 7-5.
   Karlovic outlasted Querrey 7-6 (6), 3-6, 6-4 in Sacramento in their first meeting in three years and went on to win the title. Querrey, though, leads the head-to-head series 3-2.
   The 32-year-old Karlovic is the hardest server in tennis, and Querrey, 24, isn't far behind.
   Karlovic pounded a 156-mph serve in March to break Andy Roddick's record of 155. Karlovic also set a Davis Cup record with 78 aces two years ago in a five-set loss to Radek Stepanek of the Czech Republic that lasted 5 hours, 59 minutes.
   Querrey, meanwhile, fired 10 consecutive aces in a quarterfinal victory over James Blake in Indianapolis four years ago.
   WTA tour in Osaka, Japan -- Top-seeded Vania King of the Sacramento Capitals and Yaroslava Shvedova of Kazakhstan lost to fourth-seeded Kimiko Date-Krumm, 41, and Zhang Shuai of China 7-5, 3-6, 11-9 tiebreak in the final of the $220,000 HP Japan Women's Open.
   Earlier, King and Shvedova completed a rain-suspended 6-0, 6-2 victory over third-seeded Raquel Kops-Jones, a former Cal star from Fresno, and Abigail Spears of San Diego.
   Even at 41, Date-Krumm isn't close to the record for oldest player to win a title on the WTA tour. Martina Navratilova was two months shy of her 50th birthday when she won in Montreal with Nadia Petrova in 2006.
