Sanchez, 17-year-old Hardebeck gain quarters

   Maria Sanchez, a wild card from Modesto, and Krista Hardebeck, a 17-year-old qualifier headed to Stanford in the fall, reached the quarterfinals of the upset-filled $50,000 Audi Melbourne Pro Tennis Classic in Indian Harbour Beach, Fla.
   Sanchez ousted seventh-seeded CoCo Vandeweghe, a member of the Sacramento Capitals in World TeamTennis, 6-3, 6-2 Thursday to improve to 20-7 in singles this year.
   Last year's Pacific-10 Conference Women's Player of the Year as a senior at USC, Sanchez has more than halved her world ranking from No. 687 to No. 341 in 2012. Vandeweghe, 20, is ranked No. 154.
   Hardebeck, an Australian Open junior girls semifinalist in January, outplayed qualifier Alyona Sotnikova of Ukraine 7-5, 6-2.
   Six seeds lost in the first round, and the other two fell in the second round. Next for Sanchez is Canada's Heidi El Tabakh, ranked No. 210. Hardebeck, from Santa Ana in the Los Angeles area, will take on 19-year-old American Chi Chi Scholl, ranked No. 184.
   In the doubles quarterfinals, Akiko Omae of Japan and Roxane Vaisemberg of Brazil knocked off top-seeded Sanchez and Yasmin Schnack 6-1, 0-6, 10-7 tiebreak, and fourth-seeded Maria-Fernanda Alves of Brazil and Jessica Moore of Australia defeated Irina Falconi of Atlanta and Vandeweghe by walkover.
   Schnack, who turns 24 today, will return for her second season with her hometown Capitals in July.
   WTA, ATP World Tour in Estoril, Portugal -- Raquel Kops-Jones, a former NCAA doubles champion from Cal, and Abigail Spears of San Diego lost to Alexandra Panova of Russia and Heather Watson of Great Britain 6-4, 6-1 in the quarterfinals.
   In the first round of men's doubles, John Paul Fruttero, a former Cal All-American, and Raven Klaasen of South Africa fell to Johan Brunstrom of Sweden and Philipp Marx of Germany 7-6 (6), 6-3.
   Fruttero and Klaasen won a Challenger doubles title in Taiwan last week.
