Quan coasts, but four others fall in Junior Orange Bowl

   Rudy Quan rolled into the round of 16 in the boys 12s today at the Junior Orange Bowl.
   But the other four remaining Northern Californians lost in the third round of their respective age groups in Coral Gables, Fla.
   The top-seeded Quan, from the Sacramento suburb of Roseville, demolished unseeded Matthew Yang of Canada 6-0, 6-0. Quan -- who has won gold balls this year in the Winter Nationals, Easter Bowl, Clay Courts and Hard Courts -- has lost only four games in his three matches.
   Quan will play Danial Rakhmatullayev, a qualifier from Kazakhstan who surprised ninth-seeded Maxwell Exsted of Savage, Minn., 6-3, 7-6 (1).
   Meanwhile, No. 9 seed Jaden Weekes of Canada beat No. 17 seed Herrick Thomas Legaspi of Sacramento 6-3, 6-4 in the boys 14s.
   No. 5 seed Vivian Ovrootsky of San Jose and unseeded Ria Bhakta of Saratoga in the San Francisco Bay Area lost in the girls 14s. No. 17 seed Gracie Epps of Norman, Okla., topped Ovrootsky 4-6, 7-5, 6-1, and No. 2 seed Eleana Yu of Mason, Ohio, eliminated Bhakta 6-1, 6-4.
   In a matchup of unseeded players in the girls 12s, Shanice Roignot of France outplayed Esther Vyrlan of Sacramento 6-3, 6-3.
