NorCal juniors Bellis, Riffice advance in Eddie Herr

   The number of Northern California juniors remaining in singles at the Eddie Herr International Junior Championships in Bradenton, Fla., was whittled in half today.
   In the girls 18s, top-seeded CiCi Bellis of Atherton reached the round of 16, but unseeded Michaela Gordon of Saratoga surprisingly lost. Both San Francisco Bay Area residents are 15.
   Bellis, who stunned Australian Open runner-up Dominika Cibulkova in the first round of women's singles at the U.S. Open in August, beat unseeded Destanee Aiava of Australia 7-6 (7), 6-0.
   Gordon fell to unseeded Maia Lumsden of Great Britain 1-6, 6-4, 6-3 after drubbing her 6-2, 6-1 in the girls round of 16 at Wimbledon in July.
   Playing on the boys' side today were Sam Riffice and Keenan Mayo, who grew up a few houses apart in the Sacramento suburb of Roseville before moving to the USTA training centers in Boca Raton, Fla., and Carson, Calif., respectively.
   Riffice, the top seed in the boys 16s, outlasted 10th-seeded Trent Bryde of Suwanee, Ga., 1-6, 6-3, 6-3 to reach the quarterfinals. But Mayo, seeded ninth in the boys 14s, lost to his doubles partner, eighth-seeded Roscoe Bellamy of Pacific Palisades in the Los Angeles area, 6-2, 6-1 in the round of 16.
   Both Riffice and Mayo advanced to the doubles quarterfinals with straight-set victories. Riffice is seeded first with Vasil Kirkov of Tampa, Fla., and Bellamy and Mayo are seeded second.
