Riffice, Klinger reach Easter Bowl boys 18 quarters

   Two Sacramento-area boys have reached the 18-and-under quarterfinals in the Easter Bowl.
   No. 14 seed Sam Riffice of Roseville ousted No. 3 Ulises Blanch of Deerfield Beach, Fla., 6-1, 3-6, 6-2 on Thursday at Indian Wells. Also, Cameron Klinger of Elk Grove defeated John Jorgeson of Bradenton, Fla., 6-1, 7-5.
   Riffice, who trains at the USTA center in Boca Raton, Fla., will face 10th-seeded Mwendwa Mbithi of Deerfield Beach. Klinger will meet top-seeded Taylor Fritz of Rancho Santa Fe.
   Fritz, the runner-up in the inaugural ITF Junior Masters in Chengdu, China, last week, beat 15-year-old qualifier Patrick Kypson of Greenville, N.C., 4-6, 7-5, 6-2 after trailing 6-4, 5-0.
   Meanwhile, three Northern Californians reached the boys 18 doubles semifinals with separate partners as the No. 1, No. 2 and No. 7 seeds lost, and a NorCal player is guaranteed to advance to the final. 
   Jake DeVine of Los Altos Hills and Kypson upset top-seeded Fritz and Catalin Mateas of Braintree, Mass., 6-3, 6-2 in the quarterfinals.
   Sixth-seeded Vasil Kirkov of Tampa, Fla., and Riffice eliminated second-seeded Blanch and Liam Caruana of New Braunfels, Texas, 7-6 (0), 6-2.
   And Klinger and Nathan Ponwith of Scottsdale, Ariz., topped seventh-seeded Zeke Clark of Tulsa, Okla., and Nathan Perrone of Bluffton, S.C., 6-4, 6-4.
   In the semifinals, DeVine and Kypson will battle Klinger and Ponwith, and Kirkov and Riffice will play fifth-seeded Trent Bryde of Suwanee, Ga., and Emil Reinberg of Atlanta.
