No. 4 seed Sam Riffice, who grew up in the Sacramento suburb of Roseville, defeated his doubles partner, No. 7 Brian Cernoch of Rockville, Md., 6-1, 7-6 (3) today in the boys 18 quarterfinals of the Easter Bowl in Indian Wells, Calif.
Riffice will face No. 10 Sebastian Korda, a resident of Bradenton, Fla., who beat Jake Sands of Pacific Palisades in the Los Angeles area 4-6, 6-1, 6-0 in the prestigious hardcourt tournament.
Korda's father, Petr, won the 1998 Australian Open to reach No. 2 in the world. Rail thin, he tested positive for doping at Wimbledon that year and was suspended for 12 months but retired shortly before the ban at age 30.
Korda's mother, Regina Rajchrtova, climbed to a career-high No. 26 in 1991. His 24-year-old sister, Jessica, won the first of her four LPGA titles in the 2012 Australian Open.
Riffice, 18, is 2-0 against Korda, 16, in ITF tournaments, both on hardcourts. In their last meeting, Riffice prevailed 7-6 (3), 7-6 (2) in the quarterfinals of the Coffee Bowl in January in San Juan, Costa Rica.
No. 2 seeds Cernoch and Riffice reached the doubles final with a 6-3, 6-3 victory over unseeded Austen Huang and Ryan Seggerman of Coronado in the San Diego region.
Cernoch and Riffice will meet No. 3 Oliver Crawford of Spartanburg, S.C., and Patrick Kypson of Raleigh, N.C.
In the boys 16 singles semifinals, No. 13 Stefan Dostanic of Irvine, Calif., overwhelmed No. 8 Ryder Jackson of Nicasio, north of San Francisco, 6-1, 6-1.
