KEY BISCAYNE, Fla. (AP) Precocious amateur CiCi Bellis says she's ready to take on the best of the pros - Serena Williams.
Bellis, a 15-year-old American who made a big splash at last year's U.S. Open, advanced Friday to a potential third-round match against Williams by beating Zarina Diyas 6-2, 6-1.
Williams' second-round match Friday night against Monica Niculescu was postponed until Saturday because of rain. But Bellis was already relishing the chance to take on the 19-time Grand Slam champion.
