David Ferrer is already into his second semifinal of the young 2013 season while Bernard Tomic stays hot in Sydney.

American women continue their surge during week two of the tennis season, while Bernard Tomic wins and Grigor Dimitrov falls.

Two players on the sidelines are trying to figure out how to tweak their games in time for the Australian Open — both dealing with equipment issues. Maria Sharapova switched from her long-time Prince racquet to a multi-million sponsorship with HEAD, but last week lost early in her only WTA warm-up event. This week world No. 1 Caroline Wozniacki debuted her cash-grab switch to Yonex, losing her opening-round match. Wozniacki vaulted to No. 1 behind her long-time association with her Babolat racquet. Before the event, Wozniacki and her Yonex won one game off Vera Zvonareva in an exhibition match.

The list of floaters almost as impressive as the seed list; tough openers include Kirilenko vs. Cibulkova (winner to face (1) Wozniacki), (5) Schiavone vs. Kleybanova (winner to likely face Hantuchova), possible (3) Clijsters vs. Petrova 2nd rd., former world No. 2 Kuznetova vs. (WC) Dokic, winner to face (4) Stosur vs. Wickmayer winner, (6) Jankovic vs. Rezai, and (2) Zvonareva vs. winner of Pennetta vs. qualifier; 7 of the Top 10 players present in Sydney; Elena Dementieva (now retired) beat Serena Williams (now injured) in the 2010 final…Clijsters (2007, ’03) is the lone returning champ in the field, in addition to the 2008-05 runner-ups Kuznetsova (2008), Jankovic (2007), Schiavone (2006), and Stosur (2005); 11 former No. 1 players have won the Sydney title.
