Friday, Third Round
 Flavia Pennetta (ITA #28) vs. Victoria Azarenka (BLR #36)
Head-to-head: Azarenka leads 2-1
Pennetta may have failed to defend the trophy in Indian Wells, but she displayed more than enough to suggest that her Indian summer on tour will not be drawing to a close any time soon.
Despite her opponent's form, Azarenka, as ever, will not be lacking in self-belief. The former World No.1 is clearly relishing being back on tour and competing regularly after an injury-ravaged couple of years. In the previous round, she was particularly impressive, dropping just two games against Jelena Jankovic to revive memories of her title runs in Crandon Park of 2009 and 2011.
 Serena Williams (USA #1) vs. [WC] CiCi Bellis (USA #211)
Head-to-head: first meeting
On April 8, 1999, Catherine Cartan Bellis was born in San Francisco. Around five months later, on the other side of the country, a teenage Serena Williams picked up her maiden Grand Slam title. In the following years, Williams has fended off wave upon wave of young pretenders to reign supreme at the top of the women's game. To emphasize just how long she has been waging this battle, Bellis, whom she meets in the afternoon session on Stadium, will be the 17th different year-end junior No.1 she has taken on.
Despite the magnitude of the task ahead of her, Bellis showed when she upset Dominika Cibulkova at last year's US Open that she cares little for reputation. However, Williams is a different proposition to Cibulkova, particularly in Miami, where she is bidding to be crowned champion for an eighth time.
Stat to watch: Williams' combined win-loss record against those 17 previous junior No.1s is 64-13.
