Williams, who has won seven Miami titles, is competing a week after pulling
out of her semifinal at Indian Wells because of a knee injury.

The winner of her match will face promising 15-year-old American CiCi Bellis,
who upset 29th-seeded Zarina Diyas 6-2, 6-1 on Friday.

Third-seeded Simona Halep, fresh off her big title at Indian Wells, moved on
with a 6-4, 2-6, 6-1 win over Nicole Vaidisova on Crandon Park hardcourts.

setback coming in the quarterfinals of the Australian Open in January. She’s
seeking her third title in her last three events.

In a battle of former world No. 1s, two-time Miami champion Victoria Azarenka
cruised to a 6-1, 6-1 win over 20th-seeded Jelena Jankovic, who was fresh off
a runner-up finish to Halep last week in the California desert.

A top-10 upset came when Johanna Larsson beat No. 10 seed Lucie Safarova 7-6
(7-5), 6-2, while 15th-seeded Flavia Pennetta moved on by overcoming Tsvetana
