Key Biscayne, FL (SportsNetwork.com) - Six-time champion Serena Williams was tested in a third-round victory at the $5.4 million Sony Open.
The reigning U.S. and French Open titlist and world No. 1 great snuck past promising Frenchwoman Caroline Garcia, 6-4, 4-6, 6-4, on the hardcourts of Crandon Park, where rain interrupted play on Saturday.
The 32-year-old Williams, who is now 11-2 overall in 2014, improved to 3-0 lifetime against the 20-year-old Garcia.
Williams, who is also a two-time runner-up at this lucrative event, defeated five-time Miami runner-up Maria Sharapova in last year's marquee finale in south Florida.
Meanwhile, fifth-seeded German Angelique Kerber moved on by pasting capable Bulgarian Tsvetana Pironkova 6-0, 6-2; eighth-seeded former Wimbledon champ Petra Kvitova handled Croatian qualifier Donna Vekic 6-3, 6-4; 23rd-seeded Russian Ekaterina Makarova upended ninth-seeded Italian Sara Errani 6-3, 2-6, 6-4; and 12th-seeded former world No. 1 Ana Ivanovic of Serbia cooled off last week's surprise Indian Wells champion, 20th-seeded Italian veteran Flavia Pennetta, 6-4, 6-3.
Fourteenth-seeded German Sabine Lisicki pulled out of the draw on Saturday, thus giving 19th-seeded Belgian Kirsten Flipkens a walkover into the fourth round. Lisicki was last year's Wimbledon runner-up.
The 2014 Miami champ will collect $787,000.
