Six-time winner Serena Williams survived a first-set scare before overcoming Yaroslava Shvedova 7-6 (9/7), 6-2 Thursday to power into the third round of the ATP and WTA Miami Masters.
The top-seeded defending champion will next face France’s Caroline Garcia after dispatching her Kazak rival in one hour, 45 minutes.
Fourth seed Maria Sharapova, the 2013 runner-up to Williams, outlasted Japan’s Kurumi Nara 6-3, 6-4 in another opening test.
Williams lost a 3-1 lead and trailed 3-5 as Shvedova shifted her game up a gear.
Williams got back on track in the nick of time with a break for 5-all. A love game then ended with an ace for Williams before the set went to a tie-breaker.
In the decider, the 32-year-old Williams saved three set points as a nervous Shvedova missed her big upset chance in front of a screaming house full of her rival’s supporters.
After she also missed on a third, the Kazak handed over a set point to Williams, who finally finished off the 63-minute set on her second opportunity.
Hewitt wins 600thAustralian veteran Lleyton Hewitt captured his 600th career victory while countryman Bernard Tomic became the fastest loser in ATP history.
Former number one Hewitt rallied to defeat Dutchman Robin Haase 2-6, 6-3, 6-3 to reach the second round while Tomic fell in his first match since January hip surgery 6-0, 6-1 to Finland’s Jarkko Nieminen.
Tomic, ranked 74th, crashed out in 28 minutes, 20 seconds, believed to be the ATP’s shortest match by a minute. Tomic was playing for the first time since a retirement against Rafael Nadal in a first-round match at the Australian Open.
Hewitt, 33, turned in another of the trademark fightbacks which have characterized a career that included Grand Slam crowns at Wimbledon in 2002 and the US Open in 2001.
The 44th-ranked Australian reversed course in the second set to reach the second round in just under two hours, with Haase saving a match point before exiting.
"It’s not something you focus on, to tell you the truth. I totally forgot," Hewitt said of his 600th triumph.
