BRISBANE, Australia (AP):
Serena Williams has carried her relentless winning form into 2013, reaching the Brisbane International quarter-finals with a 6-2, 6-2 victory over Alize Cornet on New Year's Day.
After the unexpected exits of No. 2 Maria Sharapova, who pulled out with an injured right collarbone, and 2011 champion Petra Kvitova yesterday afternoon, third-ranked Williams needed only an hour to beat the No. 44-ranked Cornet - unleashing one of her fastest ever serves for good measure - in the night match.
The 15-time major winner has lost only one of her last 34 competitive singles matches in a run that includes titles at Wimbledon, the London Olympics and the US Open.
She was hitting winners so fiercely that Cornet didn't bother chasing most of them, and she fired a serve at 200 kph (124 mph) in the fourth game of the second set.
