Serena easily advances in Montreal

Montreal, QC ( - Defending champion Serena Williams had little trouble moving into the third round Wednesday at the $2.44 million Rogers Cup tennis event.

The top-seeded world No. 1 needed a mere 58 minutes to dispose of former U.S. Open champ Samantha Stosur, with Williams ripping off 10 aces en route to a 6-0, 6-2 rout.

Williams, fresh off last week's title in Stanford, is a three-time Rogers Cup champ (2001, 2011, 2013) and one-time runner-up (2000). The American star downed Stosur in the 2011 Montreal final, with the Aussie veteran turning the tables on Williams in the U.S. Open title match a month later.

Reigning Wimbledon champion and 2012 Rogers Cup titlist Petra Kvitova also cruised in her second-round bout with Casey Dellacqua, with the second-seeded Czech rolling to a 6-3, 6-2 decision over her Australian foe.

French Open champion Maria Sharapova was a come-from-behind second-round winner on Wednesday, as the fourth-seeded former world No. 1 fought back to beat rising Spaniard Garbine Muguruza 4-6, 6-3, 6-1 on the hardcourts at Uniprix Stadium.

Sharapova, who has now won 11 of her last 12 matches on tour, was a runner-up at this event in Toronto in 2009. Her third-round opponent will be capable Spaniard Carla Suarez Navarro.

Meanwhile, sixth-seeded German left-hander Angelique Kerber whipped France's Caroline Garcia 6-4, 6-1, No. 7 seed Jelena Jankovic rallied to edge American Sloane Stephens 6-7 (7-9), 6-4, 7-6 (7-4), American Coco Vandeweghe took down 2006 Rogers Cup champ Ana Ivanovic 6-7 (7-9), 7-6 (9-7), 6-4 and 11th- seeded former world No. 1 Caroline Wozniacki pasted Czech Klara Koukalova 6-1, 6-2.

Kerber has reached, and lost, in four finals this season, including last week versus Serena Williams in Stanford. Wozniacki was the Rogers Cup champ back in 2010, while Jankovic reached the finals in Montreal in 2007.

Kerber's next opponent will be Venus Williams after the seven-time Grand Slam winner handled qualifier Yulia Putintseva of Kazakhstan 6-3, 6-2.

In other second-round action involving seeds, British qualifier Heather Watson ousted No. 10 Aussie Open runner-up and 2008 Montreal finalist Dominika Cibulkova of Slovakia 6-2, 6-7 (3-7), 7-6 (7-5), a No. 14 Suarez Navarro held off Czech lucky loser Karolina Pliskova 6-1, 3-6, 6-3, and No. 15 Czech Lucie Safarova handled Slovak Magdalena Rybarikova 6-4, 6-2.

Safarova will next face Serena Williams in the third round.

Also on Day 3, 2013 Wimbledon runner-up Sabine Lisicki of Germany grounded American Madison Keys 4-6, 6-1, 6-4 and Ekaterina Makarova routed fellow Russian Elena Vesnina 6-3, 6-2.

The 2014 Rogers Cup champ will collect $467,300.
