Muguruza and Kerber bounce Czechs at WTA Finals

SINGAPORE — Heavy-hitting baseliners Garbine Muguruza and Angelique Kerber brushed aside Czech challengers to make a winning start to their WTA Finals campaign Monday. Spaniard Muguruza dispatched Lucie Safarova 6-3, 7-6 (4) before Germany's Kerber overcame an error-strewn and unwell Petra Kvitova 6-2, 7-6 (3) in a battle of the lefties in another White Group encounter. The 22-year-old Muguruza served confidently, raining down 10 aces, and controlled the baseline exchanges with aggressive strokes on the slower indoor hardcourt at the Singapore National Stadium. The world No. 3 from Spain has been in strong form since she lost to Safarova in the quarterfinals of the French Open. "I think I'm making better choices ... wait for the perfect ball to really attack," Muguruza told reporters. "You have to be aggressive, but in a good way, making good choices." Wimbledon runner-up Muguruza broke French Open finalist Safarova in the third game of the first set and pressurized her serve throughout a one-sided opening salvo. Safarova broke at the start of the second set but the Spaniard, who won the biggest title of her career at the China Open earlier this month, broke back in the sixth game as she regained her rhythm. The Venezuelan-born Muguruza broke the world No. 9 to love in the sixth game thanks to her heavy groundstrokes and dominated the tiebreak from the start. It was a revenge win after she and compatriot Carla Suarez Navarro lost to Safarova and Bethanie Mattek-Sands in their doubles opener Sunday. The day's second singles lacked the same quality with twice Wimbledon champion Kvitova all at sea, offering up 44 unforced errors. A lethargic Kvitova, diagnosed with mononucleosis in August, rallied at the start of the second set to go 3-0 up, only to lose the momentum as world No. 7 Kerber raced 5-4 ahead with a booming forehand down the line. The German showed nerves as she faltered and lost her serve when attempting to close out the match but Kvitova wasted set points at 6-5 as Kerber forced a tiebreak. A wild service return then handed Kerber a winning start to the eight-player championships. "I feel weird," said world No. 5 Kvitova of her ailment. "It's really tough to describe. "I couldn't really do what I wanted. I felt I wasn't able to stay in the kind of good rallying that she played." Pospisil beats Giraldo In Valencia, Vasek Pospisil advanced to the second round of the Valenica Open following a 6-4, 6-3 win over Santiago Giraldo Monday. Pospisil, the fifteenth-seeded Canadian, had won all three of his previous matches against the Colombian. Extending that record proved straightforward, as Pospisil used his big serve and powerful forehand to good effect, wrapping up the victory in 1 hour and 10 minutes. The 25-year-old Pospisil held his serve to love in his opening three service games before breaking Giraldo in the tenth game for the opening set. Although the South American offered a stern resistance in the second, saving four break points in a marathon 10 minute sixth game, Pospisil eventually served out the match. — Agencies
