BAD GASTEIN, Austria (AP) -- Sara Errani made a successful transition from grass to clay with a straight-sets win over Katerina Siniakova of the Czech Republic at the Gastein Ladies on Tuesday, three days after winning the doubles title at Wimbledon with fellow Italian Roberta Vinci.
The 14th-ranked Errani, who was seeded second, saved five of six break points against her serve to defeat Siniakova 6-3, 6-2. Errani, who next plays Paula Ormaechea of Argentina, is the highest ranked player left in the event after top-seeded Flavia Pennetta pulled out injured on Monday.
The sixth-seeded Austrian won four straight games from 5-3 down in the final set to close out the victory. The 99th-ranked Smitkova led 30-0 while serving for the match at 5-4 but failed to score another point in the game.
Also, No. 3 Carla Suarez Navarro of Spain defeated Laura Siegemund of Germany 7-6 (3), 1-6, 6-4; No. 4 and 2009 champion Andrea Petkovic of Germany beat Jana Cepelova of the Czech Republic 7-6 (8), 7-5; No. 5 Elina Svitolina of Ukraine downed Patricia Mayr-Achleitner of Austria 6-1, 6-4; and No. 7 Camila Giorgi of Italy defeated last year's finalist, Andrea Hlavackova of the Czech Republic, 6-2, 6-3.
