Caroline Wozniacki reached the second round of the ASB Classic in Auckland, New Zealand with a 6-4, 6-4 victory over Danka Kovinic on Tuesday, but two other former No. 1-ranked players were not able to get out of the opening round.
Top-seeded defending champion Venus Williams fell 6-7(4), 6-3, 6-3 to Russian teenager Daria Kasatkina, while British qualifier Naomi Broady took out No. 2 seed Ana Ivanovic in straight sets 7-5, 6-4. Williams was not able to hold on after winning the first set and leading 3-1 in the second against Kasatkina, who was playing her first career match against a Top 10 player.
It did not look good early on for the third-ranked Wozniacki, who fell behind 4-0 in the opening set before rallying to win the next seven consecutive games.
"It wasn't a great start for me, but a good start for her," Wozniacki said. "I just had to get my wheels going and then I won seven games in a row, and I really felt like it was getting there. It's always tough in the first match of the season. You just want to get a good start and get the matches going.
"Honestly I was just trying to find my rhythm. She went for every shot and I wasn't keeping up."
In other first round action, No. 7 seed Barbora Strycova beat Dutch qualifier Kiki Bertens 6-2, 604
Australia's Samantha Stosur could not survive her second three-set match in as many days, falling 6-1, 6-7(3), 6-4 to No. 6 seed Carla Suarez Navarro in the second round of the Brisbane International.
