Sydney: World No. 8 Caroline Wozniacki pulled out of her first-round match at the Sydney International with a wrist injury on Monday, just a week before the start of the Australian Open.

The 24-year-old Dane, who lost the final of the Auckland Classic on Saturday, had already had her left wrist strapped when she was forced to retire at 6-4, 1-1 down to Czech Barbora Zahlavova Strycova.

“I didn’t want to do it worse before Melbourne, so I’m just going to try and get some treatment on it and try and get ready for next week,” Wozniacki told reporters.

“I still have a week to go, so hopefully it’ll be fine... I’m confident that I’ll be fine to play in Melbourne.”

Zahlavova Strycova went through to a second-round tie against local hope Sam Stosur, who had earlier progressed with a rain-disrupted 7-6 (3), 5-7, 6-3 victory over another Czech in Lucie Safarova.

Former US Open champion Stosur had already had her first-round contest put back a day after wet weather in Sydney on Sunday.

She held her nerve throughout a three-hour contest peppered with rain interruptions and polished off the victory over the world number 16 with a thumping ace down the middle.

It was a welcome return to winning ways for Stosur, who blew a 5-1 lead in the third set last week to lose to American Varvara Lepchenko in Brisbane.

Third seeded Pole Agnieszka Radwanska enjoyed the more clement later conditions to beat France’s Alize Cornet 6-3, 6-2 and reach the second round of a tournament she won in 2013.

The world No. 5 made it clear, however, that her focus over the next few weeks under new coach Martina Navratilova was on improving on a single semi-final appearance at Melbourne Park.

“Martina’s going to be here tomorrow,” Radwanska said. “She’s really helping me on and off court. The goal is the grand slams so we’ll see how it goes.” (reuters)
