It may not yet reach the extent of the adversity Caroline Wozniacki went through in 2014, but it is a bit of a downer start to 2015 for the Danish tennis player.

The Sydney Morning Herald reported that Wozniacki pulled out of her opening match at the Sydney International with a wrist injury on Monday, just one week before the start of the Australian Open.

According to the Herald, Wozniacki entered her match against Barbora Zahlavova Strycova with her wrist already taped. Wozniacki, the No. 4 seed, lost the first set 6-4 but saved break points on her serve to start the second set, lost the next game on Zahlavova Strycova's serve and called it quits.

The Herald reported that the 24-year-old Wozniacki jumped out to a 3-1 lead but showed herself to be in discomfort and called for the trainer on multiple occasions to tend to the wrist and provide a strap around the wrist.

The Dane said she knew when it happened.

"I felt it during one shot. I hit it against the wind and hit it late and I felt it in my wrist," she said, according to the live.sportlive.co.za website. "I've had it before so I kind of know what it is."

Wozniacki said she was hopeful the wrist would be better with a week's rest in time for the start of next week's first Grand Slam event of 2015.

"There's still a week to go and hopefully it will be fine," Wozniacki said. "We'll see how it feels on [Tuesday], but I'm confident I'll be fine to play in Melbourne. I didn't want to do it worse before Melbourne as well so I will try to get some treatment on it and try to get ready for next week."

She said she suffered the injury during the opening match and not during her run to the Auckland finals last week where she lost to Venus Williams in the final in three sets.

"It was a new thing," she said. "(The trainer) taped it up and it didn't really make a difference taped or not taped and I just felt like it was getting a bit worse.

"I felt like I wasn't going to win the match without being able to hit a proper backhand. It was only going to get worse and that's too negative. I thought it would be good to get treatment on it."

Wozniacki's 2014 started off rough on the tennis court as she dropped to a No. 15 ranking. She made comments sounding as if she might retire after marrying then-fiancé Rory McIlroy, until he announced that they had broken up in May.

Wozniacki spent the rest of the year building her professional career and personal life back up.
