Caroline Wozniacki Announces Retirement, Wants to Start Family

That's a wrap for Caroline Wozniacki ... almost!

The 29-year-old tennis star says she's officially retiring from the sport -- right after the Australian Open in January -- to focus on other aspects of her life, including growing her family.

"I've played professionally since I was 15 years old," Wozniacki says.

"I've always told myself, when the time comes, that there are things away from tennis that I want to do more, then it's time to be done. In recent months, I've realized that there is a lot more in life that I'd like to accomplish off the court."

Caroline says getting married to NBA star David Lee "was one of those goals" -- along with "starting a family with him while continuing to travel the world."

She also wants to focus energy on raising awareness for rheumatoid arthritis -- a condition she suffers from.

"So with that, today I am announcing that I will be retiring from professional tennis after the Australian Open in January," Wozniacki says.

"This has nothing to do with my health and this isn't a goodbye, I look forward to sharing my exciting journey ahead with all of you."

As far as her tennis accomplishments, Caroline was pretty damn good.

"With 30 WTA singles titles, a world #1 ranking for 71 weeks, a WTA Finals victory, 3 Olympics, including carrying the flag for my native Denmark, and winning the 2018 Australian Open Grand slam championship, I've accomplished everything I could on the court."

Not bad, right?

Wozniacki and her hubby recently took classes at Harvard Business School as part of a program that helps athletes build a second career outside of sports ... so post-tennis life has been on her brain for a while.

Congrats!
