Former World No.21 Aleksandra Wozniak announced her retirement effective immediately on Wednesday.

“The past few years have been challenging with all of the injuries, but I always continued to fight because I was still passionate about my sport,” she said. “Today, I love tennis just as much, but due to my injuries, my body is no longer able to perform at 100%. It is time for me to turn the page."

Wozniak scored her career-high ranking just under a year after her first WTA title, earned at the former Bank of the West Classic (Stanford) in 2008. The Canadian knocked out Francesca Schiavone, Serena Williams (via retirement) and future Wimbledon champion Marion Bartoli in the final.

"I took the time to think carefully before making this decision. I am now ready to live new experiences."

She later finished runner-up to Caroline Wozniacki at a French Open warm-up event in Pontra Vedra Beach, and reached the Round of 16 at the 2009 French Open that same year.

Her best result at home came at the Rogers Cup in 2012, where she made the quarterfinals after wins over Daniela Hantuchova and former World No.1 Jelena Jankovic.

The fourth-highest-ever ranked Canadian woman, she holds her country's record for most wins (40), most singles wins (32) and most ties played (36). She also took part in the 2012 London Olympic Games.

"I don’t know what awaits me, but I would love to be able to give back to my sport, since it has given me so much over the years.”
