Five-time Grand Slam champion Maria Sharapova has announced her retirement.

“Tennis — I’m saying goodbye,” she wrote in an essay that appeared Wednesday in Vogue and Vanity Fair.

Sharapova turned pro in 2001 at age 14. She won Wimbledon in 2004, the US Open in 2006, the Australian Open in 2008 and the French Open in 2012 and 2014.

She lost in the first round of this year’s Australian Open to Croatia’s Donna Vekic in straight sets. She played only two matches this season and lost both.
