A tennis legend is calling it quits ... Maria Sharapova just announced she's done with the sport for good.
"Tennis -- I’m saying goodbye," Sharapova wrote Wednesday.
"Tennis showed me the world -- and it showed me what I was made of," the 32-year-old added. "It's how I tested myself and how I measured my growth."
"And so in whatever I might choose for my next chapter, my next mountain, I'll still be pushing. I’ll still be climbing. I'll still be growing."
Sharapova was a former No. 1 player in the world .
