Russia's former world No. 1 Maria Sharapova said she could not wait to return to tennis in April after her drugs ban was reduced to 15 months on Tuesday.

"Tennis is my passion and I have missed it. I am counting the days until I can return to the court," the 29-year-old told her fans on Facebook.

Sharapova, a five-time Grand Slam champion, was originally handed a two-year ban — backdated to start on Jan. 26, 2016 — by the International Tennis Federation (ITF) in June following a positive test for the drug meldonium.

"I'm coming back soon and I can't wait," said Sharapova who is now free to return to action on April 26, 2017.
