Tennis superstar Serena Williams has announced that she will be returning to competition after taking almost a year off for various health reasons.

The 29-year-old American and 13 time Grand Slam Champion was diagnosed in February with blood clots in her lung. After that, she said she needed treatment for a hematoma on her stomach. She has not competed or practiced since.

Serena announced she will return for the grass court tournament in Eastbourne, England and then defend her title as Champion in Wimbledon, starting June 20th.

In a statement released by her agent, Serena had this to say:

"I am so excited to be healthy enough to compete again. These past 12 months have been extremely tough and character building. I have so much to be grateful for. I'm thankful to my family, friends, and fans for all of their support. Serena's back!" -

At Wimbledon, the Williams sisters have combined to win nine of the past 11 championships. In that time, the sisters played each other in four of the finals at the competition.
