"It’s been over a year and a kid later and I get to go home to her now, and I’m excited about that," the tennis superstar continued. "It definitely wasn’t easy. We always have a couple tight sets. It was good. I’m a little rusty, but it doesn’t matter. I’m just out here on this journey and doing the best I can."

Before getting back on the court, Williams celebrated on social media her return to tennis after the 14-month break.

It's official. My comeback is here. This Thursday I will start playing tennis again professionally for the first time since giving birth to my daughter. This whole month I am playing tournaments in California and Florida- both my home states. Thursday, the day I play my very first match, marks international women's day. My comeback could not have come on a better day and I decided I wanted to do something different let you all be apart of my long journey back (if you want of course!!) So I created my Serena Gold toned "S" pin. When I am playing you can wear it and show support not only from me but also for my charity which supports the Yetunde Price Resource center. I want this gold "S" mean something special to you personally. What is one S word in your life that means something to you? Mine is Strong and Sure! So when I wear my "S" pin I am representing Strength, and Sureness. What would your "S" mean? They are for now only available for my fans that come see my at Indian wells, and Miami starting Wednesday as well as Thursday when I play!! Sooooo if you are watching me stop by the Serena booth to grab a "S" pin. Post pics of you wearing your "S" and tag me! Thanks for the support I look forward to seeing you out there!!

During her break, the tennis star had her hands full. Not only did she and her now-husband, Reddit co-founder Alexis Ohanian, welcome their daughter, Alexis Olympia Ohanian Jr., six months ago, they also exchanged vows last November.

Ohanian also celebrated his wife's return to the court on social media.

"#GMOAT [Greatest mother of all time] back to work tonight," he wrote in a caption on Instagram. "Strong W, especially after everything you've been through. I'm so proud of you."
