The 36-year-old turned out alongside sister Venus in a doubles clash against the Netherlands at the Fed Cup in North Carolina on Sunday, just five months after giving birth to daughter Alexis Olympia Ohanian.
On Sunday, Serena reunited with her sister, Venus, where they played a doubles match that resulted in a loss to Dutch duo Lesley Kerkhove and Demi Schuurs.
Serena Williams may make jaws drop when she plays tennis, but her adorable baby daughter Alexis Olympia is making hearts melt on the court. "It gave me a lot of pressure for me to close it out and a lot of pressure for her to stay in and I just handled it a little better".
Venus credited team-mate CoCo Vandeweghe, who scored a hard fought win over Hogenkamp the day before, for paving the way."Honestly I like to think CoCo wore her down some". "I feel like I'm on the right track for me".
Early in the match Serena showed the effects of her lengthy layoff, perhaps most noticeably when she shanked a routine volley that left her bent over in embarrassment.
John Stamos and Caitlin McHugh Are Hitched!
Stamos stars in Netflix's " Fuller House " and spent part of past year with The Beach Boys as a drummer. I know they would love her. "We have the same morals and the same values, that all clicked nicely".
Serena was scheduled to compete in the Australian Open this January, but chose to pull out after losing an exhibition match in December.
In Prague, Petra Kvitova sent the Czech Republic into their 10th consecutive semi-final when she clinched the first round tie against Switzerland with a 6-2 6-4 win over Belinda Bencic in the third rubber. Both were in attendance over the weekend, seated just behind the players' box. I'm going to try to do better.
"I didn't manage my time well", she said.
"Serena's gonna be joining her sister Venus!" she announced, to roars of approval before the superstar appeared dressed in a white top, dark blue shorts topped off with a red headband.
She had initially targeted last month's Australian Open and a defence of her 2017 title but struggled during an exhibition match against Jelena Ostapenko in Abu Dhabi in December, forcing her to revise her plans.
