Serena Williams said she wants to make her daughter proud after fighting back to reach the French Open third round.
The 36-year-old American came from a set and break down to defeat Australia's Ashleigh Barty 3-6, 6-3, 6-4.
The three-time champion and former world number one, dressed again in her all-black catsuit, is playing her first Slam since winning the 2017 Australian Open while two months pregnant.
However, her stay in Paris almost proved short-lived until she summoned the same fighting spirit which helped her conquer life-threatening blood clots after giving birth to daughter Alexis Olympia Ohanian in September.
"It's just incredible," said Williams.
"I am so happy to be back here. I lost the first set and thought I must try harder, I must try harder -- and then Serena came out.
"I will be back tomorrow to play doubles with Venus. I don't mind playing singles and doubles -- I will fight my heart out."
"However, my outfit is actually functional for me, because I had a lot of health issues."
