Olympia Ohanian takes the court in Melbourne

In-between watching her mom win in Melbourne, Serena Williams' three-year-old daughter Olympia is doing her own training.

"I was winning this footrace against Olympia until I pulled something," her father Alexis Ohanian wrote on Twitter.

It appears Olympia is gearing up for a big race against Serena's hitting parter and former University of Virginia standout Jarmere Jenkins.

"Ha! I see you trying to get some practice in Olympia. Make sure you’re ready when it’s go time. #Jarmereisfast," Jenkins wrote. 

Alexis Ohanian Sr. was quick to respond with: "give her a time and a place."

Olympia is also taking to the court more and more. In Melbourne, she got in a quick practice session with Serena's coach, Patrick Mouratoglou.

"It was the only thing that we could do socially distanced for almost a whole year of COVID," Serena said on-court. "I was like, 'I would never put my daughter in tennis!' And then it's the best socially distanced sport that she could play. She has a coach now. It's a lot of fun.

"My three year old has a coach. How ridiculous is that?"

Serena is into the quarterfinals of the hard-court major and is just two matches away from tying Margaret Court for most Grand Slam titles at 24. She has some stiff competition ahead of her.

Serena just defeated No. 2 Simona Halep, 6-3, 6-3, but now she will face world No. 3 Naomi Osaka. If she gets past the three-time champion, she could potentially meet world No. 1 Ashleigh Barty in the final.

Since 1975, only Steffi Graf has managed to go through the Top 3 players in the world to win a Grand Slam title, at the 1999 French Open.
