Three moms continue to rule the US Open

Moms have been ruling the US Open this year with three taking the court for the round of 16 on Monday, and all three winning. Serena Williams, Victoria Azarenka and Tsvetana Pironkova are flipping the script on what's possible for moms everywhere.

It's been fun for spectators to watch with two of the tennis children on site and making a few appearances. Azarenka's three-year-old son Leo has been rocking an adorable hair style while watching matches.

There were nine mothers in the draw at the start of the tournament, which Azarenka called "pretty incredible".

"But identifying myself or other players just as mothers, I think that's not the only thing that we are," she told press. "I think we are part of being a mother, we are also tennis players. We are also women who have dreams and goals and passions."

Serena's three-year-old Olympia Ohanian has been a part of the tour since she was born. Fans have gotten to watch her grow up.

She's been accompanied around the site by her dad Alexis Ohanian, who has sported a cute Girl Dad mask.

Pironkova might be the lesser-known mother of the trio and her son has to watch her on TV, but she's making him proud. She left the tour in 2017, had her son Alexander in 2018, and is playing in her first tournament back.

"Everything change," she said. "Your priorities have nothing to do with what they did before. Nothing is the same really. Right now I'm just happy to be playing. Having the opportunity for him to watch me also makes me really happy."

Pironkova has ousted two seeds so far, Garbine Muguruza and Donna Vekic, and she'd take out Alize Cornet to reach the quarterfinals to set up a mom showdown with Serena (who beat Maria Sakkari). Azarenka fought past Karolina Muchova and will face Elise Mertens.

No matter what happens, the moms will have a toddler's eager open arms waiting for them after they get off the court, or get home.
