The moms are dominating at this year's US Open. Victoria Azarenka, who has not seen a round of 16 at the major since 2015, moved on after a strong performance against Iga Swiatek.

The former world No. 1 pushed aside Swiatek, 6-4, 6-2, in just 97 minutes. Azarenka has been playing stellar tennis, starting with a title win at the Western & Southern Open and now moving towards her third career Grand Slam title. "Cincy" was her first trophy raised as a mom after having Leo in 2016.

During this year's US Open,  the two-time Australian Open champion has only dropped seven games.

Yet she's still finding time to enjoy life within the bubble with her son. The pair cheered on Naomi Osaka during her third round match against Marta Kostyuk.

If Azarenka can beat No. 20 seed Karolina Muchova on Monday, the 31-year-old will find herself in the quarterfinals against her toughest opponent yet, No. 2 seed Sofia Kenin.
