In case you missed it, history was made on Labor Day after after three moms advanced to the U.S. Open quarterfinals—the most we've ever seen in any Grand Slam.
Serena Williams, Tsvetana Pironkova and Victoria Azarenka all won fourth-round matches while playing in New York. Williams kicked things off with her victory against Maria Sakkari (6-3, 6-7 (6), 6-3), then Pironkova defeated Frenchwoman Alize Cornet (6-4, 6-7 (5), 6-3), followed by Azarenka's win against Karolina Muchova (5-7, 6-1, 6-4).
The three champions shared their thoughts about the historic moment, as well as their own experiences with balancing motherhood and work. See below for more details.
