After the victory, Pegula wrote on the on-court camera in celebration: “Bills you’re next.”
Pegula, 27, tweeted about wearing Bills’ colors during her time in Melbourne earlier in the week.
“Coincidence I’m in Bills colors?” she wrote.

Pegula recorded her best career major result at the 2021 Australian Open with a run to the quarterfinals before losing to eventual finalist and fellow American Jennifer Brady.
The 24th-seeded Azarenka won the title at Melbourne Park in 2012 and 2013, and she also has been the runner-up at the US Open three times, most recently in 2020. She next will play No. 4 Barbora Krejcikova or No. 26 Jelena Ostapenko, who each has won the French Open.
Since a quarterfinal run in Australia in 2016, Azarenka lost first-round matches last year and in 2019 and missed the hard-court tournament in 2017, 2018 and 2020.
