Before you make any Pegula vs. Brady or 2021 Australian Open women's quarterfinals picks, you MUST see what Gavin Mair has to say.

Mair is the international women's tennis expert who called unseeded Jelena Ostapenko (80-1) winning the 2017 French Open, Naomi Osaka (32-1) winning the 2018 U.S. Open, Bianca Andreescu (20-1) winning the 2019 U.S. Open, plus many other prescient calls.

Before the women's singles final in the most recent Grand Slam, the French Open, Mair picked Iga Swiatek to win (-163) and win in straight sets (+140), and he was right on both counts as the 19-year-old beat Simona Halep for her first title.
