The first grand slam of the year begins Monday at the Australian Open in Melbourne and perhaps the most riveting storyline is Serena Williams' bid to make history. Williams is attempting to win a record-tying 24th women's grand slam singles title and is listed at +900 odds by the William Hill Sportsbook to make it eight Australian Open championships. Naomi Osaka (+500) is the betting favorite followed by world No. 1 Ashleigh Barty (+650).

Before you bet, you NEED to see whom Gavin Mair picked. Mair is the international women's tennis expert who called unseeded Jelena Ostapenko (80-1) winning the 2017 French Open, Osaka (32-1) winning the 2018 U.S. Open, Bianca Andreescu (20-1) winning the 2019 U.S. Open, plus many other prescient calls.

Prior to the women's 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. 

Now, Mair has broken down the latest 2021 Australian Open women's odds from William Hill and released his coveted best bets.

In a huge stunner, Mair is fading betting favorite and 2019 champion Osaka's chances of making it two Aussie Open titles in three years because she could face "high-level opposition" in each of the first four rounds. "The draw Gods have not been kind to (Osaka)," Mair tells SportsLine.

Mair is backing a pair of players who could provide excellent value at odds better than +1000. You NEED to see his picks and analysis before you consider placing your Australian Open wagers.
