The third major of the year, Wimbledon 2021, begins Monday, June 28 from the All England Lawn Tennis and Croquet Club in London after the 2020 tournament was canceled due to the coronavirus pandemic. World No. 1 Ashleigh Barty is the 6-1 favorite in the latest 2021 Wimbledon odds by William Hill Sportsbook, followed by Serena Williams (7-1), Garbine Muguruza (9-1), Bianca Andreescu (10-1), Iga Swiatek (10-1) and Petra Kvitova (10-1). 

Reigning champion Simona Halep is listed at 12-1 while Barbora Krejcikova, who won the French Open earlier this month, is 33-1.

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, Naomi Osaka (32-1) winning the 2018 U.S. Open, Andreescu (20-1) winning the 2019 U.S. Open, plus many other prescient calls.

Prior to the women's final in last year's French Open, Mair picked Swiatek to win (-163) and do so in straight sets (+140), and he was right on both counts. 

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

In a huge shocker, Mair is fading the favorite and top-ranked women's player in the world, Barty, because of the uncertainty surrounding the health of her hip.

"(Barty) retired at the French Open due to a hip injury and has not played since," Mair told SportsLine. "The Australian is well known for playing tournaments to build her form and confidence, but she has been prevented from having the ideal preparation for this year's Wimbledon."

Mair has locked in his best bets, and they include a long shot who would bring HUGE returns. He's especially high on an enormous long shot who "has long been touted as a potential Grand Slam champion!" You NEED to see his picks and analysis before you make any 2021 Wimbledon picks of your own.
