2021 Australian Open women's odds, picks, predictions: International tennis expert fading Naomi Osaka

Serena Williams has gone three years without winning a grand slam singles title. She will play in the 2021 Australian Open at Melbourne Park in Melbourne. William Hill Sportsbook lists Williams and Aryna Sabalenka as the co-third choices in latest 2021 Australia Open odds at +900. Naomi Osaka, 2019 Australian champion, and world No. 1 Ashleigh Barty are the top two picks on the tennis odds board.

No. 3 seed Naomi Osaka is the betting favorite for the 2021 Australian Open. Mair is not including her in his bets. Osaka's quarter of the draw has six major champions, including Bianca Andreescu and Angelique Kerber. She is on a 14-match winning streak.

Gavin Mair has made his best bets for the 2021 Australian Open women's tennis tournament. He has called long shots winners of three grand slam women’s titles since 2017.
