Women's US Open Odds: Oddsmakers, Bettors Torn On Ashleigh Barty vs. Naomi Osaka

The betting for the Men's side of the US Open is completely one-sided. Bettors, and oddsmakers for that matter, have made up their mind that Novak Djokovic will win it all, making it four Grand Slams for Djokovic in a calendar year.

But, the Women's US Open odds and betting haven't painted such a clear picture.

According to oddsmakers, the world's No. 1 player, Ashleigh Barty, is most likely to win the upcoming US Open. Barty is fresh off a win at Wimbledon and has been playing the best tennis in the world of late. But the betting public has their eyes on another choice.

It's been a bit of a bumpy ride for Naomi Osaka lately, but she's the most popular pick to win the US Open. Osaka withdrew from the French Open earlier this year. Then, right before Wimbledon, she informed the world she would not be participating. In her next international appearance, the 2021 Tokyo Olympics, she was upset in the third round.

Still, despite all the recent troubles for Osaka, bettors have faith she will win the US Open this year, even if the US Open odds favor Barty.

US Open Odds - Women's Tournament

Ashleigh Barty, while not having the same kind of name recognition as Osaka, is indeed the best tennis player in the world right now. So, it shouldn't be a real shock to see that the latest US Open odds have her as the favorite.

Barty won the last Grand Slam in which she appeared, defeating Karolína Plíšková (6–3, 6–7, 6–3) in the Finals of Wimbledon. But, she's also struggled a bit in Grand Slams in the past.

Barty, at age 25, has qualified for 25 Grand Slams in her career. She's only made it into the quarterfinals in five of those appearances and is 9-5 in her career at the US Open.

Still, she's in great form and deserving of the top spot.

Meanwhile, Naomi Osaka, at age 23, has already won two US Opens and racked up an impressive 21-3 record in five appearances at Arthur Ashe.

Barty's +450 US Open odds imply an 18.2% shot she wins the tournament. Osaka's odds sit at +600, implying a 14.3% chance she does the same.

Tennis Player US Open Odds Implied Probability
Ashleigh Barty +450 18.2%
Naomi Osaka +600 14.3%
Aryna Sabalenka +1400 6.7%
Iga Swiatek +1700 5.6%
Karolina Pliskova +1700 5.6%
