2021 U.S. Open women's odds, top picks, predictions: Tennis expert avoiding Naomi Osaka in best bets

The 2021 U.S. Open starts on August 30. Ashleigh Barty is the betting favorite in the tournament with +350 odds at Caesars Sportsbook. Naomi Osaka is +450 while seeking a third U.,S., Open title. Iga Swiatek and Aryna Sabalenka are interesting challengers at +1000. Gavin Mair has cashed in huge at previous U,S Open tournaments.

Naomi Osaka won the 2020 U.S. Open in New York and the 2018 edition in Flushing Meadows. Mair doesn't like her value at +450 in pre-tournament betting. She fell in the Round of 16 last week in Cincinnati and she suffered an early exit in Tokyo at the Olympics.

Naomi Osaka is not in Mair's best bets for the 2021 U.S. Open. Mairs has three other players she likes better.
