Osaka, Kenin, Swiatek pull out of WTA Montreal Open

The tournament begins on August 9 and will serve as a tuneup for the US Open, that starts on August 30.

Osaka is coming off a third-round loss at the Tokyo Olympics.

Naomi Osaka pulled out of the National Bank Open hard-court tuneup to be played in Montreal this month ahead of the US Open.

The tournament announced the withdrawals of Osaka and two other top-10 players who have won Grand Slam titles, Sofia Kenin and Iga Swiatek, on Tuesday.

Osaka is coming off a third-round loss at the Tokyo Olympics, where she had the honor of lighting the cauldron during the opening ceremony.

Before that, the 23-year-old Osaka had not competed anywhere since withdrawing before her second-round match at the French Open, citing the need for a mental health break.

The fourth-ranked Kenin, who won the 2020 Australian Open, has been sidelined by a foot injury since Wimbledon. No. 8 Swiatek, last year's French Open champion, lost in the second round of the Olympics. The tournament begins August 9.
