NEW YORK, NY, USA - On Sunday, September 9, WTA CEO Steve Simon said: "Yesterday’s US Open final resulted in the crowning of a deserving new champion, Naomi Osaka. The WTA applauds Naomi for her tremendous accomplishment.

"Yesterday also brought to the forefront the question of whether different standards are applied to men and women in the officiating of matches. The WTA believes that there should be no difference in the standards of tolerance provided to the emotions expressed by men vs. women and is committed to working with the sport to ensure that all players are treated the same. We do not believe that this was done last night.  

"We also think the issue of coaching needs to be addressed and should be allowed across the sport. The WTA supports coaching through its on-court coaching rule, but further review is needed.

"Yesterday’s match showcased one of tennis’s new stars as well as one of the greatest players of the game. We look forward to more thrilling matches between these great athletes and hope that what we all witnessed yesterday never happens again."
