WTA chief backs Serena as row grows over US Open 'sexism'

Serena Williams's claim that the code violations that sparked her meltdown in the US Open final were sexist stirred debate, with WTA Tour chief executive Steve Simon backing her on Sunday.

Williams was handed three code violations -- and docked a point and then a game -- in her 6-2, 6-4 loss to Naomi Osaka in the Flushing Meadows final.

Osaka out-played her childhood hero to become the first Japanese player to win a Grand Slam, but her accomplishment was swamped in the controversy surrounding 23-time Grand Slam champion Williams.

The American superstar claimed that chair umpire Carlos Ramos meted out penalties for infractions that male players could have gotten away with, specifically a violation for verbal abuse after she called him a "thief" and a "liar" for warning her for coaching from her players' box, then docking her a point when a racquet abuse violation followed.

Eventually she was docked a game -- putting Osaka on the brink of victory.

Simon said the affair 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," he said.

"We do not believe that this was done last night." Williams was most incensed by the first code violation she received -- for coaching from her box.

It's not clear if she even saw the hand gestures by coach Patrick Mouratoglou sitting her box, although he admitted in an interview with ESPN that he was trying to advise her -- and said all coaches do it.
