Tennis umpires reportedly mulling boycotting Serena Williams matches after US Open flap

"Mr. Ramos" decisions were in accordance with the relevant rules and were reaffirmed by the U.S. Open's decision to fine Serena Williams for the three offences'.

Naomi Osaka shows off her US Open prize at the Rockefeller Center in NY.

She said: "My favourites are Serena [Williams] and [Roger] Federer".

"Ramos is tough, one of the best umpires in the world", Strycova said.

"I don't understand from where he's coming with that statement", said Djokovic, suggesting this was the first he has heard of umpires failing to treat men and women equally.

The Japanese player's breakthrough triumph in NY was overshadowed by an explosive row between her opponent Williams and umpire Carlos Ramos which resulted in the 23-times Grand Slam champion being docked a game and fined $17,000.

"I'm fine, given the circumstances", he told the publication.

"I thought about those things watching Serena, and I said, 'This kid has been playing all of these years, and I don't think she's ever been accused of cheating before it happened on Saturday.'" he said, "And [tennis coaches], they all cheat, no matter how you look at it".

Williams' defeat came after she was issued a code violation for receiving coaching, a common practice in the sport.

Britain's Jamie Murray has rejected claims of men being treated more leniently than women by umpires.

The International Tennis Federation stood by Ramos' stance and praised him for acting with "professionalism and integrity".

Williams claimed Ramos' actions in NY were "sexist" but speaking to BBC Sport yesterday, US Open mixed-doubles champion Murray said: "I think that's a bit far-fetched".

Osaka's success has brought to light her off-the-court sense of humour. "I'm not going to say, 'Oh, I can't draw that because that's a no-go area.' What does that say about the way the world's going?"

Serena Williams of the United States yells at chair umpire Carlos Ramos at the 2018 U.S. Open tennis tournament at USTA Billie Jean King National Tennis Center, Sept. 8, 2018. "Don't worry about me", Ramos said while speaking to Portuguese newspaper Tribuna Expresso, according to The Associated Press. "It's a delicate situation, but a la carte arbitration does not exist". You owe me an apology. But Powell tells Marketing Daily he thinks it is likely: "Brands are smart to share their core values with their consumers", he says.
