Williams lost the match and was marred by controversy too. Umpire Carlos Ramos penalized her a point in the second set and thereafter in entire game.
Naomi Osaka won her first Grand Slam title with 6-2, 6-4.
Ramos warned Williams citing that her coach Patrick Mouratoglou gestured hand signals and it was an illegal coaching as per rules. However, the 23-time Grand Slam champion denied it and later was heard demanding apology from the umpire, repeatedly.
She told Ramos, “I don’t cheat. I’d rather lose. Every time I play here, I have problems.”
She was docked with a point following she smashed her racket upon misplaying a shot. Later she called the umpire a thief and was issued a full game penalty.
She was heard saying, “You stole a point from me, and you are a thief.”
Her abusive to a lineswoman in 2009 led her docking a point. Her opponent Sam Stosur was awarded a point in 2011 due to her yelling, “come on” to Stosur, who found disturbing while making contact with ball.
US Open meanwhile said decision of Ramos was not reviewable.
It said, “There are matters that need to be looked into that took place during the match.”
However, at the end, after victory of Osaka, Williams said the Japanese player deserved the win and let everyone give her credit. She congratulated her too.
