First, Williams was issued a warning from chair umpire Carlos Ramos for a coaching violation, which Williams swore was illegitimate.
Patrick Mouratoglou admitted to coaching Serena Williams during the U.S. Open final, but believes she never received his message.
Afterwards, Williams said Ramos had never taken a game from a man for calling him a thief and referenced Alize Cornet being given a code violation for changing her shirt on court earlier in the tournament as an another example of double standards within the game. She dreamed when she was younger of playing Williams in a Grand Slam final, earning her chance with a Williams-esque waltz through the draw in which she's dropped just 28 games over six matches.
Asked how she did it, she replied: "This is going to sound really bad but I was just thinking, "I really want to play Serena".
The ice-cool Naomi Osaka triumphed 6-2 6-4 at Flushing Meadows to become Japan's first grand slam singles champion, yet that huge achievement was overshadowed by sensational scenes of anger on the other side of the net. "Even though I'm not a spring chicken I still have a very, very bright future", she said.
Osaka said: "She beat me 6-0 until I was 15, and then, I don't know what happened, but one day I beat her 6-2".
Osaka would win on her next service and take home the title.
Mouratoglou said he had attempted to help Williams, but added coaching was common in nearly every match.
LA district attorney won't file charges against Kevin Spacey
Seagal's attorney Anthony Falangetti denied the accusations on behalf of his client in a statement to ABC News. But, Los Angeles prosecutors say they couldn't take the case forward because too much time had passed.
Despite her dominant display, Serena estimated she is still only operating at 50-60 per cent and then fired an ominous warning to her fellow players.
Billie Jean King, the namesake of the tennis center where the U.S. Open is now played, fought for prize parity in the '70s. She brought Osaka to net and served with more consistency, keeping pace with the 20-year-old phenom.
"I was on the far other end, so I'm not sure".
Osaka was nervous Saturday, making a few phone calls to her sister in Paris to calm her down.
Tournament officials announced that because of a high probability of rain from the afternoon through evening, the roofs at Ashe and Louis Armstrong Stadium had been closed and would stay that way for the remainder of Saturday's play.
Williams held, but Osaka was able to do the same in her next service game to win the set and the match.
What was most problematic for Williams on the scoreboard was that she was unable to keep up with a version of herself.
She will now meet 23-time slam singles champion Williams, who won her first title in NY 19 years ago and thumped Anastasija Sevastova prior to Osaka's win over Keys on Thursday.
Like her previous two matches, Williams got off to a slow start.
