Naomi Osaka is the US Open champion. Japan's first Grand Slam winner.
But that is only half the story.
This match will be remembered for Serena Williams' outbursts. She was given a violation for coaching, racquet abuse and verbal abuse to the umpire. She was docked a point and a game. She called the umpire a "thief".
Extraordinary end to the press conference as Williams starts to get emotional after insinuating it was sexist behaviour from Carlos Ramos.
“I’ve seen other men call other men other things. It made me feel it was a sexist remark. He’s never taken a game from a man for being called a thief.”

Here's a reminder of what happened between Serena Williams and the umpire during the match.
First Serena Williams was given a code violation for coaching when her coach Patrick Mouratoglou appeared to make a gesture to her.
Serena argued with the umpire saying "I don't cheat" and then the game resumed.
A few games later Serena Williams smashed her racquet after losing a game. She was given a violation. This one meant Osaka was awarded a point.
Serena then argued with the umpire again. She said "you owe me an apology" among other things.
Serena argued again and called umpire Carlos Ramos a "thief".
As a result Ramos gave Serena another violation for verbal abuse. This meant Osaka was awarded a game.
Serena then called for the tournament referee and was crying on court.
No further action was taken by the referee and two games later Osaka sealed the win.

Never seen a press conference so packed. Serena is here.
Every seat taken in the main interview room, journalists and photographers are stood in every available space.
“I don’t know how I’m feeling yet,” she said. “I’m trying to stay positive.”
“Maybe the mom in me said we have to pull ourselves together.”
