First warning: coaching violation. Rule broken, not a big deal. Her coach acknowledged that he was trying to coach her (made no sense to me), but said that everybody does it, and it never gets called. So what? Tell that to the state trooper who pulls you over for speeding, and see how it works out. Second warning - She broker her racket in a fit of rage on the court, and it cost her a point - rule broken (not always enforced), cost her a POINT. B.F.D. Third incident: She called the umpire a "THIEF," and it cost her a game. All in accordance with the rules. Many tennis players, mainly men, exhibit childish behavior, throwing tantrums on the court, but usually directed as SELF, so often are tolerated. But rules are rules, and Serena knows them. Her behavior on the first two calls was outrageous. "YOU OWE ME AN APOLOGY!"????? Who does she think she is? An apology for enforcing the rules against her? Gimmeafukkinbreak. Then she tells the umpire he is a "thief." He stole a point from her because she is a woman. This crosses a huge line in sports. You can tell an official he is blind, he made a mistake, he is incompetent, or you hate him. You cannot challenge his integrity. She should have been disqualified and tossed out of the tournament. This is the sort of thing that cannot go un-corrected. Then she tells an interviewer that she was fighting for her principles? What principle, exactly, was that? That if you are a Big Fucking Star you are untouchable, and the rules shouldn't apply to you? And by the way, she was getting her ass kicked and would have lost the match anyway. The Media has already decreed that she was grievously wronged, and had the win taken from her unfairly. Bullshit. Hopefully Osaka will have many more wins and Grand Slams before too much longer, and this incident will go down in tennis history as the nothing-burger that it really was. It really didn't affect the outcome of the match.
