I think for me I am in the middle on this one. I mean the first call was kind of questionable. I mean I personally don't think she uses it, with that said, the umpire saw the give a hand signal. So he was right to give a warning. Then Serena broke her racquet, clearly she caused that, and almost every chair calls that. So she clearly caused the point penalty. I mean she had to know this. My issue comes on the third . I really have a tough time on her being given this. She kept telling him you owe me an apology, used the word liar and thief. I'm sorry, I just don't feel it warranted it. She didn't aware, she didn't threaten him. Its unfortunate the match went this way.
Clearly Osaka was out playing her, and yes I think Serena should have kept it together. You're a pro tennis player who is suppose to be a role model. And a role model needs to act accordingly.
The issue for me is that I think the third call was unfair to both players and did affect the match
