I think it was unfair to Serena. I also don’t understand the coaching rule. I’m not very familiar with tennis rules. I don’t see why a pro needs coaching during a match, but I also don’t understand why her coach thinks it’s ok, when it’s against the rules and is citing, “well, the others do it so it should be ok.” Everyone should be following the rules, if the rules are stupid then get them changed. I think Serena really showed grace in the end by quieting the crowd and comforting Osaka. I felt badly for Osaka, she didn’t want to win that way I’m sure.
