Sorry if there is a thread, I did scan four pages to check.
Serena gets coached (which her coach admits) but claims she didn't see it. Then smashes a racquet in separate fit of temper. Then tells the umpire she can't be a cheat because she's a mother(!), he will never referee a match again with her, and he's a thief.
The punishments all seem fine to me and I really felt for Osaka having to apologise in her winners speech. Serena should be saying sorry today IMO.
