I got fined," Williams said."I mean, I guess if you could tell me [what the damage was], I would appreciate it. I mean, I have always been an Avenger in my heart. Maybe I'm super strong, I don't know."Williams will face Barbora Strycova in the last four after the Czech ended Johanna Konta's hopes with a 7-6 (5), 6-1 triumph on Centre Court.
