WIMBLEDON, England -- Serena Williams has been fined $10,000 by the All England Club for damaging a court during practice before the Wimbledon tournament started.

"I just threw my racquet," Williams said. "I got fined."

When asked what she damaged that deserved a $10,000 fine, Williams said she didn't know.

"I mean, I guess if you could tell me, I would appreciate it," Williams said. "I mean, I have always been an Avenger in my heart. Maybe I'm super strong."

Fabio Fognini was fined $3,000. The Italian said during his third-round loss that he wished a bomb would hit Wimbledon.

Nick Kyrgios was handed two fines, one for $3,000 from the first round and another for $5,000 from the second round -- both for unsportsmanlike conduct. The Australian lost to Rafael Nadal in four sets in the second round.
