Bizarre situation involving Serena Williams -- who damaged a Wimbledon tennis court during a pre-tourney practice session ... and now she's been ordered to cough up $10,000 in fines.
Unclear exactly what Serena did to warrant the fine -- though some reports say she used her racket to inflict the damage during a Sunday workout.
The All England Club -- the organization which hosts Wimbledon -- has meted out a $10,000 fine for Serena which is chump change for her considering she's already made $367,000 for making the quarterfinals.
So far, Serena hasn't commented on the fine ... but she's never been shy to speak her mind if she feels she's been wronged.
She's set to play Alison Riske on Tuesday -- and there's no doubt she'll be asked about the incident by the media either before or after the match.
Of course, many consider the grass courts at Wimbledon to be sacred ... which explains the hefty fine.
