Serena Williams has been fined a record $82,500 for her tirade at this year's US Open and could be suspended from that tournament if she has another "major offense" in the next two years.
Grand Slam administrator Bill Babcock says Williams faces a "probationary period" at Grand Slam tournaments in 2010 and 2011.
If she has another incident at a major championship in that time, the fine would increase to $175,000 and she would be barred from the following US Open.
Babcock said the previous highest fine for a Grand Slam offense was about $48,000 to Jeff Tarango in the 1990s.
Williams lashed out at a lineswoman after a foot-fault call at the end of her US Open semi-final loss.Reuse content
