London: World No 1 Serena Williams has been fined $175,000 (Dh642,250) and put on probation for two years for her foul-mouthed tirade at the US Open, the Grand Slam Committee said on Monday.
The committee said a further major offence at a grand slam in the next two years would see her suspended from the US Open in 2010, 2011 or 2012. The fine will be reduced to $82,500 if she commits no further major offence through 2011.
"On 9 November 2009, the Grand Slam Committee administrator determined Serena Williams had committed the grand slam major offence of aggravated behaviour for her misconduct at the 2009 US Open," the committee said in a statement.
The committee, who are responsible for organising the four grand slam events, met on Saturday at the World Tour Finals in London to discuss administrator Bill Babcock's recommended punishment.
Williams' outburst was prompted by an incident in her semifinal against eventual champion Kim Clijsters at Flushing Meadows in September.
Trailing 4-6 5-6 15-30, Williams launched into a second serve but the line judge called her for a foot-fault, meaning the American had served a double-fault to go match point down.
