Comeback queen Kim Clijsters produced a massive upset to defeat title holder and tournament favourite Serena Williams 6-4,7-5 in the US Open semi-finals.
The match had a chaotic ending with Williams handed a point penalty for verbally abusing and threatening a lineswoman who foot-faulted her to set up match point.
Williams had earlier drawn a warning for smashing her racquet to the ground after losing the first set. The second warning was an automatic point penalty,which just happened to come on match point.
“I said something and I guess they gave me a point penalty and unfortunately it was on match point,” she said.
“Clearly in all this year I’ve never,never been foot-faulted and suddenly in this tournament they give me foot faults.
“I’m not saying I don’t foot fault,but it was what it was.
