Serena Williams US Open 2009 Outburst

Serena Williams was unrepentant and unapologetic after an ugly outburst towards a lineswoman sealed her defeat in the semi-finals at the U.S. Open against Kim Clijsters. The American was beaten 6-4, 7-5 by the Belgian in a match that finished in controversy when she was given a point penalty at match point down after turning on a lineswoman – Telegraph reports. VIDEO!

Towards the end of the second set, the world No 2 was foot-faulted on her second serve, giving Clijsters two match points. That prompted Williams to approach the lineswoman. Gesturing at her with her racket outstretched, Williams hurled a volley of abuse towards her, resulting in the point penalty and the loss of the match.

Speaking shortly after the incident the 27-year-old felt she had nothing to apologise for.

“I don’t think that’s necessary for me to speak about that. I’ve let it go,” Williams said. “I didn’t threaten (her). I didn’t say…I don’t remember anymore, to be honest. I was in the moment. And, you know, everyone’s fighting for every point. It was a really crucial point, 15-30, actually.”

Despite her unwillingness to offer an apology, when asked if she thought the lineswoman in question deserved one, Williams added: “An apology? From me? Well, how many people yell at lines people?” Williams said.

“If you look at all the people that kind of yell at lines people, I think it kind of comes sometimes. Players, athletes get frustrated. I don’t know how many times I’ve seen that happen.”

Television replays were inconclusive as to whether the foot-fault call was correct but Williams said she would be surprised if she had touched the line.

“All year, I’ve never been foot-faulted and then suddenly in this tournament they keep calling foot faults,” she said. “I haven’t been called for a foot fault all year until I got to New York, so maybe when I come to this tournament I have to step two feet back.”
