Serena Williams' racket-smashing, verbal tirade at the US Open last night will apparently cost her $10,500, the New York Times reports. The United States Tennis Association levied the fine today for unsportsmanlike conduct and racket abuse, but will let her play her doubles match with Venus tomorrow. Venus practiced with her father today, but Serena was nowhere to be seen. “I would be utterly shocked if they don’t" play, says a retired player who works for CBS. “The best antidote for something like this is to get right back on the court.”
