New York - The US Tennis Association says Serena Williams has pulled out of the team that will face Italy in the Fed Cup final.
USTA spokesperson Chris Widmaier said on Saturday that Williams informed United States captain Mary Joe Fernandez she won't play in the November 7-8 matches.
Vania King replaces Williams on the roster, joining surprise US Open quarterfinalist Melanie Oudin, Liezel Huber and Alexa Glatch.
Fernandez had announced this week Williams would play Fed Cup for the first time since 2007.
Williams leads active women with 11 Grand Slam singles titles and is unbeaten in Fed Cup singles play. She is in this weekend's semi-finals at the season-ending WTA championships in Doha, Qatar.
