Serena Williams has withdrawn from the Fed Cup by BNP Paribas Final between Italy and USA, taking place in Reggio Calabria on 7-8 November.
Williams, who has been competing at the season-ending Sony Ericsson Championships in Doha, will be replaced by Vania King.
King made her Fed Cup by BNP Paribas debut against Germany in 2006 and has played in five ties, compiling a win-loss record of 4-5. She currently holds world rankings of No. 78 in singles and No. 32 in doubles.
King, 20, has won seven career doubles titles, two of which coming this year in Brisbane and New York. On the singles court, her sole tournament victory came in Bangkok in 2006.
Captained by Mary Joe Fernandez, USA’s team will now be King, Melanie Oudin, Alexa Glatch and Liezel Huber, the world’s top doubles player.
