The Australian tennis player Samantha Stosur booked her semi-final spot at the WTA Charleston clay court event with a pair of three-set wins today, ruining the prospect of an all-Williams clash.
Second seed Stosur finished off Galina Voskoboeva in their held over third round match before returning to the court 2 hours later to beat world number 87 Venus Williams with a 6-3 4-6 6-3 win in the quarter-finals to set up a semi-final showdown against Serena Williams.
It has only happened eight times that a WTA player has defeated both Williams at the same tournament: 1998 Sydney (Arantxa Sanchez-Vicario), 1999 Sydney (Steffi Graf), 2001 Australian Open (Martina Hingis), 2002 WTA Championships (Kim Clijsters), 2004 Los Angeles (Lindsay Davenport), 2007 US Open (Justine Henin), 2009 US Open (Clijsters) and 2010 Rome on clay (Jelena Jankovic).
