Serena Williams’ Grand Slam semi-final record

Question

Serena Williams’ Grand Slam title record is well known – she’s been champion at the majors on 11 occasions. But, in bad news for her Australian Open 2010 semi-final opponent Li Na, Serena has a habit of reaching the final of the Slam after she’s reached the last four. In 17 previous Grand Slam semi-finals, Williams has only lost three times.
