The Williams sisters have played 20 times before, and the series is tied, 10-10.
They are 2-2 on grass, with Venus winning in the 2000 Wimbledon semifinals and the 2008 Wimbledon final and Serena winning in the 2002 & 2003 Wimbledon final.
They are 1-1 this year, with Venus winning in the Dubai semifinals and Serena winning in the Miami semifinals. Perhaps the only relevant head-to-head lead is Serena's 5-2 edge in Grand Slam finals, although Venus won their last one.
