Unfortunate ending to the first women's semi final earlier tonight as Peng Shuai retired from the match and had to leave the court in a wheelchair.
She was losing 6-7 3-4 to Caroline Wozniacki when she called for a medical timeout and left the court for a few minutes after appearing to be in a lot of discomfort. She came back and played a few points before collapsing to the ground and, after a few minutes, she was eventually helped up into a wheelchair and taken off court as Wozniacki was announced the winner.
Hope she's ok.
Wozniacki will play either Serena Williams or Ekaterina Makarova in Sunday's final. They are playing at the moment and Serena has just taken the first set 6-1.
