Semi-finals in sight

Much in the same way that rain gets in the way of tennis, work gets in the way of blogging - but thanks to the invention of evenings and the Centre Court roof, we can now get on with both.

Sharapova earlier followed Sabine Lisicki into the next round to form the first semi-final. And now Azarenka and Paszek have decamped to Centre Court to decide who will face Petra Kvitova, who beat Pironkova to reach the second semi.
