Safina battles back against Lisicki

Top seed Dinara Safina recovered from a set down for the second day running to book her place in the Wimbledon semi-finals with victory against German teenager Sabine Lisicki.

Lisicki had already knocked out fifth seed Svetlana Kuznetsova and ninth seed Caroline Wozniacki to reach the quarter-finals, and threatened another upset after taking the opening set on Centre Court.
