Andy Murray has said that preparing for his match against Jo-Wilfried Tsonga yesterday was tough because of the implications for the tournament's semi-finals.

The US Open champion needed to win just one set to secure his place in the last four, while a straight sets win for the Frenchman would have seen him progress instead.

The Scot told Sky Sports News: "It's quite a tough scenario when you know if you lose in straight sets he is in.

"I needed to win one set so I was lucky I got off to a good start and then, at the end of the second set, there was some good tennis and long rallies. That was nice."

Murray joins Roger Federer and Novak Djokovic in the semi-finals, with the fourth place to be decided by today's matches.
