Andy Murray survives Gilles Muller test

The Brit was outplayed in the opening set as some brutal serves and groundstrokes saw Muller storm into the lead.

A cagy second set failed to produce a single break point as it went to a tie-break, with a fired up Murray snatching an early mini-break with a neat forehand down the line – the catalyst for the top seed to restore parity.

An early break in the deciding set was ultimately enough as Murray marshalled his opponent with a full armoury of shots to seal victory in one hour and 56 minutes.

The world number three will face Viktor Troicki in the semi-finals after the Serb beat John Isner 7-6(5) 6-3 in Friday's evening encounter.

“He started well and I didn’t quite know what to do on the return game,” Murray told Eurosport.

“But when I started to return better, he seemed more anxious to come into the net and I was able to get myself into the rallies. It’s a good win for me.”

Murray also played down a possible hamstring injury, insisting that his concern was merely precautionary with Wimbledon on the horizon.

Earlier, third seed Milos Raonic became the latest casualty in London after losing 4-6 6-3 7-5 to France’s Gilles Simon.

Simon will contest a final spot with South Africa’s Kevin Anderson, who edged Guillermo Garcia-Lopez 7-6(7) 7-5.
