LONDON: Gilles Muller's unlikely Wimbledon run came to an end when he was beaten in five sets by Croatian Marin Cilic in their quarter-final on Wednesday. Cilic, who triumphed 3-6 7-6(6) 7-5 5-7 6-1 will now face Sam Querrey in the semi-finals after the American upset home favourite Andy Murray. The 34-year-old Muller was an unexpected presence in the last eight after he pulled off a surprise, five-set win over Rafa Nadal in the fourth round. Muller took that form into the contest with Cilic but when his run of 31 service games without a break ended in the third set, the tide turned towards the Croat, who produced some magnificent return play in the final set.
