loses quarter-final duel to American Sam Querrey

Murray's defence of his Wimbledon title came to an end with a quarter-final defeat by Sam Querrey.

The result might have been different had Murray capitalised on a lead in the second set but, although he won the third, the physical stress took its toll and the Scot fell to a 3-6 6-4 6-7 (4/7) 6-1 6-1 loss.

But Murray will at least keep hold of his No.1 ranking after Novak Djokovic retired from his match against Tomas Berdych.

The defeat is Murray's worst ever at Wimbledon in terms of his opponent's ranking, having previously never lost to a player ranked lower than world number 19 David Nalbandian, on his debut in 2005.

Querrey, ranked 28th, becomes the first American man to reach the semi-finals at a grand slam in singles since Andy Roddick here in 2009.

He has now accounted for the defending champion 

in each of the last two years at Wimbledon, after beating

 Djokovic in the third round last year.

The faces of their partners said it all.
