Andy Murray has said that his shock first-round exit at Queen’s Club to Australia’s Jordan Thompson was a “big blow” ahead of his Wimbledon title defence.

Murray faced Thompson after fellow Briton Aljaz Bedene withdrew with a wrist injury. Lucky loser Thompson took his place and pulled off an astonishing upset in temperatures of almost 38 degrees.

Thompson was playing high risk tennis when he won the first set on a tie-break and he then raced through to second to secure victory and knock Murray out of the tournament in the first round.

Afterwards Murray said, “Yeah, a big blow, for sure. Obviously this tournament has given me great preparation in the past, and when I have done well here, you know, Wimbledon has tended to go pretty well, too. It’s not ideal obviously, but guys have in the past also gone into Wimbledon having not won lots of matches. You know, Novak [Djokovic] a number of times hasn’t played any warm-up tournaments and played very well there.”

He insisted that there is no guarantee that he will play badly at Wimbledon but conceded that it would have helped to play some more matches.

Thompson ended Murray’s 14-match winning streak on grass and his 10-match unbeaten run at Queen’s.

It looked as if Murray was back on track after reaching the French Open semi-finals following a difficult first half of the season during which he battled shingles, an elbow injury and the flu.

Murray said that he now hopes to get some more time on court over the next few weeks to work on things and aim to improve his game before Wimbledon. Murray said that he made a lot of mistakes and that if he plays in the same way he “certainly won’t win Wimbledon.”
