Andy Murray refused to commit to competing at Wimbledon next week despite securing his first victory in almost a year when overcoming Stan Wawrinka at the Nature Valley International.

The former world number one, who returned from hip surgery only last week, convinced in defeating Wawrinka 6-1 6-3 in only one hour and 17 minutes, suggesting he remains capable of being competitive at the All England Club where in July 2017 he secured his previous win.

A Grand Slam would instead present him with the potential challenge of five sets at a time when he has so far lost to Nick Kyrgios over three and overcome his Swiss opponent in two, but having shown signs of progress he said: “My health and my body are my priority right now.

“I will make that decision when I’m ready. If I feel like I’m in good enough shape, I’ll do it. If I don’t, then obviously I won’t play. I’m coming back from a very serious injury which is not easy.

“I’m not putting any pressure on myself to make that decision after one match here or two matches, because I don’t need to. I can decide when I want.

“The match with Nick was two hours 45 minutes, and the slams, you have to be prepared for four hours. That (against Kyrgios) obviously could have gone another couple of sets potentially, and I didn’t feel great the following day.”

In the second round on Wednesday he will face Kyle Edmund.
