Will Andy Murray play at Wimbledon?
If Murray pulls out of his singles first-round match against Czech Republic’s Machac, he could still delight fans with one last Wimbledon appearance alongside his brother Jamie in doubles.
The Scots have been handed a wildcard to play together and Murray believes that represents his best chance of one last Wimbledon appearance.
‘I’m going to wait until the last minute to see if I’m going to be able to play and I’ve earned that right to do that,’ said Murray, who ended Britain’s 77-year wait for a men’s Wimbledon singles champion in 2013 and won again in 2016.
‘This is not clear-cut where I am 100% going to be ready to play or there is a 0% chance that I can play. That is the situation. I would say it’s probably more likely that I’m not able to play singles right now.’
The two-time Olympic champion added: ‘Maybe it’s my ego getting in the way but I feel that I deserve the opportunity to give it until the very last moment to make that decision.
‘It’s complicated, and it’s made more complicated because I want to play at Wimbledon one more time. I want to have that opportunity to play the tournament.’
Murray’s first-round opponent Machac, 23, has never progressed further than the third round of a Grand Slam.
