Yes. Murray is not ready to retire and it's hard for him to pull the plug hoping that some miracle might happen and he would fully recover and be back in the swing of things. It's not easy to draw the line and end an illustrious career when your heart is still in it. The heart is willing but the flesh is weak.
He’s already said no to Doubles. But then he said He could be back next year. Who knows? In life the actions are more indicative of a person’s intentions than their words. So it’s more a case of watch this space. If the second op is successful and he were able to return then it is a question of whether Andy is willing to accept playing at the level of Hewitt or Haas after they had their hip surgeries, if that level is possible.
He told his team in mid-December he wanted to target Wimbledon as when he stopped playing. Stopped playing=retirement.
By the time the AO rolled round he was hitting the point where he wasn't even sure he could manage that and the AO might be his last tournament. Last tournament=retirement.
However, if he's thinking he won't be able to hold off from further surgery until Wimbledon then he can have the hip resurfacing operation now and if that heals as well as it possibly can then there's still a chance he could return to playing professionally for some period of time... returning = not retirement.
But the outlook even with hip resurfacing isn't good, and I'll bet hardly anyone will advise him it's worth considering trying to return after it, and there's a strong likelihood that if he takes the surgery then he's already played his last match. Last match = retirement.
Murray clearly doesn't want to retire so whilst there's even a chance he could play again he doesn't want to say "that's it, I'm done as of tournament X" but for the benefit of the world that can't deal with nuance it might be better if he "retired" then "came out of retirement" if the hip resurfacing goes surprisingly well.
