Yes. He obviously can't handle it anymore. And the little successes make the situation even more painful. At least for me, as a fan. I see he can still play, but his body can't hold on.
I mean for me, I never lost hope until this year. I can really see his serve, groundies and movement are big problems.
He used to roast guys like this 3 and 2.
I wasn't really ready as a fan to see him go but, I am now. It's time.
