It is really up to the draw now to see if he can win Slam #22. As for his injury, while it is saddening to see him suffer on the court (and off the court), it is what it is at this point of his career. At 36 years old, his injury can flare up at any single moment I just accepted that within me.
One thing I will say this about Nadal: While he is still unlucky with his injuries throughout his whole career, I won’t wonder what could have happen if he wasn’t injured often in his career. I will just enjoy and cherish his tennis career through the fullest!
I am not gonna be those fan that will say, “If Nadal was not injured a lot, he would’ve won 25 slams or more, blah blah…”
He won 21 slams (and counting…) and other special accolades while dealing chronic injuries. As a fan, I can’t really asked more from him other than just play your best and leave it all out there (which he does anyways, naturally)!
