It is over.
He just got broken. Can't even deal with wawrinka after such an easy match in the last round.
He needs work. There is no other way.
Too much inactivity and lost focus cost him.
He knew what he was doing. He even said he could drop to dangerous levels in ranking. That is how he put it.
No way in hell should wawrinka be able to win more than 5-6 games against Rafa on clay.
Again people just don't realize how much he has fallen.
He can still win this match. He just has to dig deep summon his inner resources and his relentless will.
Most likely he is out today but there is a small chance for a win.
Whatever his problems are, he'll have to fix it. He's not consistent. He makes too many errors. He's in the stands returning. He's lost his will to win. There doesn't appear to be any physical problems as far as injury, so...
