I'm serious though, he should take a long break after that heartbreaker. Otherwise I don't see him having much success on the grass this year (or even the rest of the year in general).
He'll be alright. QF and pushing the world #1 to his limits is far more than expected from him on clay, by far his worst surface.
He's strong mentally and will not let the defeat crush, but rather take the positives from it. If he can carry that form into the grass season, especially as far as his backhand is concerned, he will be a force to be reckoned with imo.
