If he can move that much backward and forward without cramping he matches up well with Nadal with the strength of his forehand (heaviness) and gets some cheap points on his serve. Dimitrov is also able to hit his backhand high and heavy back off that Nadal forehand with big net clearance which gives him a chance to stay in the point while keeping Nadal from attacking. Fed doesn't play that ball off his own backhand high and heavy enough to neutralize the Nadal forehand.
So basically, Fed is really stubborn?
