Another thing I observe is for regularly competing players, 3 sets are never exhausting to them. Strange that junior fitness can't handle 3 sets.
So when Nadal wins a match by defending and retrieving, he's playing low level tennis?
And 3 sets can be very exhausting if the rallies are long and physical. They can also be barely tiring at all if the points go quickly. Juniors often grind more because grinding is often the best strategy.
