Yes, we are talking about Blake here. He slowed down significantly in the 3rd set. Physical condition translates into the mind. Hopefully he'll learn how to pace himself.

Agreed. Blake needs to master efficient use of energy. He was trying to track down every one of Agassi's attack and it turned out costly for him. He is obviously inexperienced in this sense. Look at how Safin played Agassi in 2004 AO SF one would understand the difference. At Blake's current stage he had little chance to challenge for the title.
