"Definitely the win against Murray in New York was very good, and then against Davydenko, Nadal and Verdasco," Bob Brett, Cilic's venerable coach, said before practice Monday. "He's just become more aggressive. Now he's stronger, fitter, and he's able to sustain it for a longer period of time. Playing these guys more often, it's possible to learn."
Cilic certainly isn't averse to learning, added Brett, who has coached a few other Croats, including the zany Goran Ivanisevic and the intelligent Mario Ancic. Brett has also coached Boris Becker. Cilic and Brett have been together for almost six years.
"What is very good about him is that he's always ready for that something that needs to be changed and added to," Brett said. "He's very receptive and listens to my craziness. He's so committed to being good. He's a great athlete, he wants to be at the top, so he does everything that goes with that. He really has the passion."
