Exactly right Ice... Muller, historically, has been a head hanger and a guy who gets down on himself and just starts BLASTING the ball going for broke. What was amazing beyond his ASTONISHING level of composure - for him - was his point constructions were very, very sharp and effective.
Muller has rarely stayed in that level of a match before, zoning in on an outcome, playing clear headed effective tennis to get the job done, AND DOING SO. Yes, he's won some small events, but, he defied his patterns and career tendencies today, under the proverbial gun! GREAT job!
Sucks for Rafa... the emotion he was radiated out there was almost nuclear! :)
