Murray played incredibly well last night. I've never seen him play this well before. He was serving lights out, huge first serves with tons of pace and placement, and he didn't hit a single double fault in 5 sets! Truly amazing! He also just wasn't missing at all from the back of the court. He could rally all day long and never miss. That really frustrated Federer who expects his opponents to eventually make some errors during rallies, like hit the ball long, wide, or into the net. Murray wasn't doing any of that. He was just pounding from the baseline all day long without missing. He was just way too good last night. This, combined with Federer's poor serving and movement (perhaps from his bad back, as he had that undershirt on from the very start of the match?), and his poor decision making at times (maybe too much pressure from Murray never missing?), and Federer never really had a chance in this match.
Kudos to Murray for playing almost a perfect match and getting his first win against Federer in a Slam.
