He looked great in the first set but choked it away from 5-2, 3 DFs when serving for the set (at least it wasn't 4...progress
). Murray was half asleep but his defense on big points and Grisha's legendary choking gave him the first set. Grisha was mentally hungover for the second set, hence the scoreline.
Murray was going wide or long when he tried to go for the lines, even in the second set. Not a good sign going forward.
