Good stuff from Djokovic. Merciless in first set; beginning of second set, Nole rolled out his trademarked early-in-set-following-victorious-set walkabout. Decided to focus again after the first two games and slowly picked up his level over the course of the set.
Golubev was nowhere to be found in the first set, but began serving and striking the ball much better in the second set. Obviously though, Djokovic was too big for him.
Keep rollin, Nole.
