The Kazakhs keep on being greatly prepared at home despite Kukushkin's injury. Players like Korolev and Golubev who have done nothing for months play two great matches to win their ruber on a surface which is rather better for their opponents.
Indeed :-) Golubev was particularly amusing a couple of years ago. Had made the KL final, then lost a crapload of matches. Suddenly out of nowhere murders Berdych in Davis Cup.
Light at the end of the tunnel? Break the pattern? Some motivation for the rest of the season?
Nope. He did get a win next match, a virtual walkover against a sick/tanking Mayer, but then went on a Spadea-class streak, losing his next 17 matches in a row.
