Basel Tournament and Wawrinka certainly has the big advantage of being a better player but also playing home.
But Kukushkin has shown for a few weeks that he is in huge form and that makes us trust him. He is an indoor player and after Us Open arrived at 3 in Shanghai, winning Roobredo and Anderson, and took a set from Djokovic. In Moscow he won Youzhny and Fognini before losing to the semifinal by the later winner Cilic.
Wawrinka on the other hand after Us Open has not shown anything great losing to the first matches in each tournament.
The Russian has the service to fight the match and if he does not come for tourism, the bet can easily be won.
Also 2 players played for the Davis Cup on the same field before 3 weeks and the score ended 6-7 / 6-4 / 6-4 / 6-4.
If the Russian plays a good set, he can get at least one set, or lead it to TB and the over can come, since his service is very good
