I don't understand much Dutch, but I guess Wassen posted on his website that he is playing with Kas in Auckland and AO and with Haase in Rotterdam?
That would mean that Kas/Kohlschreiber are no TMC contenders. Kas is such a tool, shouldn't a doubles player try to qualify for the TMC?
The gist of Wassen's post on his website is that he and Kas are going to renew their partnership. After all the problems they had, they had a good talk together and want to continue. Their plan is to play as many tournaments as possible early in the season, and I am guessing they will use that as an evaluation.
Anyway, what I got from the entry is that if Kas is going to try to qualify for the TMC, it will be with Wassen.
