For some reason Australia has chosen to play on grass for their upcoming Davis Cup tie with Switzerland in September. This choice seems foolish considering Roger Federer is pretty much unbeatable on grass!
I can only think this is because they are going to play Tomic and Guccione who both have very large serves and their best surface is grass. However, they need to basically win 2 singles and the doubles, because they will lose 2 singles rubbers to Roger Federer.
There has been no official comment from Tennis Australia on why they select grass over the other surfaces.
The Australia-Switzerland winner will advance to the topflight World Group next year.
