Four seeds go in Cincinnati 1st round

A whole lot of matches on the Monday in Cincinnati presented us with some surprises as well as a few enthralling clashes.

Four seeds left the building.

Rafa Nadal withdrew late, not through injury - only because he felt like it, denying fans the chance to watch him - a selfish act just like Federer dropping out of Toronto at the last minute.  These are meant to be the leaders in the sport, and they are treating their adoring fans with contempt.
