What interpretation, i think the rules are pretty straight forward. He made the quarters, it was the same situation as Schuettler's.
no, because Wimbledon was played after the inscription to the Olympics
if I understood well, the criteria were reached according to some people because Mayer was part of the top-24 ... if you excluded the players who ranked above him but who couldn't take part in the Olympics (Fish's choice, Dolgo's impossibility, Lopez and Granollers after the top-4 from Spain)
Haven't checked their points to defend in the next few months but, if Potito manages to bounce back later with Pippo and Lorenzi holding on, there's at least a chance for a year end ranking including 7 Italian players in the top 100!
