Well, to be more precise, Ron did say that Roger has not played with prototypes
this year. It doesn't necessarily mean that Roger hasn't hit with other non-prototype frames this year, such as a BLX 95 or some other Wilson racquets that other Wilson sponsored pros are using, such as the one Dimitrov is using, which is 93 sq. in. and not available to the public. I think Mahut also uses a 93 or 95 Wilson that is not sold to the public.
