It's always quiet among the biggest players in this period - there are no really decent tournaments on and it's a good break before the North American swing in terms of Masters and the USO.
Thanks for the info Joe re: the biggest players in this quiet period.
Not only that but given that Wimbledon comes right after RG, then these players, who should ideally at least make the SFs, are bound to need a break to recover physically and mentally. In fact Andy is perhaps a little unique in that his idea of a holiday is a break of a few days then it's off to the States for rigorous training. I bet your life that Djoko, Nadal and Fed all take proper holidays. Certainly I recall that Henman always took two weeks holiday away from it all immediately after Wimbledon.
Maybe Andy should follow their example, then perhaps he wouldn't be so prone to picking up an injury/virus come the USO - and in that regard perhaps he could ask himself why he came unstuck there both in 2009 and 2010. He takes good care of himself in the run up to the AO, so why not the USO, since these two Slams are the one's he's tipped as being most likely to win?
