It’s not like Roger Federer has got an easier opponent waiting for him in the Semi Finals – Novak Djokovic, the hottest thing in world tennis, but beating Jo-Wilfried Tsonga in straight sets, avenging that Wimbledon defeat and and coming out firing after another rain delay has got to have Federer pleased with the way he’s playing right now. In my opinion, the best performer so far in the US Open.
