Truly a useless observation but I have to point it out: After Federer won his first set and was walking to his chair, he took the optimum route so that the towel boy from the court corner didn't have to cover a few extra steps, which also means that Federer didn't have to wait a few extra seconds to grab his towel. Interestingly, he won the set without breaking a sweat.

After beating Robin Soderling 6-0,6-3,6-7,7-6 to reach the semifinals of the US Open, Federer said "It was cold in the beginning and I felt at home. After a couple of sets it was even cooler and he must have felt at home."

For those scratching heads - Federer's from Switzerland and Soderling's from Sweden.
