Sorry for Rafa's woes. But I am happy John Isner made it. I don't know how the conditions will be at the Tour Finals this year, but John's serve is dangerous anywhere. I think it helps him in return games to have a slower and higher bouncing court, so we will see. He was impressive in Miami this year. I will be very happy if John wins it all - and becomes the first USA winner since Pete Sampras in 1999.
