This type of match is why Federer's 65 match winning streak on grass is so impressive. Upsets happen more often on this type of surface than on other surfaces. Of course, the great Nadal is the one that snapped Fed's 65 match winning streak on grass. he also snapped Fed's 56 match winning streak on hard courts as well. Man, if I didn't like Nadal so much, I'd say that he was a major pain in the arse for us Fed fans.
