I am a huge tennis fan, and watched both mens quarter finals.
It was totally gripping, the 6ft 8" South African who beat Roger is certainly a player with a great future.
As for Del Potro v Nadal, I was up out of the chair, give them advice, groaning and cheering, not really minding which won. Quite tearful at the end, when Rafa came round to help Potro up and give him a very big hug.
It promises to be great semis and final. If you like Tennis of course.
