Too early for me to catch the match, but I thought Rafa was recovering from some type of virus, not an injured leg? Or was the injury incurred during this match?
Unfortunate to see Rafa go out like that, but he plays a physically grueling game thus making him more prone to injuries. He should be back to 100% by Roland Garros though.
At this point, I think it'll be a toss up on who wins the tourney, but I have a feeling whoever wins the Federer/Djokovic match should have the edge (even though I would like to see Murray win his 1st GS title).
