He did precisely the same thing in the 2012 Wimbledon finals against Murray too. In fact, it is how he turned the match around in the second set. He won more points at the net in the second set then the total number of times he approached in the first set win or lose the point, and approached almost twice as much as in the first. For some reason, he does not necessarily stay with it in all future matches, maybe this is where Edberg can really help, by reminding him and insisting on it relentlessly.
I also thought Djokovic played some lose points late in the second set. Federer still had to come up with a spectacular passing shot to avoid going down a decisive break in the second and came up with some great shots early in the third. I think he will recover just fine. I can't necessarily say the same for Berdych who traveled to Hong Kong to play an exhibition match on Monday against Lleyton Hewitt. He is probably traveling right now over the ocean to get to Indian Wells, as well as Hewitt, Li Na and Samantha Stosur who were also in Hong Kong yesterday.
