The debate on how Grand Slams should handle long fifth sets arose again after Ivo Karlovic's 22-20 in-the-fifth win yesterday. Roger Federer weighed in on the topic after his second-round win:
"I like the long set format, you know. I don't know what it is about it. I just find it intriguing. People are watching it now in the locker room. Everybody's watching it. They like to see what's happening.
"The problem with these kind of matches is, like, it destroys your tournament after that usually because you just put so much mental effort into it, either just holding serve in that fifth set 10 times, 20 times, 30 times, 40 times, whatever it is.
"I don't know if you can find a compromise. Maybe 6-All is a bit early to have a breaker. Maybe you can do 12-All. I'm fine with the way it is. If they change it, they change it."
