Federer ekes out 5-set win

Lots of action going on down at the Australian Open. Roger Federer had a tough match against Tomas Berdych today, and I watched some of it (tape-delayed) this afternoon while at my grandma's place. Federer really looked off during the first couple of sets. He played well enough to take the second set to a tie-break, but he couldn't win it. He finally seemed to get into a groove in the third set and cruised from there. Next up for him is Juan Martin del Potro, and that should be a good match. Djokovic and Roddick are set to play each other in one of the other quarterfinal matches. On the other side of the draw, they're still in the fourth round. Nadal and Murray both play tomorrow, and if they win they'll be in the quarters as well.
