For two sets it looked as if Roger Federer's run at a record 14th Grand Slam title was going to be derailed by Tomas Berdych at the Australian Open.

Berdych , up by 2 sets, had an opportunity  to crush an overhead to basically seal the match, but he shanked it.  Fededer got a little lucky, but didn't waste

the opportunity to get back in the match.  Berdych was crushing groundstrokes and overpowering the Swiss great for most of the first 3 sets.  But Federer

found another gear and was able to battle his way into the quarterfinals. 

"You've got to hang in there, there's no other solution," Federer said. "... Tried to weather the storm. He was hitting the ball so heavy and so hard. He pushed me to the limit."
