Roger Federer broke Tomas Berdych in style at the Australian Open. Down 5-3 in the first set, the Swiss converted a break point in an exciting rally where he hit a great down the line backhand winner which put the crowd on a very good note. 'I was just frustrated and a bit antsy. I'm happy I got out of that first set. It ended up being key to the match. Tomas was great', Federer said afterwards.
