Watch out Roger...

In what could be turning point of the grand slam, Andy Roddick crushed his high-school friend Mardy Fish in quarter finals, 6-2 6-2 6-2. Federer, on the other hand, made his way to the semifinal defeating Tomy Robredo 6-3 7-6 7-5.

It wasn't exactly a comprehensive win. Although Federer managed breaks on Robredo's serve. Robredo keep hitting back and broke back. Federer was quite vulnurable on his own serve, otherwise known for excellent service game. It was the ability of Federer to stretch himself at crucial points that made him winner.

In semis, in my opinion, Roddick can present a challenge to Federer which only Nadal could in recent past. Andy is a big server and with this vulnurable serve of Federer, he can dig a hole to make a grave. On other hand, after some glitches in initial matches, Roddick is cruising along so convincingly that people have started noticing him and identify him as a man who along with Nadal can present a threat to Fedex's throne. Jimmy Connors effect has definitely been showing on him and he showed his intensions by defeating the king in Kooyong Classic final to defend his title. So just keep your fingers crossed, you are going to witness biggest match of Australian Open 2007 on Thursday.
