World No.5 Andy Roddick secure a place in Quarter Final after Berdych retired

This could be one of the exciting match to watch but No.9 seed Tomas Berdych has to retired due to illness (no idea what illness). I was watching the live telecast and Berdych was just not moving as agile as he was. Ironically, he still managed to forced the first set into a tie break and also got 18 winners and 2 aces in the short 60 min game 6-7 0-2 against Roddick. My personal opinion is Roddick is weak in his ground stroke and rely heavily on his serve to win matches. The world No.5 seed Andy Roddick is still the man who had won 2003 US Open before. His next match will be against Federer or Lopez (still playing when i wrote this post).
