Fumus, you don't have to because I've done it for you.
The matches I've bolded are what I consider to be the big turning-point matches where people thought that that particular loss marked the beginning of the end of Roddick's career.

The only two players who have really owned Andy are Hewitt and Federer, and right now it's really only Federer (who owns everybody else, too, except for Rafa).
Andy's rivalry with Tommy Haas is unique. Whereas Andy will win-one-lose-one with most other players, with Haas the wins and loses go on for several matches at a time. Right now, it appears that Haas has the upper hand on Andy.
He has lost in back-to-back matches to Haas, Ferrer, Nalbandian, Verdasco, Andreev, and Monfils.
