Brad Lidge was unavailable to close out tonight's 13-11 Phillies victory over the Nationals because he was suffering from discomfort in his knee, according to a team source. As a result, Scott Eyre pitched the eighth inning and Ryan Madson got the save in the ninth.
About a week ago, Lidge underwent an MRI on the knee, which was negative, according to the source.
UPDATE: Phils manager Charlie Manuel said the problem was "inflamation" in the right knee. He said the MRI showed "no structural damage," and that Lidge is listed as "day to day."
