Brad Lidge (hernia surgery) allowed a run on two hits and a walk over just 1/3 of an inning in his first rehab appearance with High-A Potomac Monday. Lidge was then yanked after reaching his pitch count limit. It's not an ideal showing, obviously, but the Nationals are just worried about whether or not he's healthy. Lidge is expected to make 2-3 more appearances before rejoining the Nats.
