Brad Lidge's first rehab outing appeared to be a successful one at Double-A Reading.

Lidge, who started in Reading's game tonight against Harrisburg, threw one scoreless inning in his first game action since being place on the DL with a right knee sprain on June 9. Lidge gave up a double to the first batter he faced but then retired three in a row, two on strikeouts.

Lidge is expected to throw in at least one more minor league outing to test his knee.

He is eligible to come off the disabled list Tuesday.
