MIAMI -- Dodgers reliever Hong-Chih Kuo's anticipated Friday return from the disabled list is in doubt after he retired only one of five batters in a Class A rehab assignment Tuesday night.
Kuo, disabled two weeks ago with a sore back that led to a relapse of the yips, was pitching on back-to-back nights for the first time this year after having allowed a run in one inning Monday night. In Tuesday night's game, he was charged with two runs on four hits with one strikeout.
Kuo is eligible to be activated Friday, when the Dodgers open a homestand against San Diego. With closer Jonathan Broxton struggling and Vicente Padilla having made only two appearances since returning from arm surgery, the club was hoping the return of Kuo would give manager Don Mattingly more late-inning options out of the bullpen.
