McClendon, James, or even Rogers (I assume he won't be called up, due to health concerns) would be every bit as likely to succeed as Kintzler. Losing Kintzler for 10 days is hardly a loss, he's not in the bullpen with healthy Parra and Hawkins anyway. He's great AAA depth mind you, but his ceiling seems very limited. Estrada was very good tonight except for one pitch, and was solid last year before he was overused and lost velocity (He should have said he was unable to work a couple of those times, but always said he could go. It's sad how often guys are injured when trying to "play through" soreness or tightness.), as several relievers were unable to go during that time, though unannounced then. It wasn't until after the season it finally leaked out that Hoffman was not 100%, despite daily denials he was injured at the time. Marco has had a long history of success at AAA, which should translate into at least a serviceable middle reliever.
