It's a sliding scale that depends on how good he is. I want to see good peripherals: BB rates high, K rates manageable, etc. Also, I really wish we hadn't sent Samardzija out for the ninth in his last game. He's gassed early today.
No matter what happens in the fifth, I wouldn't mind that being it for Samardzija. Nine-run games are made for mop-up relievers and saving the starter's arm.
