It depends a lot on who the fifth guy is. You have to consider how long he's going to be sitting out before he pitches again, No. 1, and what benefits you're looking to gain from that.
I think the only other guy I've been associated with who was that dominant was (AL MVP and Cy Young Award winner) Vida Blue in 1971. It's just no contest.
We'd like to see him get on track and feel better about himself. He's an important guy for us. He knows that.
I've seen John pitch. He is a guy that hitters didn't really like facing so we're hoping we can see the same here.
Probably the guy he reminds me of the most is Dave Stewart, and not physically,
It's not really a concern. Izzy's not a guy who really has to have a lot of work. In his case, it can be better for him to throw on the side than to bring him into a (non-save) situation.
It's a real plus when you have a guy who can come into a situation anywhere from the sixth inning on and get a huge out for you. It's even better if he can get a strikeout when you need it. That's a weapon not every team has.
