I have always been in the camp of
"If its not broke don't fix it!"
I truly think that Chapman should stay the closer and then stay with our 5 man rotation. We have some strong arms coming up through the minors and Chapman has been proven to be lethal in the 9th.
But that is just my thoughts on it.
Last I heard was that they were going to ease him into the rotation throughout the month of April (since you really don't need a 5th starter until towards the beginning of May). And then they were going to go from there.
Its the wrong decision in my books, but then again, I don't get paid those big bucks to make those decisions either.
