MLB The Show 09

I have been playing MLB 09 a lot recently, with my pitcher account. Just a couple minutes ago i got my guy called up to be a Long Reliever for the Toronto Blue Jays. Yay. I also have just recently learned the different, specific kinds of pitchers. There is (obviously) a starter, then a long reliever, a middle reliever, a setup man, and last of all, a closer. Until now i only knew starter, reliever, and closer, i didnt know about a long reliever, a middle reliever, and a setup man.
