We know that starters are more valuable and harder to come by than relievers. Starters pitch more innings than their bullpen compadres and must face a lineup multiple times. Because of these factors, starters often have a different skillset than relievers.
When evaluating whether a pitcher should be a starter or reliever, I like to look at three major factors, though I acknowledge there are other things to consider. My big three are as follows:
- Raw stuff
- Command
- Health
A pitcher who struggles with any of these three areas can find himself in the bullpen.
