Where do bullpens come from?
I have a theory, which is hardly a unique theory. It states: Minor league relievers are usually irrelevant to major league success. Most key major league relievers are former starters. I'm not sure the extent to which this is true. Obviously there are exceptions, like Troy Percival and Bryan Harvey who pitched in the bullpen from the start of their careers.
On the current team we have:
K-Rod - began as a starter, made 42 minor league starts, switched to the pen and made the big leagues in a year (pretty good finish too).
Shields - Made 68 starts in the minors, did a good deal of relieving too. Did a fine job towards the end of 2003 in the rotation, but the Angels thought he was more valuable in relief.
Oliver - 228 big league starts
Bootcheck - 128 minor league starts
Moseley - 141 minor league games, all starting
Speier - The exception, he's been a reliever his entire time in the majors or minors. He does have 7 minor league starts, but those aren't real starts, they look more like minor league rehab appearances where he just got his 1-2 innings in at the beginning of games.
Then there's Bulger, Thompson, and O'Day. These guys make up the back end of the bullpen.
If anyone who reads this follows another team than the Angels, can you give me the breakdown of your team's key relievers?
