The Bullpen Changed Since January

Inspiration.

In January, I wrote about bullpen pitchers. Sometimes, when I thought about the bullpen, I stopped because changes were happening.

Now, I wonder how often do ‘new’ pitchers make appearances from the bullpen? In the first 45 games, the answer was 46%. That surprised me!

Details follow:

In January, I compared bullpen pitchers. Pitchers in the minors who escaped my attention, and pitchers who were not Diamondbacks (either in the Majors or the minors) are defined as ‘new.’

After January, four bullpen pitchers were acquired: two of them who were acquired on minors contracts (Shelby Miller and Juan Morillo) are now in the Majors.
