Next season, how will the Diamondback starting pitchers perform? To answer that question, let’s create an equation (you could call it a model).
First, I give credit to a previous work, especially for BABIP and LOB weights, that is shown in a model created in 2015 by Matt Jackson.
Let’s start with assumptions.
- A pitcher’s results are a combination of his skill (which is repeatable) and factors he cannot control.
- FIP is a measure of a pitcher’s skill. Although far from perfect, in general it can predict how well a pitcher will pitch in the future.
