Starting Pitcher Outside Factors Chart

by
March 16, 2017

In the middle to late rounds of a draft, pitchers seem to blend together. Picking between two similar pitchers can be difficult. To help with these decisions, I have created a simple cheat sheet to determine which pitcher has an easier path to success based on several outside factors like schedule strength and bullpen quality.

The chart is simple. I went through each factor which may influence a pitcher’s prediction in which they have no control over. I collected projections on each metric and then found the z-score for each value. Greater than 0 is good, less than zero is bad. Then for each team, I added up the z-scores for a final overall value.

The cheat chart is not perfect. It’s to be used as a guide. For example, if a pitcher is a heavy groundball pitcher, the user may not want to add the team’s outfield defense and home park home run factor. A different user may have the perfect projection set except for bullpen and defense. They can ignore the rest of the information. Additionally, a user may want to create their own category weightings. Again, this is just a guide.

To start with, here are the categories and the where I got the values.
