They’re good, but long. I assume you’re just looking for basics (like, what do the X and Z coordinates mean).

First off, all numbers are based on the catcher’s perspective. The X-axis is horizontal, and the Z-axis is vertical. Negative X-axis numbers break in on a right-handed batter, while negative Z-axis numbers fall farther.

An extremely important thing to note is that all these numbers are based on a ball thrown at the same velocity, but only affected by gravity (thus, thrown with no spin, and without any wind effects taken into account — like a knuckleball in a vacuum).

Thus, Feliz’s fastball breaks in on a right-handed batter nine inches, and falls seven fewer inches than a pitch with no spin. You can validate these numbers by comparing them to the angle column.

Any greater experts can feel free to correct me here.
