the trajectory at its greatest distance from a straight line. A curveball will have a larger value of BRK than a fastball. The PFX quantity represents the deflection of the baseball due to the spin and drag forces from the path it would have taken under the influence of gravity alone. For example, a fastball would have a small value for BRK but a large value for the spin displacement PFX because of the rising action of the fastball caused by backspin. Conversely, a curveball or slider will have a significant break measurement, but lower spin displacement.

But even more importantly, we have measures of quantities that we never had before. As a result, we now have new and novel ways to study the art of pitching."

PITCHf/x data is generally consistent across ballparks, but there have been instances of apparent discrepancies in the data gathered at certain ballparks. (For example, a pitcher's fastball speed might be 1–2 mph faster at home than on the road.) PITCHf/x uses algorithms to automatically
