HR/FB
Home runs per fly ball — how often fly balls hit off this pitcher leave the yard.
What HR/FB means
Volatile year-to-year; large outliers normalize toward 10-13% league average.
What counts as a good HR/FB
Lower is better — roughly .160 is poor, .130 average, .100 good, and .080 or better elite.
