Definition – What is Ground Ball to Fly Ball (GB/FB) Ratio?
GB/FB can be a batting or pitching metric. It helps figure out whether the ball will be hit high or low.
It can be used to assess a batter or a pitcher.
A higher result means that more ground balls are produced (hits are more often low). A lower result means that more fly balls are produced (hits are more often high).
Formula – How to calculate GB/FB
GB/FB = Ground Balls ÷ Fly Balls
If a batter has produced 265 Ground Balls (GB) and 170 Fly Balls (FB), then:
GB/FB = 265 ÷ 170
GB/FB = 1.56
This batter’s GB/FB ratio is 1.56.
