Ground ball fly ball ratio
From Wikipedia, the free encyclopedia
In baseball statistics, ground ball fly ball ratio (denoted by G/F), also known as ground outs per fly outs (denoted by GO/AO), is a measure of:
- how frequently a pitcher gets batters out on ground balls versus fly balls; calculated as: (ground outs) / (fly outs).
- how frequently a batter grounds out versus flies out; calculated as: (number of ground outs) / (number of fly outs).
