Games Started
Games a pitcher started.
What it actually is. Games a pitcher took the ball to begin.
What a scout reads off it. This is the line between a starter and a reliever, and almost every rate stat on the mound has to be read differently on either side of it. Relievers post better rates than starters as a rule, because they face a hitter once and can throw their best two pitches at full effort.
