Cmd
Command grade — projected ability to locate pitches where they are intended.
What Cmd means
Distinct from control, which is only about throwing strikes. Command is the tool that decides whether a pitcher with big stuff starts or relieves.
What counts as a good Cmd
Higher is better — roughly 40 is poor, 50 average, 60 good, and 70 or better elite.
