PRIG (Pitchers Rate Index Grades) is actually a family of pitching statistics. The PRIG stats form a "report card" of park adjusted/league relative A+ through F grades for the rate statistics that characterize pitching performance.

The PRIG family includes SPRIG (starting pitchers), RPRIG (relief pitchers), TPRIG (team pitching), TSPRIG(team starting pitching), and TRPRIG (team relief pitching).
