In November 1999, Voros McCracken, a paralegal who participated in a Rotisserie league in his spare time, posted to the Usenet group rec.sports.baseball, describing the “pitching evaluation tool” he was kicking around in his head. “I call it ‘Defensive Independent Pitching,’” he wrote, “and what it does is evaluate a pitcher base[d] strictly on the statistics his defense has no ability to affect.” (COURTESY OF VOROS MCCRACKEN)
