Miller corroborated Helyar's account in his 1991 memoir, "A Whole Different Ballgame". Miller explained that while Messersmith was the primary test case, as he was still in the prime of his career in 1975, he wanted McNally to add his name to the grievance because he was under the assumption that Dodgers owner Walter O'Malley would end up signing Messersmith to a contract before the grievance could be decided under binding arbitration. McNally, who had been a Major League Baseball Players Association (MLBPA) player rep during his time with the Orioles, was working as a Ford dealer in Billings, when Miller contacted him about joining the Messersmith grievance. McNally agreed, which meant that even if the Dodgers signed Messersmith to a contract, the grievance would go forward. As Miller wrote ironically, "McNally had been a starter for fourteen years, but the last act of his career was to serve in arbitration as a reliever."
