Robinson's Hollywood exploits, however, did not sit well with Dodgers co-owner Walter O'Malley, who referred to Robinson as "Rickey's prima donna". In late 1950, Rickey's contract as the Dodgers' team President expired. Weary of constant disagreements with O'Malley, and with no hope of being re-appointed as President of the Dodgers, Rickey cashed out his one-quarter financial interest in the team, leaving O'Malley in full control of the franchise. Rickey shortly thereafter became general manager of the Pittsburgh Pirates. Robinson was disappointed at the turn of events and wrote a sympathetic letter to Rickey, whom he considered a father figure, stating, "Regardless of what happens to me in the future, it all can be placed on what you have done and, believe me, I appreciate it."
