During this stretch, Zimmer made several questionable personnel moves. He never got along with left-handed starting pitcher Bill "Spaceman" Lee. The feeling was mutual; Lee nicknamed Zimmer "The Gerbil." Zimmer's outright hatred of Lee ran so deep that he gave the starting assignment in the last game of the "Massacre" to rookie Bobby Sprowl, who had only been called up from Triple-A Pawtucket a few days earlier. Reportedly, Carl Yastrzemski pleaded with Zimmer to start Lee, who, along with Luis Tiant, had dominated the Yankees during their careers. (Lee, for example, won 12 out of 17 decisions against the Yankees in 10 years with Boston.) Sprowl allowed four walks, one hit and one run in the first inning before being pulled and made only three more major-league starts.
