The 1975 Major League Baseball season saw Frank Robinson become the first black manager in the Major Leagues. He managed the Cleveland Indians.
At the All-Star Break, there were discussions of Bowie Kuhn's reappointment. Charlie Finley, New York owner George Steinbrenner and Baltimore owner Jerry Hoffberger were part of a group that wanted him gone. Finley was trying to convince the new owner of the Texas Rangers Brad Corbett that MLB needed a more dynamic commissioner. During the vote, Baltimore and New York decided to vote in favor of the commissioner's reappointment. In addition, there were discussions of expansion for 1977, with Seattle and Washington, D.C. as the proposed cities for expansion.
