After the 1976 campaign, Steinbrenner added star Oakland outfielder Reggie Jackson—who had spent 1976 with the Baltimore Orioles—to his roster. During spring training of 1977, Jackson alienated his teammates with controversial remarks about the Yankees captain, catcher Thurman Munson. He had bad blood with manager Billy Martin, who had managed the Detroit Tigers when Jackson's Athletics defeated them in the 1972 playoffs. Jackson, Martin, and Steinbrenner repeatedly feuded with each other throughout Jackson's 5-year contract. Martin was hired and fired by Steinbrenner five times over the next 13 years. This conflict, combined with the extremely rowdy Yankees fans of the late 1970s and the bad conditions of the Bronx, led to the Yankees organization and stadium being referred to as the "Bronx Zoo." Despite the turmoil, Jackson hit four home runs in 1977 World Series and earned the Series MVP Award, and the nickname "Mr. October."
