Free agency was introduced more fully from the 1976 offseason; outfielder Reggie Jackson, who had spent one season with the Orioles after being traded by the Athletics, was the most significant player available in that first offseason. Steinbrenner signed Jackson to a five-year, $2.96 million contract, giving the Yankees a key player, but one who had difficulty fitting in with the rest of the team. Martin had opposed Jackson's signing, and many players were angered by comments Jackson made that were critical of Munson. Jackson and Martin nearly came to blows in the Yankees' dugout during one game against the Red Sox, in which Martin removed Jackson for being slow to field a ball. The incident sparked media reports of disputes between Martin and Steinbrenner, and further conflict between Martin and Jackson. The Yankees of the late-1970s, noted for clubhouse conflict and on-field success, were later nicknamed "The Bronx Zoo", after a book of the same name by pitcher Sparky Lyle, and at the time, New York and the baseball world were agog at their antics. The 1977 Yankees won the AL East and defeated the Royals in the 1977 ALCS. Trailing 3–2 in the top of the ninth inning of the decisive fifth game, the Yankees scored three times to gain a berth in the World Series. Against the Dodgers, the Yankees prevailed in six games for their first Series championship since 1962. Jackson hit a record five home runs in the Series, including three in Game 6 on consecutive pitches, against three different Dodgers pitchers. Jackson gained his own candy bar and the nickname "Mr. October".
