Reggie Jackson vs. Billy Martin
The only feud on this list that's provided the fodder for a TV miniseries event, the Jackson vs. Martin rivalry really did set the Bronx aflame. Jackson came to New York in 1977, boisterously declaring himself the ''straw that stirs the drink,'' and immediately clashed with the fiery Yankee skipper. Highly publicized scuffles, including the now-infamous mid-game shouting match in Boston, came to characterize the relationship over the ensuing two seasons. The feud did not slow the Yanks, however, as they went on to defeat the Dodgers in the 1977 World Series.
