James Robert "Loafer" McAleer was an American center fielder, manager, and stockholder in Major League Baseball who assisted in establishing the American League. He spent most of his 13-season playing career with the Cleveland Spiders, and went on to manage the Cleveland Blues, St. Louis Browns, and Washington Senators. Shortly before his retirement, he became a major shareholder in the Boston Red Sox. His career ended abruptly. During his brief tenure as co-owner of the Red Sox, McAleer quarreled with longtime friend and colleague Ban Johnson, president of the American League. In the wake of this disagreement, he sold off his shares in the Red Sox and broke off his relationship with Major League Baseball.

The St. Louis Browns was a Major League Baseball team that originated in Milwaukee, Wisconsin, as the Milwaukee Brewers. A charter member of the American League (AL), the Brewers moved to St. Louis, Missouri, after the 1901 season, where they played for 52 years as the St. Louis Browns.
