Babe Ruth . Nicknamed `` The Bambino '' and `` The Sultan of Swat '' , he began his MLB career as a stellar left-handed pitcher for the Boston Red Sox , but achieved his greatest fame as a slugging outfielder for the New York Yankees . Ruth is regarded as one of the greatest sports heroes in American culture and is considered by many to be the greatest baseball player of all time . After his retirement as a player , he was denied a managerial job in baseball , most likely due to poor behavior during parts of his playing career . The Atlanta Braves , a current Major League Baseball franchise , originated in Boston , Massachusetts . The World Series is the annual championship series of Major League Baseball ( MLB ) in North America , contested since 1903 between the American League ( AL ) champion team and the National League ( NL ) champion team .
