John Phalen McInnis (1890-1960) helped five teams to world championships as a stellar first baseman. He broke in with the Athletics in 1909 and soon became part of the elite “$100,000 Infield” with Eddie Collins, Frank Baker and Jack Barry. That team won four AL pennants in five years with three titles before losing to the Miracle Braves in their incredible 1914 sweep. Federal League incursions prompted Connie Mack to break up his famed nine but kept Stuffy through the 1917 season. A great batting eye made McInnis one of the toughest to fan (he struck out a mere 189 times in 7822 career at-bats.) and he compiled a .307 lifetime average. Equally adept afield, Stuffy was a perennial defensive leader at first. In 1921 he made one error in 1651 attempts. His Red Sox record was not exceeded until Kevin Youkilis played 120 error-free games in 2007. McInnis would play for the Indians, Braves, Pirates and Phillies, wrapping his long and distinguished career as player-manager in Philadelphia in 1927.
- His skill at the plate enabled McInnis to accomplish 384 sacrifice hits, the third-best in MLB history
- After his career in the majors, Stuffy coached college squads ending with the Harvard Crimson from 1949-54
