Stuffy McInnis

John Phalen "Stuffy" McInnis (September 19, 1890 – February 16, 1960) was an American first baseman and manager in Major League Baseball. A native of Gloucester, Massachusetts, he acquired his nickname as a youngster in the Boston suburban leagues, where his spectacular play drew shouts of "that's the stuff, kid." He batted and threw right-handed.

McInnis broke into baseball with the Philadelphia Athletics as a shortstop in 1909. Two seasons later, he replaced Harry Davis at first base as a member of the famous $100,000 infield, alongside second baseman Eddie Collins, third baseman Frank Baker, and shortstop Jack Barry. Over a career spanning 1909 to 1927, he played for the Athletics (1909–1917), Boston Red Sox (1918–1921), Cleveland Indians (1922), Boston Braves (1923–1924), Pittsburgh Pirates (1925–1926), and Philadelphia Phillies (1927).

In a 19-season career, McInnis posted a .307 batting average with 20 home runs and 1,063 RBI in 2,128 games. He won the World Series four times as a player, doing so with three different teams.
