Harry Elwood "Moose" McCormick (February 28, 1881 – July 9, 1962) was an American professional baseball outfielder. He played all or part of five seasons in Major League Baseball between 1904 and 1913 for the New York Giants, Pittsburgh Pirates, and Philadelphia Phillies. McCormick also served in the United States Army during World War I and as a civilian director of the United States Army Air Forces during World War II. Under manager John McGraw of the Giants, he was one of the first pinch hitters in the game's history and was considered one of the best pinch hitters in the game.

After the season, the Pirates traded McCormick to the Philadelphia Phillies with Kitty Bransfield and Otto Krueger for Del Howard. However, McCormick stopped playing baseball, working as a steel salesman for the next three years. McCormick returned to baseball in 1908. After appearing in eleven games for the Phillies, batting .091, the Phillies sold McCormick to the Giants. McGraw decided to use McCormick as a pinch hitter due to his lack of speed. While rounding third base during a game, Cy Seymour, who was coaching third base, tackled McCormick. When Giants manager John McGraw inquired, Seymour made an excuse about having the sun in his eyes. This led McGraw, now realizing the need for a full-time coach, to
