The first pinch hitter in Major League history made his historic plate appearance on August 10, 1889 against the Hoosiers in Indianapolis. Mickey Welch of the New York Giants would strike out in this at-bat, but the Giants still went on to win the game, 9-6. Welch went on to become a 300-game winner as a pitcher.

New one on me. Thanks for the info.

You bet! Come to think of it, it’s fascinating that the first pinch hitter was a pitcher, considering that oftentimes now, pinch hitters hit for pitchers.
