Horace Owen Eller (July 5, 1894 – July 18, 1961), better known as Hod Eller, was a pitcher in Major League Baseball. Eller started his minor league career in 1913. In 1915, he won 19 games for the Moline Plowboys of the Illinois–Indiana–Iowa League. His performance gained the attention of the Cincinnati Reds, and he was drafted by the team after the 1916 season. He pitched five years for the Reds, going 60–40 with a 2.62 earned run average (108 Adjusted ERA+). After his major league career ended, Eller played in the minors for a few years, last playing for the Indianapolis Indians in 1924.
