Joseph John Hauser (January 21, 1899 – July 11, 1997), nicknamed "Unser Choe", was an American professional baseball player who was a first baseman in the major leagues from 1922 to 1929, with the Philadelphia Athletics and Cleveland Indians.

[1] After being discovered playing semi-pro ball in Waupun, Wisconsin, Hauser was signed to begin with the Providence Grsys of the Eastern League in 1918, and found himself back in his hometown two years later, with the Milwaukee Brewers of the American Association.

If he was having a bad day at the plate and some fans were booing, others would admonish them with, "Das ist unser Choe!"

He had his best major league year statistically in 1924, but a broken leg and slow recovery hampered his career in 1925 and 1926.

He later blamed Oakland Athletics player-coach Ty Cobb for over-analyzing and impairing his hitting style.

He might have hit more, and challenged the league record of 54 (set by Nick Cullop of the Millers in 1930), but he was rested to allow an injury to heal so that he would be healthy for the Junior World Series.
