Elmer Joseph "Doc" Hamann (December 21, 1900-January 11, 1973) was a Major League Baseball player. He only appeared in one game, a 15-5 loss to the Boston Red Sox while pitching for the Cleveland Indians on September 21, 1922. However he holds a dubious record which can never be broken. Since Hamann faced seven hitters and did not record a single out, he retired with a lifetime Earned Run Average of infinity. Hamann entered the game in the ninth inning and the Indians trailing 9-5. He walked two batters, hit one, and then walked another.
