A native of Enfield, Illinois, Jamerson was a player whose major league career, statistically speaking, was only slightly different than that of Red Bluhm, Eddie Gaedel, or Moonlight Graham. On August 16, 1924, Jamerson pitched for the Boston Red Sox against the St. Louis Browns at Fenway Park. In one inning of work, he allowed two runs on one hit and three walks for a 18:00 ERA. He did not have a decision. After that, he never appeared in a major league game again.
Jamerson died in Mocksville, North Carolina, at the age of 80.
