Pryor Mynatt McElveen was given the nickname of Humpty. Why? I don't know, but I bet it's a funny story.
McElveen had a short 3 year Major League career with the Brooklyn Superbas from 1909 to 1911. He was a light hitting infielder who primarily played at third base, but also played just about every other position on the field, including catcher. Batting just .209 in his career, he was eventually released by the team early on in the 1911 season. McElveen went on to play 5 more season in the minors before retiring. Later on, he would coach Baseball at his alma mater at Carson-Newman College in Jefferson City, Tennessee.
Overall, his career on the diamond was unremarkable, but he does have one claim to fame. McElveen participated on the tail end of a triple play on April 28, 1910 against the Boston Rustlers. It started with a liner to right field that was caught by Al Burch who immediately threw to first baseman Jake Daubert to double off Fred Beck. Daubert then fired it to McElveen at third base who caught runner Buck Herzog in a rundown play. McElveen to catcher Bergen then to short stop Tony Smith to record the third out.
