Hal Chase (Baseball) 5

For two decades at the beginning of the twentieth century, this man was the Mephistopheles of baseball.

An expert at throwing games, he was so skilled an actor that he managed to make easy outs look like hard chances that just missed. A first baseman, and by contemporary accounts a very good one somewhat similar to Keith Hernandez, Chase was heavily involved with gamblers from very early in his career. Although he was accused several times, and by some of the biggest names in the game (Mathewson, McGraw) he was never convicted and never formally expelled from the game, although he became persona non-grata by 1920.

One of the true blights on baseball.
