As a kid, I thought this name was hilarious. I imagined him spending his time away from the ballpark doing things like, you know, making ham. I was pretty smart as a kid, what can I say.
Turns out, while checking out his Baseball Reference page, Hammaker led the NL in ERA back in 1983. Sure, he pitched just enough innings to qualify, but still shows how much talent he had before injuries pushed his career off the rails.
