Unexpected sports heroes.

Panamanian kid who came in the league as a starter back in '95. As a starter he completely failed.

Moved into the bullpen in '96 and instantly made the rest of the league look like a bunch of amateurs with a rising fastball in the mid '90's that no one could lay off of.

Took over the closer's job in '97, and with few hiccups, has turned into the best closer in history on essentially one pitch.
