It was Mark Eichorn. Saw him pitch for Watsonville High a few times in the late 1970s. Blazing fastball. As a 21-year old starter for the Blue Jays in 1982, he tore his shoulder but good when he debuted in 1982, not even satisfying rookie playing time requirements.

Fast forward four years. Next appearance in the bigs, technically his rookie year, was as a 25-year old, Tyler Rogers-style submarine-motion pitcher, only being able to touch the 70s mph. No longer a starter, he went 14-6 as a setup man, with a 1.72 ERA, 10 saves and a 7.3 WAR, best-ever by a rookie. He threw 157 innings with 166 strikeouts, thanks to his unorthodox delivery.

Here's the story: MLB's Slowest Pitcher Was Completely Unhittable

Today, he's a pitching coach at Aptos high school.
