Baseball Toaster was unplugged on February 4, 2009.
Felix Hernandez made his major-league debut today for the Mariners at the ripe young age of 19. He got hit with the loss but pitched well going five innings and giving up three hits, two runs (just one earned), and two walks whiled striking out four. He was pulled after 81 pitchesthe Indians had said he wanted go more than 85.
As a tribute, I thought it would be interesting to look at other teenage pitchers and how they fared.
Here are all the pitchers from the last 25 years who made it to the majors before turning twenty with their teenage totals:
