Harvey Schlemkowitz- He couldn't make it out of t-ball TJ at 9, selling shoes for a living in Debuque Iowa
Wildman Billy Snotpicker- Ruined his shoulder with his now infamous super rolling hook shot pitch...Complete shoulder blow out at 8 1/2 Joined a Jesuit Monastary in shame
Ernie "Whatthehell" Snodgrass- dislocated his thorax in a "trick pitch" situation...10 yrs old...Hides in his uncles closet and worries about aliens.
All you guys listed fellas that made it to the major leagues...many for multiple years and with many awards and large fortunes..I think their mechanics may have been good enough...I'd trade my left ... to be anyone of em.
By worse mechanics what is the delineator? Failure? Injury? A combination? Internet derision? W/L? ERA?
I know the op asks about major league....but it just sticks in my craw, MAJOR LEAGUER....thats tall cotton brother...words like good or bad in relation to any aspect of how they got there is measured against what? how many place marks to the right? .0000000001% or greater get there...Win the lotto, odds are better, before you are a MAJOR LEAGUER and then how many more before you are a pitcher .00000000000000000001% chance of being a MAJOR LEAGUE pitcher? I'd say, like it or not the very "worst" mechanics mentioned are so much better than everyone NOT a MAJOR LEAGUER as to render the op truely unanswerable.
