It’s difficult to make a list like this, because from the two spot on down to maybe six or seven, it’s nearly impossible to put one guy over another.
Some pitchers had long careers and good primes, others had shorter careers but amazing primes. Pitchers are ranked on career totals, peak level performance, and length of prime.
Please note that this is a list of the top-10 pitchers in the history of Major League Baseball, and will not include Negro League players. Had I included Negro Leaguers, Satchel Paige would certainly have made my list.
