My top two: Dizzy Dean and Steve Carlton--but I wouldn't argue with a quartet with Koufax and Ryan. Among today's pitchers, the only ones I think come close are Scherzer, Strasburg, Sale, and Price--and all four are young enough to get better.
“My top two: Dizzy Dean and Steve Carlton—”
Koufax, Carlton as the lefties, Gibson, Ryan as righties.As a lifelong Cards fan, cannot believe to this day that they traded Carlton. He was a monster
Walter Johnson, of course, is the greatest pitcher of all time. Here is my top-ten list, not necessarily in order of rank:
Walter Johnson, Lefty Grove, Christy Mathewson, Warren Spahn, Grover Alexander, Steve Carlton, Tom Seaver, Bob Gibson, Sandy Koufax, Greg Maddux.
(I'm leaving Cy Young off because he pitched much of his career pre-1900.)
