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.)
No Ryan but you put Maddux on the list? that’s ridiculus. A strikeout record that will never be broken and a no hitter record that will never be broken ranks in the top ten
What about Randy Johnson? Once he learned the craft, from advice from Nolan Ryan, he was pure domination.
