Debate over who the best pitchers are in MLB takes place year round, but with baseball season in full swing (pun intended), the discussion is at its pinnacle. Every fan of the game has their own criteria for what makes a great pitcher, though for the last several years Justin Verlander, Clayton Kershaw and Felix Hernandez seem to have firmly established themselves as the best in the game.
The most important quality I look for in a pitcher is his results, with quality numbers coming over the course of several seasons taking precedent. Some young pitchers are on the cusp of establishing themselves as top hurlers in the game, but in order to make the top 10 of this list, they have to have made at least 30 starts in the big leagues.
Durability and injury history are absolutely factors considered, and innings pitched, strikeout and walk numbers are the statistics I look most closely at because they are the statistics best controlled by the pitcher.
It's important to note that age was not a factor, since I'm looking at who's the best in the game today and not who will be the best in the future.
I know my criteria is far from the be-all end-all and I look forward to hearing how yours is different.
