So Kluber has a 1.04 Whip which is pretty much identical. If that's the game you want to play then Kluber has more complete games, more shut outs, a lower ERA, more innings pitched, a lower H/9, less HR's, less HBP, more K's, lower FIP(x), and a higher ERA+
To be fair with the exception of strike outs he's only marginally better than Porcello who has shown better control with less BB/9, lower whip and more wins. Looking at it closer, I feel my opinion may have shifted. Porcello definitely closes the gap but it's not like it was a ridiculous statement to put Kluber ahead of Rick...actually if I had to vote for one right now (taking my Sox biases out of the voting) I'd still put Kluber ahead of him. Also, the Guardians are in 1st place with a more commanding lead for what it's worth.
Anyways.....go Sox!!!
