The Seattle Mariners have two All-Stars this year, and they are both starting pitchers. Hisashi Iwakuma and Felix Hernandez have been an impressive one-two punch at the top of the M’s rotation. These two guys have undoubtedly been two incredible bright spots on-what is perceived to be-one of the weakest pitching staffs in the last few seasons under Jack Z.

These two gentlemen are two of the best pitchers in the American League, and some people are beginning to wonder which pitcher is better; is it Felix Hernandez, or Hisashi Iwakuma?

To determine this, we are going to examine their K/BB, HR/9, FIP, xFIP, and WAR for the 2013 season. So let’s get to it;

It isn’t even really close, Felix Hernandez is by far and away the better pitcher of the two Mariners headed to the All-Star Game. Hernandez’s vastly superior FIP, xFIP, and HR/9 show that he is better at preventing the other team from scoring runs; while his higher WAR indicates that he is more valuable to the Mariners than Iwakuma. This is just really another reminder that Felix Hernandez is a badass and all of us Mariner fans should be thankful that he is extremely confident in Jack Z’s rebuilding plan.
