The Mariners right hander finished fourth in the voting despite yet another outstanding season.
Tampa Bay Rays left hander David Price won the award, barely nudging out Detroit Tigers ace Justin Verlander, who won the award in 2011. Price finished with 14 first-place votes and 153 points, and Verlander received 13 first-place votes and 149 points. Points are tabulated according to a system that rewards seven points for first place, four for second, three for third, two for fourth and one for fifth.
Hernandez, who didn't receive a vote higher than third-place and received 41 points overall, finished behind Los Angeles Angels right hander Jered Weaver (70 points). The Mariners ace had a fantastic season, going 13-9 with a 3.06 ERA, and throwing a perfect game.
The vote was the closest since 1969, when Mike Cuellar of the Baltimore Orioles and Denny McLain of the Detroit Tigers finished tied in the voting.
