Not necessarily. I don't think it was totally crazy to give it to Gagné. I mean, the guy went 55 for 55 in save opportunities in his Cy Young year in 2003, and he was in the midst of a streak of 84 consecutive saves that started in 2002 and ended in 2004. His peripheral numbers were crazy too.
But I think that kind of flat-out dominance and perfection is what has to be expected from a reliever for them to end up in Cy Young contention. And if it's a close competition between a reliever and the starter for the award, you've got to go with the starter.
