The man they call Mo is deserving, to be sure. And even though a hot September from starters such as Zack Greinke, Justin Verlander, CC Sabathia, Felix Hernandez or Josh Beckett could make any of them the front-runner for the award, none is having the kind of lights-out season that would all but eliminate talk of a reliever winning.
Look, I love me some Mariano Rivera. He is, bar none, my favorite Yankee of the Torre-Girardi era. But 60 or so innings of 1.78 ERA pitching is simply nowhere near as impressive nor valuable as 200+ innings of 2.32 ERA, and that’s before you even get into peripherals. That latter number is from Zack Grienke who, if he played for anyone other than the Royals, would be cruising to 20+ wins right now and we wouldn’t be having this conversation. The Cy Young award is an individual award, and as things currently stand, the only reason to not give it to Zack Greinke is if you look past what he has done as an individual and give him demerits for the performance of his teammates.
Mariano Rivera is the best at what he does, and one day he will find himself in Cooperstown because of it. But what he does is not as important as what a starter does, and that’s the case no matter how much we glorify Mariano Rivera specifically, or the role of the closer in general.
