You have to believe me: I didn’t know what I was getting into.
I was completely unaware of the narrative surrounding Chris Perez in non-save situations (or is it tie games? Or extra innings? I get confused.).
As the kids say, “I didn’t know that was a thing.”
So when twitter exploded last night after Perez allowed two runs to break a tie game, I wasn’t feeling combative. I was mostly curious. There were so many people suggesting that Perez just couldn’t handle that situation that I wondered how I had missed it. How had Acta missed it? WIth those glasses and everything?
I had to look it up. But how?
Thank goodness Al Gore created a magical series of tubes for just that purpose. In two seconds, I found this link and tweeted it:

Mind you, I wasn’t really making an argument. I was just pointing out that the story so many people seemed to be spinning—that Chris Perez is lights-out in save situations but awful elsewhere—is not particularly identifiable in the actual, recorded facts.
I was then informed, of course, that I was doing it wrong. It wasn’t save situations vs. non-save situations. It was that he couldn’t pitch in tie games.

Again, I was just not seeing enough evidence to convince me of the narrative.
Again, I was doing it wrong.
I got a tweet with the hashtag “#NumbersDontLie” (TRENDING!, you guys) that pointed out that Chris Perez, in extra innings, in 2011, had an 8.59 ERA. QED, as they say.
Perez’s problem, couldn’t I see, is related to innings with double digit vintages, in the Year of Our Lord Two Thousand and Eleven, and only a moron could fail to see that connection. Numbers don’t lie.
Except that when I looked up those truth-telling numbers, the sample size was (wait for it…) SEVEN INNINGS.
I would love to tell you how I feel about seven inning sample sizes in bloody and gory detail, but let me put it this way. In ten minutes last night I picked out twelve different seven inning samples from Mariano Rivera’s career wherein he sustained an ERA over 8.00. That guy must suck hard! And in Missouri ballparks in 2012 he has a 100% chance of tearing his ACL! NUMBERS GONNA TRUTHITUDE!
But even more than the ridiculousness of using such a microscopic sample to make it fit the narrative you already had in your head, why not just ask yourself this: self, do I think that 7 innings of evidence is enough to make me believe I understand the psychology, fears, mental roadblocks, and emotional timbre of a man I’ve never met, whose job I’ve never had, and whose beard I can only envy?
Because that’s what the narrative is getting at, right? Not that Chris Perez is physically incapable of pitching in these spots, but that he’s mentally weak, but ONLY IN PARTICULAR situations, and therefore should not be used in those situations.
This dime store psychology lesson, I should remind you, is based on seven innings.
Look. I don’t care what narratives you believe. I spent most of 2011 convinced that Orlando Cabrera was the second unidentifiable shooter from the Zapruder film. I believe Matt LaPorta will never be able to hit a major league curve ball. I believe that one day, Shelley Duncan will come over to my house for dinner, with a bottle of Wild Turkey in place of the more traditional Chardonnay. We all have our own hobby horses, and I’m not here to turn yours into glue.
But I’m afraid we’re missing the bigger point with regard to Chris Perez. I’ve written about this countless times before, but look at the chart below, and tell me it doesn’t scare the bejeezus out of you.

He doesn’t strike guys out like he used to, because he doesn’t throw as hard as he used to. This is a problem. In 2011 he had the lowest K-rate among AL closers. This season he’s striking out fewer batters than JOSH-FREAKING-TOMLIN, while walking nearly twice as many. Luckily, he’s given up exactly zero home runs so far this season, so his ERA hasn’t ballooned. Unfortunately, that is not remotely sustainable.
There are real conversations to be had about Chris Perez, based on significant trends we can see over the last several years. Intelligent people can disagree on whether these are problems that should be addressed or not (believe it or not, I fall into the “not” category right now). They can debate whether it would’ve been advantageous to trade him last off-season, or if it might be some time soon. They can seriously consider whether it makes sense to have arguably a team’s third best reliever pitching in the highest-leverage situations.
And yes, they can do all that while still telling themselves stories about psychology and 7 inning samples. As Homer would say, I like stories. But it’s important to remember that stories are what we use to fill in the spaces between facts. They’re not facts themselves.
The facts are scary enough by themselves, after all.
Also: Kirk, every time we fight it just diminishes this a little bit.
