FanGraphs Weekly Mailbag: October 31, 2026

The end of the World Series is the best time of year for baseball writing, when some of the greatest scribes working tell the story of the championship team’s triumph with a literary flourish worthy of the feat they are covering. These are the stories that made me want to become a baseball writer. They are full of rich characters and anecdotes, revealing details that shape our understanding of what we just watched and allow us to feel the thrill of the action all over again. These words live on in our memory just as vividly as the events they describe, and provide a portal for future generations of fans to know what it was like to experience it all as it unfolded. It’s a tribute to these writers that you can read as many of these stories as you want and still get something new out of each of them. I’ve read a handful of them as of Friday afternoon and will probably read twice as many more before I’ve had my fill, and I wanted to share them with you now before we get to this week’s mailbag.
First, of course, we have our own Michael Baumann’s 3,400-word opus on a championship that’s “worth coveting, and worth singing about,” as well as the toll that such an accomplishment takes. Next, we have stories from two of my former colleagues: Stephanie Apstein captured the emotional significance of this championship for both the Brewers and their fans in her story for the Washington Post, and in his Sports Illustrated cover story, Tom Verducci traced the trajectory of the team through the lens of the baseball from the final out, and in so doing, also penned a moving profile of manager Pat Murphy. Over at The Athletic, Andy McCullough laid out how “the Brewers have built a model franchise in a system the stewards of MLB believe tilts against them,” using the looming lockout to contextualize the club’s achievement. And finally, ESPN’s Jeff Passan chronicled how the Brewers’ metaphorical bus “brought together one endlessly loyal group of believers in the stands with another on the field.”
In this week’s mailbag, we’ll be answering your questions on Aaron Ashby’s dominant performance this postseason, how the Tropicana Field mound tastes — yes, tastes — compared to those in an open-air ballpark, and the mechanics of non-player trades. But first, I’d like to remind you that this mailbag is exclusive to FanGraphs Members. If you aren’t yet a Member and would like to keep reading, you can sign up for a Membership here.

The NBC affiliate in Chicago has a meteorologist named Pete Sack. I wonder if he moonlights as an MLB dirtbag.
Ten minutes after I read this comment I said out loud “oh my god PEAT!” Like dirt, this one has layers, folks.
Oh I remember the pain of 2012 Jose Valverde. The 2013 Tigers bullpen sunk them that year too. “Great starting pitching, terrible bullpen” formula doesn’t work well.
Normally true but the 2019 Nats still won it all as they used some of their starters out of the pen in the playoffs.
As a Tigers fan, I agree. So painful. Worst part was Valverde was all-world in 2011,so he HAD to be their 2012 opening day closer, but he was shaky all year & they needed to upgrade mid-season & didn’t.
IIRC, Phil Coke ended up closing games in 2012 & Joaquin Benoit did in 2013.
I do think those teams were the end of “we have 4 great SP, we’ll just let them all pitch 7-8 innings” every playoff game mindset. Just doesn’t work anymore.
I looked it up and from 2010 to 2013, Valverde lost almost 2 1/2 MPH on his fastball.
I don’t understand the idea that individual WPA can something that we can’t do ourselves when voting for a series MVP. But it can still be fun as a tool for helping us reminisce over games.
WPA is designed to quantify the feeling of excitement in a game. If our criteria is that the MVP should go to the player who generated the most excitement for the winning team then we can do that ourselves just fine. I just saw the World Series, I know what I felt. And that’s only if we define a World Series MVP as the one giving the most excitement, if not MVP is a bad measure.
I do think it can be a lot of fun to use WPA to look at it across eras and series though. At this point I have seen enough World Series games that remembering which players gave me the most excitement is a challenge. Remembering Kirk Gibson and Mariano Rivera is easy enough, but how they stack up to Aaron Ashby is not.
I don’t think WPA is a good way of determining a series MVP. It is going to overweight late inning relievers or one big plate appearance. A hitter who hits three or four HR in the early innings isn’t going to accrue a lot of WPA, but will clearly be a front runner for that award. It also doesn’t take into account defense or other peripherals, which Contreras was clearly given credit for this year.
WPA is the most explicitly “just for fun” statistic we’ve ever created. It’s basically only of use for people who want to reminisce about the good old times or for people who like to gamble in game.
Seems like CS at least should be an obvious exception where the WPA applies to the catcher/runner.
WPA is designed to quantify *a* feeling of excitement…
Certainly not *the* feeling.
I’d make Ashby a starter again though there is big injury risk I think it’s worth a try. I think the Brewers move Megill in the offseason, but not Contreas. Remember they kept Adames a couple years ago going into free agency and collected a pick.
>>It’s customary for teams to allow coaches to leave for promotions with other clubs
Is it customary, or is it a standard contractual clause, e.g. “Signee will be released from contract upon contractual offer for a promotion?”
The way the media frames this type of decision, it certainly seems like it’s not in the contract and gets worked out if/when it ever comes up, eg “team X released bench coach Y so they could become manager with Z.” But it definitely seems like the type of stipulation savvy teams wouldn’t overlook.
I wonder if there are similar clauses when players sign in overseas leagues like Japan or Mexico or an Independent minor league to the effect of “If the MLB comes calling my contract gets voided.”
You’ll also see that teams “gave permission to Team X to talk to coach Y”. The only reason you don’t give that permission in the offseason is if you’re offering coach Y the same job as Team X is offering. You certainly get dibs on promoting your own personnel. It’s an unspoken term, I think, because you’re going to want to do it yourself someday, and also hiring a coach by a team known to stand in the way of such promotions (which usually involve significant increases in compensation) is not a good way to get yourself good coaches.
I love the Mailbag, both the article and the mailbag itself. Delightful.
Fangraphs rocks.
Mailbag, amazing as always.
Randy Winn Stats, Height, Weight, Position, Rookie Status & More | Baseball-Reference.com
Randy Winn’s baseball-reference transaction from October 2002 does mention that he was traded for a manager. So there’s a counter-example.
I spent so much time Googling stuff about official MLB rules about trades that I never even thought to just check if they include the manager in the transaction log. Thanks Jon!
i am told that ‘night soil’ is not a component of the reds’ mound
Please bring home Stl dirt for Thanksgiving .
Should the relief performances at all be adjusted for run environment? The playoffs in generally this year were low scoring.
Or does WPA already factor that in?
The question was about the “best postseason performances ever by a relief pitcher”, not the most valuable ones. Hence the answer is obviously 2013 Koji Uehara. Thank you; I will not be taking questions.
