I’ve created a bit of a dilemma for myself. (Not Jonah Heim related.)
I’m at least reasonably committed to doing the Big Board… but all the questions that I’ve come up with, and that people submitted responses and confidence ratings to, are all scored at the end of the year — except the Braves’ manager one, which is the only one to assign points so far. I’ve wanted to do in-season questions that are resolved and scored sooner, but the 2026 Braves season, as great as it has been, hasn’t lent itself to that for whatever reason. With the Braves dominating, there just hasn’t been much worthwhile, meaty debate on stuff that should or could happen. (I also have a separate dilemma about the best way to score certain things, but… that will be its own series of posts as we get closer to the end of the season and the need for scoring things.)
With that said, I do think Drake Baldwin’s injury and the Braves’ current catching situation lends itself to an in-season question… but, unfortunately, it’s another one that can really only be resolved at the end of the year. Anyway, here goes…
As the Braves waited for Sean Murphy to recover from hip surgery, they signed Jonah Heim to a low-cost ($1.25 million) MLB deal. Heim was an elite defensive catcher from 2021-2023, and the Rangers’ title run coincided with him starting to hit a bit, too, garnering a 4 fWAR season in the process. However, his career fell apart afterwards. Maybe it was the wrist injury he suffered in 2023. Maybe it was something else less overt. But, he went back to not hitting, and more damningly, he went from a cream-of-the-crop defensive catcher to a below-average one. Despite playing for 400+ PAs in both 2024 and 2025, he clocked in below replacement, tallying a combined -0.6 fWAR in the process. His time with the Braves before he was traded was similar despite the small sample of 45 PAs: a .275ish xwOBA, and well below average defensive play. The only reason Heim ended up at +0.1 fWAR in that sample was because he massively outhit his xwOBA in those 45 PAs.
So, that’s Jonah Heim. But, with both Murphy and Baldwin down, the Braves’ other options are… also bad.
Sandy Leon is a 37-year-old veteran of 14 major league seasons who is about as replacement-level as they come. He has a .250ish career xwOBA, and was consistently below replacement from 2019-2025 because he simply can’t hit enough despite the decent defense he sometimes provides. He has a career 0.3 fWAR in 1,752 PAs. He also hasn’t actually provided useful defensive value since 2019, either. It’s not clear why the Braves really wanted Leon rather than some other option, enough to fish him out of the Mexican League when Murphy got hurt again, but here we are.
Chadwick Tromp is 31 years old and is largely a Quad-A catcher. His career xwOBA is even worse than Leon’s (in the .230s). He’s generally gotten positive defensive marks when he’s played enough to accrue them, but he only has 179 career PAs at the big league level. His 0.4 fWAR in that span kinda suggests that he might actually be a serviceable MLB backup catcher, but the problem is that he has a .264 wOBA / .234 xwOBA over those 179 PAs, and if he had a .234 wOBA instead, that positive value probably evaporates. Tromp hasn’t even hit in the minors since 2024. The upside is unclear, if it exists.
The Braves could go outside the organization for temporary help. Unfortunately, there don’t seem to be a lot of options. Guys like Austin Wynns have been on the waiver wire recently, but they’re basically Leon-esque, no hit, some field, veteran options. Heim hasn’t been good in a while but was at least useful once; many of these waiver wire options have rarely gotten MLB exposure and haven’t done much when they have, even if they’ve been around the game for a decade or more.
So, here’s my question to you:
There are two “buckets” of production, for which we’ll use fWAR.
Bucket One is Jonah Heim, since the Braves traded him. (Irrespective of whether he goes anywhere else.) Right now, he has -0.2 fWAR in 20 PAs, which is a bizarrely hilarious -6 fWAR/600 PAs. This bucket consists of that -0.2, plus whatever else Heim does for the rest of the season.
Bucket Two is every non-Baldwin, non-Murphy player the Braves use at catcher this year. This includes Leon, Tromp, and anyone else they use as a stopgap. Leon is currently at -0.1 fWAR (-5.5 fWAR/600, in all of 11 PAs). Tromp had a single in his only PA yesterday, so he’s at 0.1 fWAR in 1 PA. (I’m not pro-rating that, el-oh-el.) This bucket consists of everything Leon, Tromp, and any other guys the Braves acquire to catch do for the team over the course of the season.
Your choices are as follows:
In the below, production means “taking Heim’s rate basis production and applying it over the set of PAs accrued by non-Baldwin, non-Murphy Braves catchers for the rest of the year.” Yes, this is subject to insane variation depending on how much Heim plays. But, there isn’t a better way to do this, I don’t think, because with Heim barely playing for the Athletics, while the Braves are forced to use multiple catchers due to injury, doing a straight-up fWAR basis wouldn’t work.
A: Bucket One (Heim) outproduces Bucket Two (Leon, Tromp, anyone else) by at least 1.0 fWAR. In other words, this is a meaningful difference.
B: Bucket One outproduces Bucket Two, but only by 0.5 to 0.9 fWAR. In other words, yeah, better production, but not really enough to swing anything.
C: Bucket One outproduces Bucket Two by less than 0.5 fWAR, which includes Bucket Two producing more than Bucket One.
Note that due to the quality of player we’re talking about here, “outproduce” can definitely mean less negative.
As usual with these, please assign a confidence score, where 5 is “I am absolutely certain this will occur” and 1 is “I have no idea but feel like participating in this anyway.” So, an answer would be something like A1 (you think it’d be funny if Heim was more productive but you aren’t staking much on it) or C5 (you are certain that the Braves won’t regret shipping Heim off). I kind of imagine that based on the types of people that have participated in these Big Board-soliciting questions, this will be heavily C3 through C5 rather than any As or Bs, but if you truly believe in Heim, here’s your chance to get some Big Board points and gloat later.
