One of my favorite posts every off-season is to try to guess what the 2026 rotations might look like, based on 2025 performance, who’s coming back from injury, who the team may or may not pursue in FA, and how many veteran MLFAs the teams needs to fill out our perennially empty AAA rotation. Here’s that off-season thought piece, which of course takes zero FA acquisitions or trades into account as of this date, and makes some strong assumptions on the health of some arms (as noted as we go).
So, Here’s a quick analysis of where we ended 2025 and where we might start 2026 for our entire system. In each section, i’ve got the “candidates” lined up roughly from most to least-likely to be on that team, and then those that make sense to do so are pushed down to the next level.
Yes, it’s way too early to do this. I can revisit this next Spring with updated information/transactions, then use it in early April 2026 posts when we see who the rotations are, to see how decent a job we did predicting. I’m always up for proving how bad I am at player evaluation 
MLB
In House 40-man Candidates: Gore, Grey, Cavalli, Lord, Alvarez, Irvin, Parker, Ogasawara, Lao, Eder (Herz, Williams)
Thoughts: Gore, assuming he doesn’t get traded, should be next year’s Opening Day starter. I’m assuming Grey is ready to go for opening day; he’ll have the entire off-season to prepare, and I can’t see any reason why he’d be delayed, even though he only got a few rehab starts in 2025. Cavalli gave the team 10 starts at a near-league average ERA+ after a long time away and had peripherals that give some hope (velocity up from 2022, Babip of .327 meaning he was a bit unlucky, etc). So, if we got Grey back to 2023 numbers when he was an All-Star, and if Gore and Cavalli pitched to their capabilities consistently, that’s a nice little 1-2-3 start to your rotation with some upside. At worse case all three are hovering around a 95-98 ERA+ as they did this year, which are all typical 3rd-4th starters. That’s the good news.
Here’s the bad news: Irvin led the league in Earned Runs and Homers allowed, and finished dead last amongst qualified starters in FIP, fWAR, and a couple other categories. Parker would have been right there with him in dead last had he gotten a few more innings. What should you do with a guy who’s the worst starter in the league? Well duh, you should put him in the bullpen. Lord’s splits as a starter were not good: his ERA was 2 full “points” higher than as a reliever, and I think he needs to go back to the pen, as much as I like his ascension story to the majors. Alvarez’s debut couldn’t have gone better, but is he a MLB starter? Nobody seems thinks so; he got almost zero prospect love in his career, and I sense he’ll be a rotation placeholder, morphing into the classical 4-A rubber-armed multi-role lefty for this team for the next few years until he runs out of minor league options, but he held his own and (for now) is probably the 4th or 5th starter in 2026.
I don’t buy Ogasawara as a MLB-capable starter; I sense he’s heading to AAA to prove (or disprove) my theory in 2026. Waiver pickup Lao actually had great AAA numbers this year as a starter and was only up in the MLB bullpen to fill a hole at the end of the season; maybe he competes for the 5th starter job next year. Same with trade acquisition Eder, though his AAA numbers weren’t nearly as good. I don’t sense Herz or Williams will be ready to go for opening day 2026; certainly not Herz, but Williams’ “brace” surgery may get him back quicker. Even if he was 100% healthy, he was abhorrent as a starter in 2025 despite his near all-star performance the first half of 2024, and I sense he should be in the bullpen going forward. So, for now they’re all out of the running.
So, what does that leave us with? Three acceptable starters and a bunch of question marks. How much is this team willing to spend on the open market? A 66-96 team is more than one Starting Pitcher away from competing, so my guess is, another mid-level $10M/year starter, open competition for the 5th starter job, hope for incremental improvements from Gore/Grey/Cavalli, and hope for some help coming up from guys who are in AA or AAA right now.
Prediction for 2026:
- Rotation: Gore, Grey, Cavalli, a Free Agent, Alvarez or a spring training competition for 5th.
- Lord, Irvin, Parker to MLB bullpen
- DL: Herz, Williams
- Ogasawara, Lao in AAA rotation
- Eder in AAA bullpen
AAA
In House Candidates: Lao, Eder, Ogasawara, Solesky, Sampson, Conley, Shuman, Luckham, Cornelio, Bennett
Thoughts: First off, we have four guys likely out the door here as being one year MLFAs (Sampson, Conley) who never earned their way up, and another couple guys (Solesky and Shuman) who I believe are be at the end of their 6year runs with us (both will be 28 this offseason, both had 5+ ERAs in AAA, and both seem like they’ve done all they can done in the game). So, I’m assuming these four are gone for consideration next year, at least as starters. The whole Covid year and what it did to FAs still confuses me, so I may have it wrong here, but even if they’re still under contract, neither merits another year in the rotation based on 2025 performance.
Despite being in the MLB bullpen for most of September, Lao, Eder, and Ogasawara have been primarily starters for their minor league careers and one would think the team would want to see if they can continue. Especially Lao, who had really good AAA starting numbers in Seattle’s system before inexplicably getting waived in September. However, I could also see the argument (especially for Eder) of trying them in the bullpen. I’m not sure Luckham has what it takes to succeed as a starter, so I can see him moving into the Shuman role for next year (LR/SS).
So that leaves Lao, Cornelio, and Ogasawara returning to the AAA rotation for another year, joined by Bennett rising up, and then filled out with a MLFA signing. I can’t really see the team dumping the three vanquished starters (Lord, Parker, Irvin) to AAA. We might see Susana back earlier than expected and he could fit in here relatively soon. But opening day 2026, this makes sense.
The team also still has Lara and Adon, both former starters, and one (Lara) still with some prospect love, who pitched their way out of starter roles and who both had abhorrent numbers in the pen in 2025. Could the team return to them as starters? I don’t think so, even if we need them. We need to see if they can contribute at the MLB level out of the bullpen.
Prediction for 2026:
- Rotation: Lao, Ogasawara, Cornelio, Bennett, veteran MLFA
- MLFA/released: Solesky, Sampson, Conley, Shuman
- To the bullpen: Luckham to bullpen as Long reliever/Spot Starter, Eder to bullpen as lefty specialist.
AA
In House Candidates: Kent, Clemmey, Tolman, Choi, Atencio, Sthele (Susana, Stuart, Sykora hurt)
Thoughts: The Nats late-season promotions of basically the entire season-ending AA rotation was the latest demonstration of their typical pattern of starter handling: they like to get starters’ feet wet in the new level before the new season, so we basically already know what most of the opening day AA rotation will look like. Kent, Clemmey, and Tolman all excelled in High-A this year, earned promotions, and struggled in short AA stints. They make perfect sense to start in AA, though Tolman seems to be more suited at this point as a multi-role reliever, so I’m projecting him to the pen. Atencio sat the entire 2025 season on the AA D/L: He was assigned to Harrisburg on Opening Day, then hit the DL before he could make a start. If he’s ready to go for opening day 2026, then he’s here. He was already planned on being part of the 2025 AA rotation, so I’d imagine he’ll come right back here when healthy. If not, maybe we’re pushing Tolman back into the rotation.
Choi, the 2024 minor league rule5 pickup, was up and back from AAA without holding onto his spot and makes sense to start in AA again. I’d imagine he’d make sense to start in the rotation until Susana is ready to go: if Susana is ready opening day, then we have to make a decision on one of Choi, Sthele, or Atencio.
When Susana is ready to go, you either push Choi to bullpen, demote Atencio, or send Susana straight to AAA. I mean, why not? He had 11 AA starts this year and struck out 70 in 47 innings; what exactly does he have left to prove there? I’m sure AAA could find room (Ogasawara to bullpen, or something).
Prediction for 2026:
- Rotation: Kent, Clemmey, Choi, Sthele, Atencio
- D/L: Susana, Stuart, Sykora
- To the Bullpen: Tolman as LR/SS
High-A
Candidates: Randall, Garcia, Meckley, Swan, Linan, Polanco, Tepper, Tejeda, Sales
Thoughts: Last year it seemed like Low-A was the place where we’d have a traffic jam; 2026 will be High-A. I count 9-10 legitimate candidates for the High-A roster next year. Lets talk about them.
Randall only had 16 low-A starts before getting pushed up to High-A and traded to us, but was also a 2024 3rd rounder from a decent baseball school (San Diego), so I can’t see him going back down; he will be in High-A for sure. Garcia got solid 2024 draft bonus and dominated Low-A before his promotion: he’s guaranteed to be in this rotation again in 2026 based on his “investment.” Meckley is kind of like Garcia but lesser on all counts; less draft bonus, lesser performance; I think he’s a victim of numbers and heads to the bullpen. Swan started this season in LA’s High-A team, finished it in ours, and showed basically the same stuff year long: good arm but wild. I think he repeats High-A but could also get socially promoted if a need arises given. He could also go into the pen and transition to a high K reliever. Linan only gave us one High-A start before hitting the DL: he had the best numbers of the three trade acquisitions for their prior teams and probably will be one of the first to move up. But what was his injury? I’m putting either Linan on the opening-day DL, based on ending 2025 on the DL.
Polanco just turned 24 and just finished a full season making 23 starts for Low-A; he’s moving up, with nothing left to prove in Low-A. He’s gonna either sink or swim in High-A. Tepper spent entire 2025 on the DL and his usage has been all over the road; I’m not sure he’s ready to be a starter, so I’m guessing he goes to the pen. Tejeda suddenly stopped pitching on August 3rd, but was a gun-slinging 6′ 8″ effective starter before that; i’m hoping nothing bad happened, and he slots right into the 2026 rotation. Trade acquisition Sales finished off a great year in Low-A, pitching well for both his old and new teams despite being “just” a 10th rounder; he’s solved Low-A and has to be here.
I could make the argument that Randall is less effective than Swan and those two switch places. Or, you could look at Swan’s K/9 rate and think ‘high end closer’ and put him in the pen.
If Linan is healthy, what happens? He’s a bit young yet for AA and definitely needs more High-A time, so perhaps he pushes Tejeda to the bullpen. Or, perhaps Tejeda is still hurt from whatever injury he sustained on or about August 3rd. But for now, here’s what i’m thinking:
Prediction for 2026:
- Rotation: Randall, Garcia, Polanco, Tejeda, Sales
- D/L: Linan
- To the Bullpen: Meckley, Tepper, Swan
Low-A
Candidates: Sullivan, Romero, Johnson, Agostini, Farias, Feliz plus 2026 college draftees Tonghini, Maddox, Moore, Biven, Huesman, Puk
Thoughts:
Sullivan, the 2023 draftee, missed basically a year and a half, but has more or less dominated Low-A in the 9 cumulative starts he’s made there. He’ll turn 24 in May of next year and really does no good in Low-A, but there’s just too many arms so he starts in Low-A again. He returns. Same with Johnson, who made 8 low-A starts with a 5-something ERA this year as a very old 2025 draft signing. Romero made 14 Low-A starts, missing a month or so of time, with middling results; he’s heading to the bullpen. Agostini missed most of 2025 with injury but is a solid prospect; he should return if healthy.
Two new names moving up from FCL for next year should be Feliz and Farias. Feliz is looking like a solid prospect and is starting to get top-20 prospect love; he had a 2.20 ERA in the FCL this year after posting a 2.96 ERA in the DSL last year. He moves up and is an important young arm for us. Farias wasn’t great in the FCL this year but is already 23 and kind of has to move up; i’m putting him as the 5th starter in 2026 unless the team wants to compete him with one of the 2025 college guys.
All six college 2025 draftees are mentioned in Low-A to begin 2026, but I think all of them will go straight to the bullpen based on their college usage and pro potential. We’ll summarize our 2025 draft day posts here briefly; Tonghini was a setup-guy at Arizona. Maddox was a college SEC starter but a senior sign/5.56 ERA guy. Moore was a bullpen guy his first two years in college and pitched his way out of ODU’s bullpen before getting drafted, but wasn’t great as a starter. Biven was a swingman at Louisville. Huesman barely pitched at all at Vanderbilt, and Puk was a multi-inning Opener for FIU. None of our drafted college arms really project to be useful rotation pieces. The best option to start would be either Maddox or Moore if they need an arm.
Prediction for 2026:
- Rotation: Sullivan, Johnson, Agostini, Feliz, Farias
- D/L:
- To the Bullpen: Romero, Tonghini, Maddox, Moore, Biven, Huesman, Puk
FCL
Candidates: Harmon, Sime, Lunar, Portorreal, Reyes, Carela, Gimenez
Thoughts: Harmon and Sime are our two big bonus prep arms from the 2025 draft: I suppose its possible they start in Low-A in 2026, but that typically hasn’t been the MO of this team with its high school draftees. I’m guessing they do XST, ease into pitching, start in FCL and then maybe move up to Low-A later in the summer if they blow away their fellow teenagers in the complex league.
Lunar and Portorreal repeat FCL after middling 2025 results. Both are still relatively young as a 24IFA and 23IFA respectively. I’m guessing they make way for the three more promising arms coming up from the DSL and move to the bullen.
Moving up from the DSL are the three best starter prospects from the island this year in Reyes, Carela, and Gimenez. All three pitched solidly and it will be interesting to see how they fare. Reyes is a bit older as a 23IFA, while the other two didn’t start the year in the DSL rotation but pitched their way there as 24IFAs. None of these three were big money IFA signings, so they’ll be on a short leash.
One thing to keep in mind: the team loves using the FCL as a rehab weigh-station, so it’s entirely possible the “rotation” ends up being 4 guys and a rotation rehab start; they did this for a while this year.
Prediction for 2026:
- Rotation: Harmon, Sime, Reyes, Carela, Gimenez
- D/L:
- To the Bullpen: Portorreal, Lunar
DSL
Candidates: Torrellas, De La Cruz, Robles, Mejia, Carrasco, Reynoso, plus 26IFA class
Thoughts: Torrellas, De La Cruz, and Robles finished 2025 in the rotation. Mejia and Carrasco were in the rotation to start 2025 but pitched their way out; they could get another shot but seem more likely to head to the pen. Reynoso is an unknown, having pitched in 2024 then missed all of 2025; i’d guess he’s bullpen bound.
The team signed 6 arms last January; not one of them featured in the 2025 rotation. Perhaps we’ll see some of them step up, but it doesn’t seem likely. Not one 25IFA arm had decent numbers this season. However, they also didn’t feature a single 24IFA signing in the 2024 rotation, preferring to bring them onboard a bit more slowly. The Nats havn’t really focused big bonus dollars on arms lately; just one non-trivial bonus amount in the last several drafts (Jose Feliz for $120k in 2023, then several guys in the 2021 class who are already gone), so it’s little surprise they struggle to find competent starters in the DSL.
Prediction for 2026:
- Rotation: Torrellas, De La Cruz, Robles, plus two 25IFA or 26IFAs.
- D/L:
- To the Bullpen: Mejia, Carrasco, Reynoso
Ok, so that’s what we’re looking at. This may change as we do MLFA releases and signings this coming off-season, or if we add/remove players via trade.
I hope I didn’t miss anyone, but let me know if i’m missing someone obvious and/or if you think i’m crazy.
