Brewers Trade Proposal: Joe Ryan or Reid Detmers Could Cost Milwaukee Logan Henderson

The Brewers have emerged as one of baseball's most aggressive contenders, but adding another impact starter could be the move that cements their World Series aspirations. Two intriguing trade possibilities stand out: Joe Ryan and Reid Detmers. Landing either pitcher would likely require Milwaukee to part with one of its top young arms, Logan Henderson, creating a difficult decision that could reshape the club's rotation now and for years to come.

When healthy, Henderson has been undeniably effective on the mound. He's managed a 2.97 FIP alongside a 3.05 ERA in his 38 innings so far this season. The innings are the downside, because while Henderson has flashed that top-of-the-rotation upside, he hasn't been on the field long enough to really tap into that over a longer stretch.

The upside with Henderson is the bulldog mentality, plus a unique changeup and a deceptive fastball. As two-pitch combinations go, that one has been electric so far. While the fastball averages just 93 MPH, the approach angle and induced vertical break from his low release point combine to make it feel as though the pitch is rising when it enters the hitting zone. That's a very difficult feeling to get on top of, and he's been very successful when keeping it at the top of the zone. To back that up, Henderson's high-spin changeup has been a weak-contact, high-swing-and-miss offering that's terrorized hitters. It isn't getting hit hard, and it's a real out pitch with two strikes.

Beyond the fastball and changeup, the rest of Henderson's arsenal remains a work in progress. The shape on his cutter isn't great, especially for his lower arm angle, but it does provide a bridge between his four-seam and changeup. The occasional slurve rates out well from a stuff perspective, but it doesn't blend all that well with his primary pitches and he's struggled to command it at all, giving up some loud contact over the heart of the plate.

With more innings, Henderson could very well improve his feel for the cutter and slurve, but there might be some concerns about getting to those innings. Pat Murphy mentioned that Henderson does see his stuff diminish from 70-80 pitches onward in an outing, and that's not helped by his reliance on his two primary offerings. Compounding that is that, when he gets hit, he gets hit hard. Henderson owns the record of the hardest-hit baseball in history coming against him, and we've seen several times this season some fly balls reaching the upper deck and just barely being foul. When hitters line him up, the contact gets loud, and that perhaps suggests some regression is on the cards.

In some ways, he offers an apt comparison with Drew Rasmussen, who's succeeding with the Tampa Bay Rays over the last two years but faced a myriad of injuries that held him back after the Brewers traded him away for Willy Adames in 2021. Rasmussen has learned to induce weak contact with the best of them, but so far, we can't say the same of Henderson.

Henderson could very well be a No. 2 or No. 3 starter over the next five or six years, if he can stay healthy and further develop his arsenal. There's a big ceiling there as a player who gets swing-and-miss in the strike zone and is comfortable going after hitters. On the other hand, the Brewers can use Henderson to acquire a more reliable arm to cover multiple playoff runs. He's a valuable trade chip because of the results and the two strong pitches, plus the team control remaining. If Milwaukee decides to capitalize on that value, two starting pitchers stand out as particularly compelling targets:

Joe Ryan
Joe Ryan is one of the top 20 starting pitchers in baseball by fWAR since the start of 2024. Like Henderson's, his fastball can get hit hard when he misses his locations, but he's consistently shown the kind of strong command that avoids that issue. Relying on a low arm slot and a great vertical approach angle, his fastball generates a lot of swing-and-miss up in the strike zone, and he has a complete arsenal operating behind it.

Ryan gave up six home runs in his last start. (That's not a typo, but it's also not usually that much of an issue for him.) Despite that, he has a 3.38 ERA and 3.41 FIP this season, and has the ability to dominate teams for 7+ innings. He has a genuine six-pitch mix headlined by the fastball/sweeper combination. His splitter and sinker keep hitters from sitting on the four-seamer too much, while the knuckle-curve adds more depth than his sweeper. He has the seventh-best strikeout-minus-walk percentage (K-BB%) since 2024, so hitters have to beat him. Usually, they don't.

Under control through 2027, Joe Ryan has a chance to help the Brewers in multiple competitive seasons, and multiple playoff races. He's the type of arm that can go against anyone as the second or third starter in a playoff rotation, and his arsenal variety lets him go deeper and perhaps have more coverage if one pitch isn't coming out right on the day. He's also got the benefit of more big-game experience. Think of him as a xross between Henderson and Freddy Peralta, with more of each's strengths and fewer of their weaknesses.

Reid Detmers
While Ryan offers the higher floor, Detmers represents the higher-upside gamble after taking a significant step forward in 2026. Detmers has one of the biggest velocity differentials in baseball between his fastball and curveball, and has broken out in a big way this season after being relegated to a bullpen role in 2025. His breaking balls, by run value, lead all of baseball, and the movement profiles are beautiful. While the velocity has (as usual) dipped since returning to the rotation, Detmers is showcasing a lower arm slot this season, and although it doesn't grade out as well, I think I like the movement profile more from this slot on his fastball.

Detmers is quite effective at finding the upper third of the strike zone, and has managed to mitigate some of the damage that may come if he loses that command into the lower quadrants of the zone, but he's also well-protected by the rest of his arsenal. If a hitter is sitting on the fastball and swinging early, they're going to be very susceptible to his curveball, which tunnels well before breaking late and violently downward. The slider and changeup tunnel even better, as you'd expect for pitches with less break. The slider dips downward more than would be typical for his arm angle, helping him get underneath bats with more regularity.

If you'd like to see for yourself in the graphic below, proMix+ defines how well a pitch follows another in terms of arsenal variety, proMatch+ rates how well they tunnel off one another, and proMax+ combines the two. Detmers's entire arsenal has great separation, and that plays strongly off the back of his fastball if he can establish it.

Detmers is under team control for one more year than Ryan, reaching free agency at the end of 2028. He doesn't have the same track record that Ryan does, but he's taken a real jump in 2026, and with big questions about the Angels player development system, you have to wonder if the H&H Car Wash could find a few further incremental gains.

Ryan is the safer acquisition, thanks to his longer track record and proven durability. Detmers may possess the higher developmental ceiling, particularly if Milwaukee believes it can unlock another level from his arsenal. The decision ultimately comes down to whether the Brewers prioritize certainty or upside, a debate that could also be applied to Henderson's capabilities. It also comes down, of course, to whether the asking price for one turns out to be significantly higher or lower than for the other. It might well be that the strength of the second piece in a deal for either pitcher headlined by Henderson would determine the level of Milwaukee's interest in them.

Trading Henderson would mean surrendering six years of affordable upside for a pitcher who's more playoff-ready today. Whether that gamble is worthwhile depends on how aggressively Milwaukee wants to chase a championship over the next two or three seasons. Henderson has shown he can compete when he's on the field. That doesn't negate some underlying concerns about his arsenal mix, which affects his ability to go deeper into games, or his health. The Brewers could use his recent performance to headline a trade for either Joe Ryan or Reid Detmers. Should they? Let us know your thoughts in the comments below!

I'd like either of these arms added, but not involving a controllable present starter.

We have prospects that have value I'd be willing to part with, a couple on the 40 that really need to go.

Package kind of deal....may or maybe not for arms of this quality.  But arms that could help.

[wallus]

Henderson has too high of a ceiling to trade. We have a couple of controllable starters that we could move instead.

[KCBrewerfan34]

Like the effort by the author but it makes ZERO sense to trade Henderson for another SP. We’re adding not subtracting!!

[MilwaukeeBeers]

I think Joe Ryan's level of pitcher is Logan Henderson's 90th percentile outcome. I am totally fine securing that in exchange as a. Not to mention Logan having issues staying healthy so far in his career. I think I make that deal with control til 2028. 

[Joseph Zarr]

I get the concern about Henderson's lack of innings overall and his IL stints. I really do. It's been a theme since he's been a Brewer. But, man alive, when he's healthy he's an absolute stud. Why would the Brewers even consider moving that with the current state of the Brewers starting staff? Logan Henderson has never given up more than 3 earned runs in a single one of his 13 outings as an MLB player over the past two seasons. He's only allowed 3 earned runs once. Joe Ryan has conceded 3 or more runs in 6 outings in 2026. He just gave up 6 HR in his last outing at Cleveland. He had 10 outings in 2025 with 3 or more runs allowed. Now, don't get me wrong, Joe Ryan is a very good MLB pitcher. I simply personally do not think he's a great MLB pitcher and he's overvalued because he's the best arm on a very average Minnesota Twins team. He's 30 years old to Logan's 24. There's not a lot of worlds I live in where I'd give away Logan's six years of development trajectory to reach Ryan's current age given what Logan has already showed us. Logan obviously doesn't have the innings Ryan has (and has had) BUT, today, Logan leads Ryan in xFIP, FIP, ERA xERA while having over half of Ryan's WAR in just over 1/3rd of Ryan's innings.

I find this interesting because Henderson in his MLB career has a 73 ERA-, 70 FIP-, 70 xFIP-. Joe Ryan is having the best season of his career and has an 82 ERA-, 85 FIP-, 85 xFIP-. Obviously Henderson has durability concerns but I view Henderson's 90th percentile outcome as a much better pitcher than Joey Ryan.

[LouisEly]

I don't think the question is as much about "who is better" as it is "who do the Brewers need more?"

The Brewers, right now, need innings to cover just to get to the playoffs in one piece.  Advantage - Ryan.

But once the Brewers get to the playoffs, they are going to have to beat some teams with big LHH bats (PHI, LAD).  Advantage - Henderson (and Detmers).

It's an interesting choice (if it is in fact a choice they actually have).  Among the three, Detmers might be the player the Brewers need the most.

As it stands Logan doesn't have much feel for spin. He is still essentially a two pitch pitcher with a bridge cutter. I guess what you're saying is true but I just think MLB hitters are gonna catch up to him. The slider has shown signs of life though he hardly throws it as a pronator so this is subject to change.

In Ryan's MLB debut season he was a year older than Henderson is now and had such bad feel for his secondaries that he threw his then 91mph FB almost 70% of the time. He's certainly come a long way since then obviously so him doing that then doesn't matter to who he is now. I just think it offers some perspective because Henderson is so much further along than Ryan was when Ryan was Henderson's age.

I agree Henderson hasn't shown great feel for glove side pitches because he's a very natural pronator though I don't think I'd characterize him as a two pitch pitcher anymore. He's throwing his cutter 21% of the time this year and 31% to RHH.

The biggest issue with Henderson is most definitely durability and if he's traded I'd imagine it's entirely because the Brewers don't view him as a guy who can give you a starer's workload year in and year out. 

[CA John]

With a lockout looming in 27, why would Brewers trade for anything more than a 3-month rental?

I concur with that! Someone also raised a good point about the lockout looming as well. Maybe Ryan isn't the move because it is very possible it just be a half year rental with how far apart both sides are on a new CBA. I don't think that it is likely but it is a risk you need to factor into the cost. You convinced me. I may have had shiny new toy syndrome after a long day of work. 

[BrewersRice]

Being that the Brewers are short on depth at SP, why would the Brewers trade from a SP on their roster, I love both Ryan and Detmers, but this is not realistic. 

[TwinsBrewersWorldSeries]

I’m a no on trading Henderson.

i’d happily include Gasser, Sproat, or Crow in a package with Fischer and Jett to get something good.

No idea why I'm still up, but really enjoying the discourse here, some great points!

I think that's fair, I just at times question some of the results when teams have seen Henderson more. Ryan's definitely been hurt by his last start in those metrics as well, but that doesn't mean the start should be excluded.

I think the more I've researched this after writing the piece, the more Reid Detmers intrigues me. It's a poor pitching development organisation, I adore the arsenal mix, the fastball has more IVB which can help it play better than Ryan's if he does miss down in the zone, and those breaking balls are LEGIT.

I can see how, from that release point/spin efficiency there's a really nice option for a bridge cutter that can take pressure off his fastball too, a cut-ride kind of offering plus he's under control for two and a half years rather than one and a half.

I do think it's an interesting discussion on future performance and longevity

[wallus]

I would have been a lot more excited for Detmers before he had a semi breakout.

[Brewcrew82]

I'm probably more willing than most to sell on Henderson as the dude hasn't come close to pitching even 100 innings in a season professionally.

I would not trade him for Joe Ryan, though. I might consider it for Reid Detmers, if he were the main piece going to LAA. 

[wiguy94]

I do really like Detmers but one question I have with him is how well is he going to hold up this year down the stretch considering he pitched exclusively out of the bullpen last year and only threw 63 innings. He threw 165 innings in 2024 so it's not like he's never been fully stretched out before but specifically for this season is he going to stay effective for a 180 inning workload plus postseason pitching?

Henderson threw 103 innings last year.

You're correct my bad. Just still a consistent and concerning lack of durability.

He's only seen one team two times in his career in Washington. One time last year and one time this year. The start this year was the best start of his career by fangraphs game score going 6 IP, 3 H, 2 ER, 0 BB, 8 SO and Washington has one of the best offenses in MLB this year. 

I'd say if there's anything misleading about his numbers it's that he's largely been a 5 inning guy in his career so he hasn't been asked much to face an order a third time and he has been more HR prone the second time through an order.

[wiguy94]

Yeah the durability is the big question with him not just from an innings perspective but his leash in game is typically shorter in terms of pitch count than other pitchers. Throwing out his start in Kansas City this year where he was the 27th man and more of an opener than a starter, he's had 12 GS, 61.2 IP. That's pretty much 5 IP/start but he's not a five and dive type guy from an efficiency standpoint. He's averaged 15.60 pitches per inning in his career. A guy that efficient should be averaging more like 6 innings a start but the Brewers haven't let him go deep into games.

Matt arnold would put a gun to his head before he traded logan henderson for reid detmers what a dumbass proposal 

[brewmann04]

How many years of control for Logan?
