Revisiting the Trevor Rogers Trade. Oof.

Nick Turchiaro-USA TODAY Sports

Usually, with a baseball trade, you want to avoid rushing to judgment. Like, did the Rays get fleeced when they traded David Price to Detroit in 2014, considering that the third piece they got in that deal, Willy Adames, was a starter for three years in Tampa Bay, then got traded again, and is still under team control in Milwaukee? Always in motion, said the great philosopher, is the future.

Usually.

Sometimes you need about three weeks to find out if a trade worked out for your team. So say the Orioles, who on Thursday demoted their big deadline acquisition, left-hander Trevor Rogers, to the minor leagues. The 2021 NL Rookie of the Year runner-up made four starts for Baltimore, totaling 19 innings in which he allowed 16 runs, as well as an opponent batting line of .338/.404/.514. For a presumptive playoff starter, it’s not ideal.

Philosophically, I get what the Orioles were trying to do.

As a side effect of being the laughingstock of baseball for most of the late 2010s, Baltimore amassed a collection of prospects unmatched in the entire league. Some of those prospects turned into Gunnar Henderson, Adley Rutschman, Jackson Holliday, Grayson Rodriguez… the kind of core that could produce multiple MVPs if everything goes right, and form the foundation of a regular World Series contender.

It also produced a lot of prospects who fell into the 11 to 30 range on the organizational ranking: Future big leaguers, in many cases, but with future value grades of about 40, rather than the 55s and 60s you want to build your team around. At this deadline, the Orioles tried to cash in on players from this tier of their prospect list, as well as players who had been on this tier of the prospect list three or four seasons ago and have just become 40-grade big leaguers, full stop. Being limited to a 26-man active roster, there simply wasn’t room for all of them.

After a series of challenge trades and back-of-roster swaps, the Orioles’ liquidation sale returned Austin Slater, Eloy Jiménez, Seranthony Domínguez, Gregory Soto, Zach Eflin, and, well, Rogers.

It’s not quite the coup for Corbin Burnes that Mike Elias and his merry men pulled off over the winter, but it wasn’t too long ago that Rogers was one of the best young pitchers in baseball.

In 2021, he made 25 starts, struck out 28.5% of opponents with unusual velocity from a left-handed starter. And it didn’t seem fluky at the time; he held opponents to a .214 batting average on a .301 BABIP, and his 2.64 ERA came with a 2.55 FIP.

But he had back spasms and a lat strain in 2022, missed almost all of 2023 with a biceps strain, and in between just wasn’t all that good. By the time the Marlins cut him loose, Rogers’ ERA had ballooned to 4.53 — his best mark since his rookie season — and his strikeout rate had floated all the way down to 18.0%. At the time of the trade, he had the fifth-worst K-BB% among starters with at least 100 innings pitched.

And yet!

I get it, man. I was so in the tank for Rogers in 2021, and because my ability to process the passage of time has gone completely to pieces over… I actually can’t tell you when it happened, for obvious reasons. But 2021 doesn’t seem that long ago, and if Rogers was good then, surely he could rebound now. Moreover — and this is in no way meant as a criticism of Elias and his brain trust specifically, because I think every GM is like this on some level — you don’t get to run baseball ops for a major league team unless you have a lot of self-confidence. Maybe you don’t think you’re literally the smartest person in the room all the time, but you have to believe that you can see things that other people can’t, or that you have the ability to hire people who can tell you things other people can’t see.

So Rogers isn’t just a guy who has been good for only one season out of five in his career, he’s a potential find. Why give up a king’s ransom for Garrett Crochet when you can just build a Crochet on the cheap? A confident GM will look at a pitcher like this and say the most dangerous phrase in the English language: “I can fix him.”

But what needed to be fixed? Here are Rogers’ percentile rankings in various statistics, both in that breakout 2021 season and across 2024. (The 2024 numbers include his Orioles stint, which comprises just 15% of his total batters faced this season.)

Trevor Rogers, Behind the Numbers
Year Fastball Velo Chase% Whiff% K% BB% xBA
2021 68th 67th 81st 81st 47th 70th
2024 16th 37th 15th 12th 25th 10th

In 2021, he basically did everything well. Insofar as he had weaknesses, there were two: First, he walked more batters than would be ideal for a starter. Second, he didn’t induce many groundballs, which isn’t necessarily a bad thing if he could keep the ball in the yard. Which he did, with a HR/9 rate of 0.41.

But since 2021, everything Rogers used to do well has fallen apart. In 2021, he had two knockout pitches: a four-seamer with exceptional arm-side run that produced a .300 opponent wOBA, and a sinking changeup that produced a .213 opponent wOBA. Three years later, he’s lost more than two and a half miles an hour off his fastball, and supplemented it with a sinker that opponents are slugging .492 against and whiffing on just 10% of the time. That’s done no favors to his changeup, which has actually increased in average velocity.

So there’s stuff to fix. I might start with getting rid of the sinker, the purpose of which is not clear to me. Maybe tinker with his changeup to shed some velocity and bring that 6 mph gap up closer to 10, like it was in 2021. The Orioles had options, but apparently didn’t get around to any of them.

Well, that’s not entirely fair. Rogers did throw his secondary pitches in the zone a lot more, enough that even over four starts it looks like a deliberate choice. How did that go? Well, with Miami, Rogers’ opponents had an xwOBA of .298 and a whiff rate of 27.6% against his slider. In four starts with Baltimore, those numbers were .427 and 19.4%.

I concede that it’s not always possible to fix a pitcher overnight, but the overhaul that will restore Rogers to his previous glory is yet to be seen. If it’s coming at all.

Which leaves the Orioles in a bit of an awkward position. This is one of the best lineups in baseball, as it was in 2023, when that offensive élan went to waste, as Kyle Bradish and Grayson Rodriguez struggled in their postseason debuts, leaving the Orioles with no choice but to give Dean Kremer the ball in an elimination game. That went about how you’d expect.

That’s why I was so excited about the Burnes trade: It gave the Orioles not just a bona fide ace, but with Bradish and Rodriguez one year older and John Means on the mend, this rotation suddenly had the depth to go best-of-seven with anyone.

Well, Bradish and Means both need Tommy John surgery. The only good thing to say about Rogers’ Orioles tenure is that if he takes the long way to Norfolk down US Highway 13, he can see all the best underwater highway tunnels on the East Coast in one afternoon. More than that, Rodriguez and Eflin are both currently on the IL as well. Eflin’s shoulder injury seems to be relatively minor, though Rodriguez seems to be in a cross-your-fingers situation regarding a return before the end of the season.

All of that leaves the Orioles in the likely position of starting Kremer in an elimination game again.

I guess it’s too early to write off this trade definitively, since the Orioles still have two more seasons of team control on Rogers, past this one. And who knows if Connor Norby and Kyle Stowers, the two young players they sent to Miami, will ever amount to anything anyway?

But insofar as the purpose was to reinforce the Orioles’ rotation for this pennant race, even as nothing more than a depth option, this trade’s been a failure. I absolutely understand why they made this move, but things have gone about as far south as is possible in just three weeks.

Yeah, no one saw this coming – trading for a guy with one good season, an injury history, and a fastball down to 91 MPH. Who knew?

How about the Lane Thomas deal?
The way things are going they would have gotten better production from the guys he was supposed to displace.

The two additional years of team control are key. It seems pretty obvious he needs more work than someone just telling him to change his pitch mix. They very well could have better results with a full spring training, or even if he has to start the season in AAA. A couple months or more of working on improvements is a lot more likely to produce results than trying to fix someone in the middle of a pennant race.

Teams have become so conservative. Nobody wants to trade prospects. Nobody wants to trade stars. This is, in my opinion, mostly the legacy of the expanded playoffs. It’s created a league of mediocrity. Just make the playoffs and anything can happen. So, the Orioles as a top team in baseball needing an ace and a closer with one of the top systems in baseball, so full that they can’t find ABs for Kjerstad or Mayo, went out and got Eflin, Trevor Rogers, and Seranthony Dominguez. This is the new standard in baseball and it’s depressing. Get to 88-92 wins and roll the dice.

Zach Eflin had been pretty good this season and last season – 2.5 fWAR in 135 IP this season and 4.9 fWAR last season. Not an ace (especially if you go by bWAR where he grades out worse), but a good pitcher to add.

Yes and Jazz Chisholm is a real person. So is Randy Arozarena. Padres did give up prospects for relievers. And then there’s Juan Soto but that’s a different kettle of wax.

That 88-92 thing doesn’t explain the White Sox. Or A’s.

The White Sox didn’t trade anyone who disproves this theory.
And they famously made the big “splash” of signing Benintendi in the middle of a supposed window of contention, because they were shooting for 90ish wins and a playoff berth.

Do you think the A’s are ever shooting for a 100 win team?

White Sox traded Fedde to the Cardinals, who were an aspiring 88-92 win team at the time.

The Os are an aspiring 88-92 win team.

Of course, in June they were an aspiring 100+win team, but I digress.

But aiming for, say, 54%, produces the Seattle Mariners, and not the Phillies. You need stars in the rotation and in the lineup; now that BAL has had time to figure out who their guys are, I expect a lot of movement from them in the offseason

It takes two to tango. Everyone second-guesses Elias, but the ask on Skubal may have been Holliday or bust. Crochet simply doesn’t get the Os the innings they need this year, despite what may have been a 55+50+X price tag and the expensive extension demand.

Elias absolutely should play a pile of chips on his current hand. But if everyone else folds, your only return is someone’s ante of…Trevor Rogers.

Is this a criticism of Elias or Harris? If the Tigers really wanted to maximize Skubal’s value they could have probably made some sort of deal with Baltimore or San Diego.

For that matter if DiPoto hadn’t turned into Pat Gillick he could have gotten more than Arozarena and Victor Robles.

Not criticism of either, tho I think you’re right on what Harris *should* have done. Still, not hard to see why he might think anything less than a 60 was not maximizing value.

No objections to the main thrust of the article, but I wouldn’t say Bradish struggled in his postseason debut. You’d obviously like more than 4.2 innings, but 1 BB, 9 Ks, and a 3.86 ERA isn’t a struggle, especially against a lineup that murdered almost everyone that postseason.

While there have been a few success stories among the trade deadline acquisitions, Jason Adam, Jack Flaherty and Frankie Montas stick out, many of the trade deadline pickups have been less than the acquiring teams had hoped for, actually quite a few of them have been total disasters. Up here in New England, Luis Garcia, simply awful, and Lucas Sims, not much better, have tossed high test gasoline on most of the situations they have been used. Along with Rogers, Serathony Dominguez has not helped the Orioles when he gave up 2 walk-off HR’s to the Mets. Justin Turner has provided little help to the Mariners and Erick Fedde has not made a quality start for the Cardinals. The GM’s have to try something but it appears that more teams have weakened themselves than have improved.

Other than Dominguez none of those guys have much of a track record outside of Korea. Expectations shouldn’t have been high. Except Turner who’s ancient.

The Astros acquisition of Kikuchi looks like a very good move but they did have pay a hefty price.

4 starts:
22.1 IP
31Ks
6 ERs
2.42 ERA
3.08 FIP
1.03 WHIP

If he’s able to sustain anything close to this the rest of the year I wouldn’t want to be a Toronto pitching coach this off-season

He did have a 2.94 ERA and a 2.51 FIP in 33.2IP in March/April – so he’s had very good stretches already this season.

True and his stuff has always been praised but the Astros have changed his pitch mix.

He’s now throwing more change ups and sliders while decreasing his curve usage(another gut punch to Michael Baumann). I’ve been calling it the “Blanco approach”.

So if the Astros are able to unlock a better version of Kikuchi that’s a bad look for the Blue Jays regardless of the nice prospect haul

96mncMember since 2020

Reply to  ColonelMustard

My guess is he will. All it took to unlock him was changing his sequencing. His fastball command is still as shaky as it’s always been but by using his change up more the impact of the poor fb command is decreased.

The O’s probably just wanted a controllable LHed SP who they perceived had a high floor and who they could get without giving up their top prospects and this was what that ended up as.

Stowers and Norby would never have gotten an opportunity to play in Baltimore so no harm done.
