Twins Daily's Top 20 Minnesota Twins Prospects: #2 Emmanuel Rodriguez

[Matthew Lenz]

We're down to the final two in our countdown of the Minnesota Twins' top 20 prospects for the 2024-25 offseason, as voted on by the Twins Daily community. Today, we'll dive into the profile of a left-handed hitter who has a bright future in the Twins outfield. But which one?

Emmanuel Rodriguez was a member of the 2019 International Free Agency class, signing for $2.5 million that July. Now, entering his age-22 season, he's a consensus top-100 prospect in all of baseball and will likely get an opportunity to make the big-league club in spring training. Given his age and questions surrounding his plate approach, it’s a long shot that he makes the Opening Day roster, but I wouldn’t rule out a debut sometime in 2025.

The left-handed hitting outfielder spent most of his 2024 season with the Double-A Wichita Wind Surge, before getting the call to the Triple-A St. Paul Saints for the final seven games of their season. Across 201 plate appearances, he posted a 1.029 OPS with nine home runs and nine stolen bases. While he posted a concerning strikeout rate of 29.4%, that was counterbalanced by an incredible 24.9% walk rate—a sign that his patience at the plate can be a bit of a double-edged sword. The reason for his lack of plate appearances was mainly a nagging right thumb sprain that required multiple stints on the injured list and ultimately resulted in a clean-up procedure after the season concluded. While he has spent most of his time in center field and could stick there at the highest level, it’s also likely that he ends up in a corner outfield spot, given his arm and power profile.

There's definitely a lot to be excited about with the young prospect, but it comes with caution: we need to see if his approach at the plate will work against the best pitchers on Earth. Despite the high walk percentage, he has a little too much swing-and-miss in his game, as he carried a lowly 66.3% contact rate in 2024, which is about 10 points lower than you’d want to see for the level he was at. Moreover, his 32% swing rate is too selective and results in falling behind in counts, while a chase rate under 8% is largely the reason he’s able to maintain such a high walk rate. Ultimately, Rodriguez will be better served finding more of a balance in his pitch selection for the prospect industry to feel more confident in the likelihood he reaches his ceiling as a middle-of-the-order slugger for the Twins.

Rodriguez does a ton of damage against hard offerings, but struggles to attack breaking balls. That's fairly common amongst young hitters, but it’s another area that gives us pause when we look to project his impact. In fact, this has been part of the reason that current Twins outfielder Trevor Larnach has found it hard to sustain success. Unlike Larnach, Rodriguez doesn’t look to be a platoon bat at this point, as he’s been able to do damage against right-handed and left-handed pitchers alike. While he does have a dip in power against lefties, he was able to slash .303/.465./.545 against southpaws in 2024.

Regardless, Rodriguez is inarguably a name to watch in 2025, as he likely spends the season with the Saints and local fans will get the opportunity to see firsthand whether his approach works. After the right thumb sprain in 2024 and a torn meniscus in 2022, Rodriguez hopes to have a full, healthy season and establish himself as a frontrunner for a call-up, if and when there is an opportunity.

Do you think Rodriguez’s approach can work or does he need to make adjustments to avoid becoming the next Edouard Julien?

I saw him once at AAA. Similar skillset to Julien. Please have him work on breaking ball recognition. This question at the end of the article sums up my thoughts. 

-Do you think Rodriguez’s approach can work or does he need to make adjustments to avoid becoming the next Edouard Julien?

 

 

[Doctor Gast]

Sooner or later he'll have to make that change at the MLB level. IMO sooner is better even if it delays his calling up. Larnach? has adjusted, Wallner? kind of, Julien? no, Emma? IMO he can adjust & still have the power. Looking forward for him to make that final adjustment & make a big splash for the Twins this year.

[TwinsDr2021]

Do you think Rodriguez’s approach can work or does he need to make adjustments to avoid becoming the next Edouard Julien?

Such a ridiculous statement, Julien put up a 130 OPS+ as a rookie and had a bad second year (not the first nor the last player this has and will happen to) and we have no idea if he turns into the player he was as a rookie, second year or somewhere in between.

Larnach, AK, Gordon, and others have never put up a 130+, would it be a disappointment if EROD put a rookie year like Julien and never seen the bigs again, absolutely, but 99% of minor league players will never do that. 

Can we talk about our hopes and dreams with Erod without denigrating Julien?

[Doctor Gast]

Emma & Julien had simular approaches. Julien was ignored while in the MiLB. So he got by, by not having to adjust & had success his rookie season. His sophomore year the league was ready for him & he had a lot of trouble adjusting. Everybody knows Emma, they'll be ready for him when he comes up. So he'll have to make those changes now, that's the name of the game, adjusting. Umpires won't be easy on him.

[DJL44]

Rodriguez plays better defense than Julien so he might still provide value as he makes adjustments at the plate.

[DJL44]

I think 2024 is a perfect year for Rodriguez to bounce between AAA and the major leagues whenever Buxton goes on the injured list.

[LambchoP]

I'm pumped and excited for Emma, but I think we should pump the breaks a bit, especially with an MLB debut this year. He only had a handful of AAA at bats which went poorly. He did well in AA but didn't have even a half season there. He has to play a full year before we know what he's capable of. The near 30 percent strikeout rate is concerning, as is his inability to hit off speed stuff. We have seen guys like Larnach overcome this, it just took a few years. I think Erod will be a great outfielder for us for a lot of years, I just don't think we should force a debut until he's ready.

[stringer bell]

Rodriguez is supposed to be a big-time prospect, the kind you insert and and expect to thrive like Royce Lewis. Can Baldelli resist the urge to strictly platoon him when he arrives with the big club?

I'm not a Rocco hater, but if the Twins are going to bring up their best hitting prospects, I don't think they should be protected to the extreme. The #1 prospect is also a left handed hitter with even a better pedigree than Emma. It would be a shame to have both become platoon options.

Teams aren't preparing for Emma any more than they prepared for Julien. The major league teams have the same amount of data on him as they had on Julien. The data they have is camera/computer generated. Julien wasn't "ignored." Emma isn't getting any extra attention. Kris Bryant was a pretty well known prospect and did just fine as a rookie. Jackson Merrill wasn't "ignored" and did quite well last year. Quite a few people had heard of Corbin Carroll before he won rookie of the year in 2023 and then he struggled in 2024. The league won't "be ready for" Emma any more than they're ready for any other rookie, including Julien. That isn't how it works. They don't have special info on him. They've paid the same amount of attention to him as everyone else. The umps won't treat him any differently than any other rookie. Nobody in the majors cares about Emma. He's just another kid trying to make a career for himself. They see dozens of others just like him every season.

[chpettit19]

If they think he's close I'd like to see him on the opening day roster and let him do his learning on the job. Even when he struggles. Assuming those struggles aren't early-2024 Wallner level struggles. If you don't think he'll be completely overwhelmed, give him the Jackson Chourio/Merrill treatment. Let him struggle early. Give him 2 months of hitting at the bottom of the order and dialing in his approach with the hope that things start to click by June. Then by the second half of the season you have your middle of the order star blossoming and come playoff time you may have your "face of the franchise" type piece you're hoping for.

The Twins are more than willing to let their over-the-hill veterans struggle for months on end with the hope that they can reach their ceiling of "mediocre at best" by the time August or September rolls around. I'd like to see them do it with their high ceiling youngsters instead. Emma is a good place to start.

I don't think there's much for him to learn at AAA. The pitchers can challenge him better than the guys at A+ and AA, but not like the major leaguers. For him to truly lock in his approach and balance out the patience and aggression he's going to need he's going to have to do it against major league pitching. Let him start the process now. Recognizing off-speed isn't Julien's problem, hitting it is. Julien's approach is broken because he can't hit off-speed stuff so he doesn't swing at it. If Emma also can't hit off-speed stuff then his approach doesn't matter. If Emma can hit major league breaking stuff his approach will work itself out. His contact rate is what the question is. Not the approach. Can he make enough contact when he swings? If he does the rest will work itself out.

[tony&rodney]

First thing I thought of was .... wondering how many Twins minor league prospects OPS over 1.000 and play outstanding defense?

I have added comments regarding EmRod for two plus years on TD. My concerns before last season referenced the number of plate appearances where Rodriguez displayed a seeming disinterest, almost always due to the score of the game. This was strictly observational. Last summer Emmanuel displayed his talents on a more consistent basis. Yes, there is patience and swing and miss in his game, If one wants to compare ER to a current Twin, the player would be Matt Wallner. They had similar performances at Wichita, I believe. However, ER and MW are only similar at the plate. I think the comparison to Julien is off the mark. Defensively, the two could not be more different and while Julien can muscle some balls deep for HR and XBH, ER has light tower power, an easy 400 foot bomb. Emmanuel is an outfielder with an excellent glove (read what Eric Longenhagen at Fangraphs says about his defense), a strong accurate arm, and really good wheels on the bases and in the field. The Twins absolutely need some help with defense. While MLB pitchers may force him to make adjustments at the plate, I doubt whether Rodriguez will shrink from the challenge. This is a time when I miss Calvin. Among others, Rod Carew was put into the lineup against the wishes of the manager and others at a time when owners and GM's were usually hands off. EmRod is ready now.

A competent manager would not platoon players who hit well against pitchers throwing from either side. A competent GM would immediately step in if platooning occurred. The Twins are in serious trouble if that were to happen to either of Rodriguez or Jenkins.

I think Kepler might be our best example of what Rocco does if he gets a lefty hitting OF who provides great defense, right? If so, I have hopes that both of our top 2 prospects will get longer looks compared to some of our other young hitters.

Looks like a few more picked up on this (Tony too), but I was going to mention this too.  Why compare a stud OF and a strong runner to an infielder who has never been "okay" with the glove and is pretty slow?  I'm excited about Emmanuel because of all of his tools, not just his hitting.  (Although his hitting does look pretty good, potentially in a Wallner mold for early impact as a rookie.)

Exactly all of this. If the Twins are not going to play a potential difference maker like Emmanuel, maybe they should trade him and let him play in another system. After watching dozens of his plate appearances, my conclusion is that he has nothing left to learn in the minor leagues.

[Fire Dan Gladden]

Who is number 1????

The suspense!!

The drama!!

[jmlease1]

He's a really impressive talent, and while the defense might not hold up in CF for long...he's certainly able to cover it effectively right now. The big key for him is going to be on his ability to make contact consistently enough, especially on off-speed pitches. His patience and good strike zone recognition will help him keep from chasing too many sliders outside the zone, but he's going to have to be able to handle the ones that stay inside it to live up to his potential as a hitter.

the other question for him is health, as it is with so many Twins prospects. I'm not going to hold 7 games in AAA in September against him when he basically hadn't played since May because of the thumb injury (which as noted still required an off-season procedure). but even so, he still put up a .400 OBP. I suspect he'll handle AAA pitching just fine, especially with the electronic strike zone.

I think if he were RH he might be on the opening day roster as a 4th OF who played as much as the starters (resting Buxton, platooning with Larnach & Wallner against LHP, resting Wallner/Larnach, etc). I'm not sure the Twins will be comfortable with 3 LH OF, so he might not come up until someone picks up a knock. They also might want to see him get some reps in against AAA pitchers since he missed so much time last season. I wouldn't complain too much if they go that way, but I'd also be fine with them being more aggressive with him and bringing him up early.

What I don't want to see is anyone else being the next man up in the OF/DH slot in 2025 unless Emma just isn't healthy again. There's no one else this close and this talented with as much potential impact as a hitter in AAA (with all due respect to Payton Eeles).

he a huge talent. He'll have to make some adjustments and not be too passive at the plate. He'll need to show he can make consistent hard contact on more than just fastballs. But he looks more than capable. very exciting player.

I agree it would be a shame to see Jenkins and Emma reduced to a strict platoon option. It's a risk given Baldelli's tendencies. However, not every Twins hitter is subject to strict platooning.  Max Kepler comes to mind as a notable exception. I wold hope Jenkins and Emma have a legit chance to surpass Kepler's level as a hitter based on the totality of Kepler's up and down offense during  his career.

[Danchat]

Please, please stay healthy! I just want to see him play a full season, then see what happens.

I won't denigrate Julian.  I think he's a lock bounce back (115 0PS+) guy.  

[Fatbat]

I generally lack patience when it comes to slow rolling development of prospects when they clearly show signs of being mlb ready. No one is a finished product and young men need to be promoted and play until they fail. The faster they fail, the faster they are forced to adjust and up their skillset. Coddling them doesn’t seem to work. Erod should be on the opening day roster as the starting LF. Let’s get this party started, its inevitable.

[stringer bell]

Don’t want to put too much of a damper on a high prospect, but I remember several posters asserting Lee’s readiness. Rodriguez is younger and doesn’t have even a half season’s worth of PAs above Class A.

Unless he’s absolutely blows the doors off this spring he probably will (and should) go to the minors. I think performance will dictate how soon he’s promoted and I hope he gets it right on his first try in the majors.

He won't get it right. He's going to fail. He's going to need to adjust and figure things it out. No matter how long you keep him in the minors. It's why I want him up from the start (assuming they think he's close). What does he have to learn in AAA? To recognize breaking stuff? He can already do that. To recognize strikes vs balls? He can already do that. To field his position? He can already do that. None of that is to say he's going to come up and be perfect or great or even very good.

Jackson Chourio had a .608 OPS in April last year. Jackson Merrill's was .696. Chourio followed that up with a .542 in May and Merrill had a .656. In June they went .897 and .996. Merrill had a dip in July back to .690, but otherwise neither dropped below .800 again the rest of the season. Finished with overall OPS's of .791 (Chourio) and .826 which were good for OPS+ of 117 and 127. 

Chourio has 24 career AAA PAs while Jackson Merrill has 0. Chourio does have 585 AA PAs, but Merrill has 211. That's not too far off from Emma's 30 AAA PAs and 167 AA PAs. Emma has 1016 PAs in the Twins system. Chourio had 1211 in the minors and Merrill had 881. They're both younger than him. He's going to fail when he gets to the majors. And they should let him. If they think he can be great. If he's just another dude it's different. But if you think he's a cornerstone get him to the majors once he's out of things to learn in the minors and let him take his lumps in the bigs. Let him struggle at the bottom of the order. Maybe they think he has more to learn. I don't know. But if he's ready, or close to it, let him run in the bigs. Even when he falls down. Which he will. Royce did. They all do. Let him OPS .600 for a couple months if you think he can OPS .850+ from then on out.

But I'm not a big Lee guy, and wasn't calling for him to start on the opening day roster last year. Didn't think he was ready. He's never performed like Emma has. He's been carried by his draft stock far more than his performance. So I'm not exactly the poster you were referring to here.

[rdehring]

All indications are that this winter is going to be an interesting one.  I cringe when I think of an outfield with Larnach and Wallner on the corners, especially when Buxton isn't in center. 

Considering most moves the Twins make could be via trades, I wonder if one of Larnach or Wallner be on their way out?  Would sure help their overall defense if only one of that pair is out there come opening day.  Should that happen, the likelihood of ERod making the opening day roster just got better.

[bean5302]

I'm really not bullish on Rodriguez. With poor contact rates despite not chasing balls out of the zone, it suggests his plate approach is similar to Julien's, with a similar big hole in the swing MLB pitchers will be able to exploit. Rodriguez does have more game power than Julien so that insulates him a bit, but his BB rate is even more unsustainable against pitchers who can hit their spots. I'd like to see him get at least 200 PA against AAA pitching to see how he fares in BB/K rates.

Fans of Julien consistently point to his production in 2023 as a baseline for him with the argument 2024 was just a sophomore slump from which he's going to rebound. Often ignored is the expected stats being much lower than actual in 2023.
.263/.381/.459 OPS .839 wRC+ 135
vs. expected
.233/.355/.427 OPS .782 wRC+ 115ish

In 2024, Julien earned his production. Pitchers took full advantage of the hole in Julien's swing by jamming him inside with the infrequent fastballs they did throw, and they fed Julien more breaking pitches he's not as adept with handling. Julien's frustration was obvious, and he grew more aggressive with pitches those inside edge pitches he'd laid off in 2023, but he can't drive them so the swings turned into soft outs and K's. Trevor Larnach was also mentioned above. The comparison is apt here, too. Larnach rarely chased pitches out of the zone, but he also rarely swung at pitches in the zone always looking for that fat fastball to crush. Larnach's contact rates are better than Julien's, though so when Larnach got more aggressive, his K rate dropped and more balls wound up dropping in for hits. Living off the mistake fastball can work in the minors with excellent plate discipline, but one only has to look at Aaron Sabato to see what a fine line that strategy really is. If the batters skills aren't elite or the opposing pitcher knows how to place a pitch or attack a players weakness, waiting for the meatball will end with failure.

It's worth noting that I'm pretty sure both Larnach and Julien have better contact rates than Rodriguez. There's simply no margin for error with Rodriguez. I suspect MLB pitchers will eat him alive until he reworks his swing (and reworking his swing may sap his power) which is why I'd trade him or a package for a solid center fielder with a few years of team control if I could.

That's key for me to get excited about a player.  "He can beat the other team, even on a day when he doesn't get a hit."  Buxton and Correa are benchmarks for this.

Or is he Matt Wallner?

Wallner- AA- a24, 342 PAs, .299/.436/.597/1.033, 21 HRs, 107 SOs, 62 BBs
Rodriguez- AA- a21, 167 PAs, .298/.479/.621/1.100, 8 HRs, 46 SOs, 42 BBs
Julien- AA- a23, 508 PSa, .300/.441/.490/.931. 17 HRs, 125 SOs, 98 BBs

Wallner isn't exactly a contact rate master (38.4% whiff rate is awful) while being a patient hitter (not at the level of Julien or Rodriguez, though). There's no margin for error with him either, but he's really good at making the most of his contact when he does make it. Emma seems to be built in the same mold. Lot's of boom or bust for him that likely comes down to contact quality. His slugging (in a smaller sample) beat even Wallner's in AA at a much younger age while K'ing at a lower rate. It will be very interesting to get batted ball data on him once he gets to the majors and see how he compares to Wallner and the other big guys in the league.
