Seattle Mariners Organization Discussion
I am now working on the Pittsburgh Pirates. The next team in the line is the Seattle Mariners, then the Florida Marlins, Chicago White Sox, and Milwaukee Brewers to finish out.
Use this thread to discuss the Mariners farm system.

This still isn't an elite system, but it's probably the best it's been in at least 10 years.
They seem to be getting away from the “toolsy” guys that they developed in the past to players with better plate discipline and more refined skillsets (i.e. Ackley, Franklin, Seager, Smoak, Littlewood, etc).
I’m curious how you rank their young positions players past Ackley and Franklin. Guys like Seager, Littlewood, Pimintel, Chavez, Tenbrink, Jones and Liddi make up a decent second wave of players that could make “the leap”.
Also, would you consider ranking Esteilon Peguero, or do you prefer to wait for pro data for teenage international prospects?
Thanks

Also curious about Ramon Morla, Ji-Man Choi and Guillermo Pimentel
I’ve heard Morla destroys bad pitching and is old for his level, but he did rake this year. We’ll see how he makes the jump. I believe BA ranked Pimentel fourth in the system, and he has maybe the highest potential of anyone in the system (but just turned 18). Choi isn’t projected to be a catcher, which hurts his stock significantly. However, his bat was maybe good enough to get him a low ranking in this system.
Curious to see where the relievers (Lueke and Cortes) and the likely relievers (Robles) end up. Brian Moran also made big strides this year and was pitching in High Desert.
I wonder if Tom Wilhelmsen counts. It’s quite possible he’s not much of anything, but he’s been throwing mid-90’s coming off a couple years of layoff and dominated the lower levels this year (albeit at 26). He’ll probably start at AA and maybe move up to AAA by the end of the year. However, he also may end up in the pen.
The Mariners seem very high on Tenbrink and Chavez, in particular. I might like them more than Liddi. Lots of other guys populating the system with a small chance to make an impact: Dennis Raben, Rich Poythress, Carlos Triunfel, Gabriel Noriega, Josh Fields, Anthony Varvaro, Greg Halman (not sure if he even counts anymore…but so toolsy!), Anthony Vasquez, Mike Carp, Blake Beavan, Matt Lawson.

I really liked Tenbrinks swing in the AFL when I saw him there he crushed the ball.
first off: it was a joke dumbs*** and second, who gives a s*** how long you’ve been there? although I will say that being one of the most rec’d posters on a sports blog for the Oakland A’s is pretty impressive to me. it shows me that you’ve attained a level of loserdom that I thought was only imaginable at a Star Trek convention.

I'm nothing close to having a scouting pedigree
Not even in the ballpark, but man, on those video clips of Esteilon Peguero, his swing looks just like Alfonso Soriano’s to me. That would be rad, if he had a similar development . . .

I'm interested to see what you think of Tenbrink/Seager/Mangini.
My guess is that they all top out as role/utility players. I know a lot of guys who follow the system like Tenbrink.

chill
It’s a thread about Mariners prospects, and he’s allowed to express his opinion just as you’re allowed to disagree with said opinion. Even if you think his opinion is wrong, you could have responded to his post in a more constructive fashion than simply telling him to go away.
I’m not saying that Dewey is always in the right with what he says or does. He’s been in the wrong at times and has been informed on occasion to dial it back a bit. If people are unhappy with his behavior for reasons other than “Dewey doesn’t like [insert team or player name here]”, they need to talk to John or I, and they need to do so privately. Other than that, I’d just ask that you (as well as everybody else) refrain from self-policing activities that could get everybody unnecessarily bent out of shape.

I would give him a B+
He will get on base, but will he develop any power or turn his speed into results on the base paths? When you combine those questions with the ones about his glove, I just can’t go higher than a B+.

by King Billy Royal on Jan 3, 2026 3:02 AM EST up reply actions
I'll +1 this
I don’t really believe he’ll play second base for long, especially for a Mariners organization that seems to be putting a strong emphasis on defense. He gets credit for the very aggressive promotion schedule, but I’m still a little disconcerted by the early returns. He’s probably a LF (albeit one who plays the position well), his power is average at best, and even his batting average wasn’t much to talk about. He reminds me a lot of Jeremy Reed, and it’s worth noting that although Reed was expected to hit for a high average with strong plate discipline, his one standout tool (hitting for average) was ultimately negated by his weaknesses. We’ve seen similar things happen with some other top prospects possessing similar offensive profiles (Casey Kotchman, Sean Burroughs, Howie Kendrick to a certain extent, Delmon Young until 2010).
After thinking about it some more, I might actually go B on Ackley. He’s a solid prospect who should be a major league regular somewhere, but I’m not sure I see a lot of above-average potential here and it’s very possible for him to fall on his face.
by mrkupe on Jan 3, 2026 9:40 AM EST up reply actions
Great call on Reed
I have made the possibly Burroughs comparison before as they have similar red flags. You and Dewey may be right on the B call as your arguments have me reevaluating my opinion.

Behind Pineda there is a lack of solid SP.
Robles is pretty darn good if you view him as a SP but has a lot of kinks to work out.
Hensley took a step back.

Agreed
He should sign sometime either late Feb/ early March. I think he could still become a back-of-the-rotation starter but on no where near the time table previously thought.
He may even be better than that estimatation but before speculatuation starts I’d be interested to see where his mechanics and velocity are after so much down time.

Everyone Seems To Hate Ackley Now
I remember back around draft day, a lot of people were really high on Ackley after he literally tore apart college pitching, but as of late I’ve seen more and more people hating on Ackley. Is it him hitting off his front foot, or his lack of consistent power that make people down on him. Can anyone let me know why this is happening and what they see his future (in the MLB) being like.
thanks

define "hating on Ackley"
Do you mean that you’ve seen a lot of people who think he’ll be “just” a solid major league regular as opposed to an All Star caliber player, or that you’ve seen a lot of people who think he’s a fringe major leaguer? The second might be a reflection of somebody not liking him much, but the first would seem quite positive to me.
by mrkupe on Jan 3, 2026 9:43 AM EST up reply actions
Basically
Basically, I’ve just seen expectations for him plummet from draft day to now. Some people say hell be an all star, everyday regular, bench player, etc. There isn’t a consensus on what he’ll turn into, its just that the expectations aren’t nearly as high as they used to be
by emarc on Jan 3, 2026 1:11 PM EST up reply actions
well, that happens
Draft hype is a scary, scary thing. It’s not so much that people dislike Ackley now as it’s just that they liked him more than they should have previously. Very few players project as surefire All Stars, even those drafted very highly.
In college, he had a terrific career but he still showed very average power, an approach that was perhaps a tad too passive, and somewhat questionable defensive projection if you weren’t cool with him as a potentially plus LF. That’s not to say there weren’t good things about him - there were lots of good things about him.
On draft day, nobody had seen him play against pro pitching with a wooden bat (and I’ve heard he had some issues adjusting to both). We now have more statistical data and pro scouts have gotten a chance to see him play. More of the puzzle has been filled in and we have a clearer picture of what we’re looking at.
FWIW, I think we’re looking at a solid regular with a chance to be better than that.
by mrkupe on Jan 3, 2026 1:43 PM EST up reply actions
+1
Hype aside, I think Ackley’s shown himself to be a very capable prospect. He learned a new position last year, eventually hit at both AA and AAA , shows great command of the strike zone, and dominated the pitching poor AFL. That’s not a bad first year. He has shown he can adjust quickly and he wins. I think he project more favorably as a Craig Biggio kind of player than Jeremy Reed, but time will tell.
by goyo70 on Jan 3, 2026 2:56 PM EST up reply actions
sorry, I don't see much Biggio here
Biggio was right-handed and 5’11", so the physical profiles aren’t similar at all. In terms of skills they were similar, but Biggio’s bat was repressed by catching - he didn’t break out with the bat until age 27, his second year at 2B. I don’t think Ackley projects to be anywhere as good as Biggio was in his prime.
Go find out what people were saying about Jeremy Reed a few years back, and look at his minor league numbers. He was eerily similar to what Ackley would be were he an outfielder now. Left-handed, outstanding contact hitter, terrific plate discipline, average at best power, solid speed, both enjoyed great college careers at big programs and were moved quickly.
by mrkupe on Jan 3, 2026 5:39 PM EST up reply actions
Utley then
I do understand and agree with your point about Reed. I see the similarity and freely acknowledge that many hitters fail to develop at the major league level. My point about Biggio was that he was a hitter with a similar makeup coming into his pro career. Versatile, athletic, good makeup, good plate discipline, etc. I’m not trying to belabor the point, but Utley came out of UCLA as a touted 2B (I realize Ackley was a CF/1B out of college) with good hitting skills, a very comparable body size and type, and a comparable attitude toward the game. I’m not saying Ackley will achieve Utleyness. I’m saying that Reed is the cautionary parallel and Utley is the optimistic one. I’m optimistic.
by goyo70 on Jan 3, 2026 6:14 PM EST up reply actions
I was thinking more along the lines of
Ackley being what Jeremy Reed could/should have been, only a bit better. A batting average-OBP machine with 20/20 potential and a good OF glove. That’s a really nice player.
I don’t see the comparison to Utley, either. Seems like a fundamentally different skill set (more raw power, different kind of approach at the plate, less plate discipline). I can see why Utley would be an optimistic outcome - he’d be an optimistic outcome for anybody, as he’s one of the best players in baseball. But other than wanting Ackley to be a “good hitter”, of which Utley is one, it doesn’t work.
I don’t understand why Ackley has to be compared to perennial All Star types. Very few players are deserving of those comparisons, and I don’t quite get why Ackley is one of them. It seems much more appropriate to me to aim conservative and hope for a better version than to aim high and hold unrealistic expectations. Even the best prospects often have issues just being league average players. So please explain to me why Ackley is “potentially great” rather than simply “solid”?
by mrkupe on Jan 3, 2026 6:33 PM EST up reply actions
As you wish
Well, sure. And by this line of reasoning, there isn’t a prospect of whom you would say otherwise, am I right? I agree with you, Ackley seems a solid player. We’ll let him play and see what comes out of the egg.
by goyo70 on Jan 3, 2026 6:58 PM EST up reply actions
of course not
There are players who I grade higher than Ackley, and some of them have the potential to be truly outstanding players. Some would call me a conservative grader, I would regard myself as realistic and objective. I do, however, go out a little more on the ledge for players who show they are worthy of such consideration. Ackley hasn’t done that yet, and honestly, I don’t see what there is to get really excited about. I do like him a fair amount, just not as an impact player. He might still get the B+, haven’t decided yet.

Make or break
year for Dennis Raben as well. The guy is getting sort of old to be at A-ball and even though he hit very well last year in high A, his plate discipline remains questionable and he’ll either need to improve his defense enough to be an outfielder or improve his power enough to be a DH.
Also wonder where Beavan will rank.
by Aslan on Jan 3, 2026 10:43 AM EST reply actions
Raben had microfracture knee surgery last year
He’s really lucky to be playing out field at all. He’s almost 100% DH long term. But his bat isn’t really in question. The guy has legit power and average on base skills. Yes, Jackson is the test for him but I’m not nearly as worried about him as I am Franklin should he be headed to the Southern League.

Biggest Ms challenge
The more interesting questions for this organization are less about the prospects (which are thin) and more about the guys that are right on that cusp of having just graduated.
Smoak, Saunders, Halman, Mangini…if these guys are all busts, the Ms are in deep trouble. But if Smoak turns it around, Saunders improves, and Halman can show some semplance of plate discipline…this organization has some nice pieces.
And, I think Ackley and Triunfel need to turn things around as well. I don’t see this as a very deep system so it can’t suffer any major disappointments and right now things are not looking good.
by Aslan on Jan 3, 2026 10:47 AM EST reply actions
I wouldn't say the M's are thin on prospects.
Just most of their prospects are at lower levels. I don’t think they are in deep trouble if some players bust. Smoak seems more important than the others though, as I don’t see a similarly talented power hitting 1B in the system that is ML ready. Carp and Poythress/Raben seem like other possible 1B candidates but none look like a possible future all-star. They have other outfield options if Saunders or Halman don’t make it. (i.e. Peguero, Chavez) They also have other 3B options if Mangini falls flat. (i.e. Tenbrink, Liddi, Martinez, Morla)
by bp42810 on Jan 3, 2026 2:22 PM EST reply actions
I think they are neither thin nor deep
They have a nice variety of prospects when it comes to infielders and pen arms. The emphasis on finding and developing premium defensive talent might mean that there are a number of players whose bats might show up later than expected. Starting pitching is the biggest weakness in the system - you’ve got Pineda, who has a great arm but is no sure thing, then a very high-upside lottery ticket in Walker, and not much else of note. A better job of managing the 2010 draft would have helped a lot, as the lost pick for Chone Figgins in a pitching-rich class and the failure to sign Ryne Stanek really hurt.
I’m not sure where this system is going to go. Ackley is almost sure to graduate next year and Pineda stands a solid chance of doing the same, and without them, this system suddenly looks pretty bare without some breakouts. I do like some of the players that they’ve added recently (Littlewood is VERY intriguing), but the pipeline of talent isn’t quite what you’d want to see for a major league team that was so terrible last season.
by mrkupe on Jan 3, 2026 5:27 PM EST up reply actions
If Franklin flops, this system could look VERY weak come next year
Two positives: 1) they’ll have a lot of young talent on their major league roster, 2) they have the #2 pick in the 2011 draft.
That being said, I think there are plenty of guys who COULD break out. The performances of Chavez, Tenbrink, Littlewood, maybe even Pimentel could be huge. I still have some faith that Robles or Liddi might breakout as well, but they’re running out of time before they become pigeonholed as relievers/role players.
