Even after trading some quality prospects and having a few players graduate from having eligibility, the Seattle Mariners still have one of the best farm systems in baseball. In fact, I would argue that they still have the best system in baseball, and the fact they were able to retain that status even while getting the top two bats on the market (Eugenio Suárez, Josh Naylor) and a very good reliever (Caleb Ferguson) is pretty dang impressive.

I update my top 15 prospects every month over at My Oh Why, but I thought it’d be fun to share the 10 prospects who just missed that list. We’ll go in reverse order, because it’s more dramatic that way.

### 25\. Jared Sundstrom, OF, Double-A Arkansas

**2025 stats**: 85 G, .231/.306/.389, 9 HR, 27 SB, 29 BB, 98 SO

Sundstrom has seen his stock drop a bit due to a mediocre 2025 campaign, but there’s reason to believe he could someday be an MLB contributor. He’s a solid athlete with above-average speed, and he is capable of playing all three outfield positions. He shows the potential for solid-average power, but his approach has gone backwards after drawing 71 walks and forging a .380 on-base percentage in 2024\. Right now, Sundstrom projects as a bench outfielder or up-and-down player, but there’s a little more upside in his bat than you might expect from a 24-year old in Double-A.

**ETA**: 2026

### 24\. Luis Suisbel, INF, High-A Everett

**2025 stats**: 87 G, .230/.330/.442, 18 HR, 5 SB, 40 BB, 96 SO 

Suisbel was given a $350,000 bonus back in 2019, and he’s slowly but surely developed into one of the more intriguing infield prospects in the system. He’s a switch-hitter, and he’s tapped into above-average power from the left side, although he’s not completely bereft of pop as a right-handed hitter. He’s improved his patience at the plate, and there’s enough hard contact to suggest he can get on base at a decent enough clip. He’s played at first, third, and shortstop with Everett in 2025, but his most likely landing spot is the hot corner. His ceiling is a second-division third baseman, but there’s a decent floor as a bench bat who can provide some extra-base hits from the left side of the plate.

**ETA**: 2027

### 23\. Carlos Jiménez, OF, Low-A Modesto

**2025 stats**: 88 G, .266/.363/.440, 13 HR, 22 SB, 48 BB, 96 SO

Let’s get the most negative out of the way. Jiménez turned 22 in February, and that’s too old for a player playing in the California League. But he’s a weird case as a player that had to wait to make his pro debut because of the pandemic and didn’t come over from the Dominican Southern League until 2023\. And, ultimately, Jiménez is a player that often passes the eye test. He’s a well above-average athlete, and he shows a quality approach at the plate with the ability to use the entire field from his left-handed swing. The power is a question mark, but 15-to-20 homer seasons wouldn’t be out of the question, and 30-plus steal seasons could come with it because of his speed. We need to see Jiménez handle the higher levels before getting too excited, but there’s no question he’s seen his stock rise in 2025.

**ETA**: 2028

### 22\. Victor Labrada, OF, Triple-A Tacoma

**2025 stats**: 95 G, .288/.402/.418, 7 HR, 35 SB, 61 BB, 69 SO

Labrada will not be the only point-guard sized player on this list, but the 5-8 outfielder is one of the better prospects in Tacoma. He’s a double-plus runner, and he’s the type of player you often see used as a pinch-runner in late-game situations. He can go get it in the outfield, and the 25-year old could handle center while also being an asset in either corner. He’s made a concerted effort to cut down the strikeouts, and a player who fanned 101 times in as many games last year has done that while also drawing a career high in walks. There’s not much power in his left-handed bat, but he has a chance to compensate -- to an extent -- because of his ability to get on base and make enough hard contact for a solid average. Labrada is probably nothing more than a fourth outfielder, but there’s certainly value in that type of profile.

**ETA**: 2026

### 21\. Chia-Shi Shen, RHP, Low-A Modesto

**2025 stats**: 12 G, 51 IP, 3.53 ERA, 48 SO, 10 BB, 1.08 WHIP

Seattle gave Shen a $175,000 bonus out of Taiwan in 2024, and he’s quickly looked like an arm that should have gotten much more than that on the open market. He’s a 6-3 right-hander who already touches 95 mph with his fastball, and there’s likely more to come as he fills out his frame. His best pitch is a change that gets plus grades from scouts, but he does show a slider that is lacking in consistency, but occasionally flashes in that range. He throws everything for strikes, and he repeats his delivery exceptionally well for a player without a ton of pitching experience. He profiles more as a backend guy at this stage, but an improvement in velocity and/or more consistency with his breaking-ball could see a bump in his stock. If not, I’d be very intrigued to see what Shen can do out of the bullpen.

**ETA**: 2028

### 20\. Korbyn Dickerson, OF, 2025 Draft Pick

**2025 stats**: 56 G, .314/.381/.632, 19 HR, 5 SB, 24 BB 51 SO at Indiana University

Dickerson was the Mariners’ fifth-round pick, and in my humble estimation, one of the best value picks in the class. He put up some of the best exit velocities of any draft-eligible player in 2025, and he shows the type of power/speed combination that you see from starting outfielders. He also has a strong throwing arm, so while it’s likely Seattle will give him a chance to play center, he would be an excellent right fielder if he was to make the switch. There’s a considerable amount of swing-and-miss, and it’s worth noting that he struggled against the harder throwing players he faced. He’s not your typical college bat, as Dickerson is more about ceiling than floor. There’s a wide range of outcomes here, but it’s a very exciting profile.

**ETA**: 2028

### 19\. Dawel Joseph, SS, Short-season DSL

**2025 stats**: 44 G, .201/.368/.313, 3 HR, 15 SB, 32 BB, 57 SO

Joseph is a tough player to rank, in part because I’m relying almost entirely on reports on top of some of the stats. And as you can see, the stats aren’t all that good. However, it’s important to remember that this is a player that just turned 18 in May, and there’s a reason Seattle gave him a $3.3 million bonus in January of 2024\. The tools are obvious, and it’s encouraging to see that he’s willing to draw free passes. It’s also a vast improvement over 2024 when Joseph hit just .133 with a .447 OPS in his 47 games in 2024\. There are five potential above-average tools here, and he’s a quality athlete who should be able to stick at shortstop. It’s just a complete unknown if he’ll ever live up to that hype. There’s a wide, wide, wide range out outcomes here, but he’s someone fans of Seattle should pay attention to.

**ETA**: A long time from now

### 18\. Michael Morales, RHP, Double-A Arkansas

**2025 stats**: 16 G, 68.2 IP, 4.59 ERA, 27 BB, 44 SO, 1.43 WHIP

Morales is the opposite of Joseph in a lot of ways, but in particular the way we talk about ceiling and floor. We pretty much know what Morales is: he’s a right-hander who is difficult to square up with a five-pitch mix, and he generally locates those pitches where he wants. He’s also a player who just hasn’t missed bats whatsoever in 2025, and with none of his pitches flashing plus, it’s unlikely that changes at the highest level. There’s a chance the stuff plays up in relief, but Morales projects as a backend starter for now. There are definitely worse things, but it’s a little disappointing considering the upside Morales showed when first drafted with the 83rd pick of the 2021 draft.

**ETA**: 2026

### 17\. Kendry Martínez, SS, short-season DSL

**2025 stats**: 32 G, .163/.316/.174, 1 SB, 18 BB, 33 SO

The stats -- like Joseph’s -- are not impressive. The talent -- again, like Joseph’s -- is. Martínez was given a $2.5 million bonus in January, and while he hasn’t hit at all in his 92 at-bats, that sample is hard to take too seriously. His smooth, line-drive swing suggests he will hit for average as he gets stronger and gets better at recognizing spin, and while his frame (5-10/157) suggests he won’t be much of a power hitter, there’s enough bat speed to project double-digit homers as he matures. He’s a solid defender according to sources, and he gets quality reviews for his baseball acumen. Again, there’s a long way to go and there’s a boatload of volatility because he’s a 17-year old on top of baseball being really hard. But Martínez has the potential to be a well above-average starting shortstop if everything goes right. We have no idea if everything -- or anything -- will go right.

**ETA**: 2030

### 16\. Brock Rodden, INF, Double-A Arkansas 

**2025 stats**: 34 G, .298/.369/.443, 4 HR, 15 SB, 13 BB, 45 SO

Rodden is the “other” shorter prospect on this list as a 5-7 infielder, but he’s one of my favorite prospects in the system for a lot of reasons. Despite his diminutive stature, he projects to put up average power numbers with the ability to put the ball into the gaps. He’s a smart hitter who used the entire field with an assertive approach at the plate, and it wouldn’t shock me if the hit tool was plus at the highest level. I’m not sure where he’s going to play defensively, but it’s not hard for me to see him being a solid defender at second and third who can fill in at shortstop as well. I can see Rodden being an average starting second baseman, but I can also see him being an excellent utility player. He doesn’t get nearly enough attention.
