The MLB Draft will begin day one of picks on July 11th, the national draft writers are putting out more sourced mock draft reports, so I thought it might be time for a new 20-round Mariner mock.
Let us begin with some of the most recently published mock drafts from national writers.
Jim Callis from MLB.com wrote over the weekend that, “the Mariners are targeting the same college arms as the Cubs” after previously saying the Cubs team and farm needed pitching, “which could lead to college options such as (Liam) Peterson, (Hunter) Dietz, (Tegan) Kuhns or (Cade) Townsend.” And then Callis makes one college arm addendum: “in addition to (Cole) Carlon”. Of that group; Peterson, Kuhns, Townsend are RHP, and Dietz and Carlon are LHP. Callis, with Peterson and Dietz off the board, gives the M’s Kuhns at pick #24.
Keith Law in his mock draft from early this morning went another direction with his rumor: “I’ve heard Seattle as one of the few teams on high school pitching in the first round,” and then specifically cites Carson Bolemon, Logan Schmidt, or Brody Bumila. He doesn’t specifically state they are targeting LHP, but all three of the names he mentions are prep LHP. His last comment is that if not one of the prep LHP; Seattle will “probably” pick a player with an under-slot deal. A couple thoughts: 1) the M’s have never drafted a prep pitcher higher than Ryan Sloan and Sam Carlson both at #2.55. 2) the M’s rarely go underslot with their first pick. Kade Anderson was an underslot deal last year from the #3 overall pick, but he still got $8.8mill. This year; Seattle’s entire draft bonus pool is only $8.2mill for all of the first ten rounds. The idea of the M’s two preferred options being a prep pitcher (who will most-likely cost overslot money) or a player that will sign for underslot money are contradictory. With their very limited bonus pool this year; an underslot pick makes a ton of sense, but then why would they also be looking at expensive prep pitchers. None of this really tracks, to me.
The other national mock I looked at came from a group-effort from the staff at Just Baseball published yesterday. In the alternating mock from four writers; Conor Dorney ends up representing the Seattle pick, and he mentions the M’s on college pitching, and specifies Tegan Kuhns, Cole Carlon, Jack Radel, and with Kuhns off the board; he gives the M’s Cade Townsend.
So after three mocks, the names specifically mentioned for Seattle:
RHP Liam Peterson
LHP Hunter Dietz
2x RHP Tegan Kuhns
2x RHP Cade Townsend
2x LHP Cole Carlon
LHP Logan Schmidt
LHP Brody Bumila
LHP Carson Bolemon
If we sort of Venn-diagram the data points from these three mocks; obviously we’re focused on pitching.
73% of the name mentions are college pitchers.
55% of the mentions are LHP.
45% are RHP and also college RHP.
27% are college LHP.
27% are prep LHP.
The two biggest data sets are college and LHP. Which then points us towards the Venn of Dietz and Carlon. Dietz is off the board before pick #24 in all three of the aforementioned mocks. That leaves us with Cole Carlon.
Carlon is a 6’5″/230lb lefty that pitched ASU to a 3.87 ERA, 1.195 WHIP, 14.3 SO/9, 3.3 BB/9 season line. He features a pitch mix that includes a fastball that has touched 100.7 mph, and a plus slider. There is also a curve and change with lesser present grades. When I watch Carlon; I see a bunch of Gabe Speier mechanically, but obviously Carlon has about 5 mph more velo, and has a full college season of proof of concept that he can start.
Honestly, of the names that have been reported; the two that I personally have been looking at are Cade Townsend and Cole Carlon. I also really like Logan Reddemann, but after he was shutdown by UCLA in April for “arm fatigue”; we’ve not seen him getting much draft buzz in the first round. The Mariners rarely give innings to their early-round pitching draftpicks in the summer of their draft; so I don’t think it’s beyond reason that they would draft a pitcher with a known current injury. Bryan Woo was drafted with a known injury, Brody Hopkins was iirc, to name a couple. But…those guys weren’t drafted in the first round. We can, perhaps, look to do this in a later round.
For now…I’m not too mad at the idea of blending some national reporting on Mariner interests with my own eval. Carlon ticks a lot of boxes. If Seattle were to look at one of the prep LHP (and even throw Gio Rojas in there); I think I might go with Carson Bolemon. Bolemon has the least velo of the three, but probably the best pitchability, and then I just really get the sense he’s a whip-smart, mature for his age young man. He feels like a Cole Young, Colt Emerson, Ryan Sloan kind of personality.
In financial terms on Carlon…I have him in the simulator signing for $3.5mill, which would technically qualify as underslot the $3.8mill allowed for pick #24.
#1.24 = LHP, Arizona State, Cole Carlon
As I just alluded to; I see no reason not to project the Mariners will draft a pitcher with current, known arm injury. Their previous years of pitchers picked in the top two rounds will sit out the remainder of the 2026 summer and fall, with the Mariners overseeing their entire offseason and spring ramp-up.
Jacob Dudan is one of the names that qualify for this. Dudan was shut down by NC State on, roughly, April 4th, and he had Tommy John surgery on April 29th (per his own twitter). He will be down and in recovery for a minimum of a year, which could still see him make his professional debut in 2027. The other thing to consider is the shape of the Mariner’s organization for starting pitching. We literally have a six-man rotation in MLB as of today. Kade Anderson is, arguably, MLB-ready in AA right now. Ryan Sloan is also in AA, but showing some growing pains and needing more time. Logan Evans is on the IL, but still has some upside once he’s back healthy. And, if you’re a psycho for watching prospects like me, LHP Mason Peters has a sub-2.00 ERA across his first ten starts at low-A ball after being picked in the 4th round in 2025 (and also sitting for the summer after he was drafted).
This sounds like an over-abundance of riches in our starting pitching…why am I mocking two pitchers to start this mock? Because I basically just named every starter in the organization that has more than four starts and an ERA under 4.00. (Also: Evan Truitt 3.88, Colton Shaw 3.91, Nico Tellache 3.28, Dylan Wilson 1.86) The Mariners barely have any other starters ranked in their top 30 prospects (Griffin Hugus – yet to pitch, Teddy McGraw – now reliever, Michael Morales – third year in AA, Chia-Shi Shen – struggling in A-, Marcelo Perez – relief, Grant Knipp – relief, Robinson Ortiz – relief, Po-Chun Lin – mediocre in rookie ball, Charlie Beilenson – relief, Tyler Cleveland – relief, Lucas Kelly – relief, Jackson Steensma – injured).
Now…why do I see Seattle making a big, early round investment in Dudan knowing his health status? This guy screams Mariner pitching lab, to me. Listed 6’2″/191lbs, Dudan was touching 99mph this Spring on the sinker while also featuring a plus slider that borders on sweeper from his low-slot release.
Before his injury, Dudan had posted a 3.60 ERA, 1.100 WHIP, 11.2 SO/9, and 2.2 BB/9 in eight starts. I like that Dudan has a three-year sample of pitching in the ACC where he improved his control each year. And in 2026 he made the biggest improvement while also moving from the bullpen into a starting role. This just feels like a Seattle project.
#2.65 – RHP, NC State, Jacob Dudan
In recent years, Seattle has rarely drafted a prep player after the first two rounds with the expectation of signability. Nick Becker pick #57, Ryan Sloan pick #55 were second rounders. Before that: Aidan Smith pick #124 in 2023, Ashton Izzi pick #126 in 2022, Tyler Gough pick #276 in 2022, Michael Morales pick #83 in 2021. That’s it for the last six drafts. So it’s a little bit contrary to their trends to project any prep players from here forward. But I kinda like waiting to do it. Waiting to go prep player this year is additionally tricky due to our low draft bonus amount. We can, basically, draft four players that we can offer over a $1.00 mill bonus to, as long as the rest of our draft kind of focuses on “senior-sign” types that we can give minimal bonuses to.
As I said earlier; I’ve been running simulations for the Mariners this year, and the primary simulator available online includes a bonus element. The program essentially gives every college player ranked after the top 300 prospects a default bonus of $150k. MLB teams can technically give a player a bonus as low as they want (that the player agrees to), but I actually like giving them a floor of $150k. I mean, do you really want to draft a guy that is willing to sign for $25,000?? The chances of that player panning out are slim to none, and the difference between doing that and giving a three-year, living wage type bonus to a guy that has SOME upside is, like, $100k. Just do better accounting. And the Mariners have been, more or less, following this philosophy recently. In 2025, the M’s gave a minimum bonus of $50k to any single draftpick (17th round), and a minimum of $100k to all of their picks in the top 10 rounds. They gave bonuses of exactly $150k to six picks (rounds 11, 12, 13, 15, 16, 20).
The advantage of pushing prep players down to later rounds is that you can end up getting an appropriately ranked/drafted college player in the early rounds AND still getting a higher ranked prep player in a later round and just pay them the bonus of an early round pick. This, in theory, means we can get five top 100 players when we only have three picks in the top 101 overall (for example). The disadvantage of this strategy is that some prep players want BOTH the signing bonus money and the symbolic meaning of being an early round pick. You have to know your board and prenegotiate which players will still sign from a later round pick.
The most recent example of this was Aidan Smith in 2023. Smith was ranked the #78 overall player on the MLB big board. Seattle drafted him at pick #4.124, and they signed him for $1.2mill when slot money was $531k.
The other thing to consider in the prep player conversation is simply how terrible Seattle has been at developing the prep pitchers they have drafted over the years. Like, all of MLB kinda has trouble developing prep pitchers, but Seattle definitely has zero hits doing it in the Dipoto era. So it’s just terrible ROI to do it. Now, do they have a better argument about developing prep HITTERS? Certainly it feels like they have a stronger argument this year when Cole Young and Colt Emerson are representing 50% of their MLB infield, and Julio Rodriguez was developed from his teenage signing as an international player.
With all of these factors in mind; I like the way the board lines up this year to have select spots across the draft where I’m filling gaps in my college board with overslotted prep players. And those happen to be more of the hitting variety.
The first prep player I’m drafting is Mill Valley 3B, Beau Peterson. It’s not always easy to find prep players’ season stats, but I think I have a fairly accurate listing of Peterson’s season as: .535/.650/1.536 slash with 3 HR, 26×29 SB, 28 BB, and only 5 SO. I thought he was gonna have a better power number as he has previously won a high school homerun derby in one of the HS exhibitions. Regardless, I’m happy to draft the hit tool and look to add some game power.
#3.101 – 3B, Mill Valley HS, Beau Peterson
The fourth round is an interesting pivot point for me. I lowkey think we need to add another starting pitcher because those names dry up quickly after this if we don’t. But that would make three SP in our first four picks…should it be a bat for balance? The Mariners rarely target balance in their drafts. They will go hard on SP if the draft calls for it. They will draft three or four prep bats if the class and their bonus pool allow for it. Those logical thoughts don’t necessarily come into play like we think they might.
Having said all that…when I ran the simulation; I found the most exciting player consistently available to draft at this pick is actually a reliever.
#4.129 – RHP, UCLA, Cal Randall
Cal Randall is a thickly built 6’4″/235lb righthander that pitched in 34 games in 2026 where he posted a 3.19 ERA, 1.097 WHIP, 16.5 SO/9, 5.5 BB/9. He actually gives up more walks than he does allow hits for the year. He works primarily from a double-plus fastball that touches 101mph, and has exceptional metrics in terms of release height, extension, IVB, etc. He also throws a change-up and a slider. If the pitching lab can do similar for Randall what they’ve done for Brock Moore (5.8 BB/9 as senior at Oregon, 3.0 BB/9 between Everett and Arkansas in 2026); they’ve got a future closer on their hands. And a quick mover through the minors.
At this point of the draft; my board suggests we can really start rolling through some underrated, high upside college bats. I think you always want to draft a catcher in the top six picks, or so, and that ends up lining up nicely to be my first pick in this stretch.
#5.165 – C, Cal Poly, Ryan Tayman
Tayman is listed 6’2″/210lbs, and has a really nicely balanced skillset as hitter and receiver. He is only 20 years old, but has two years at Cal Berkeley before this year at Poly where he hit .357/.447/1.119 with 18 HR, 19 doubles, 31 BB, and 50 SO. He was the central figure in the Mustangs roster that made a run in the College World Series in the last couple weeks.
#6.191 – OF, Pitt, Lorenzo Carrier
Carrier is just one of my favorite bats in this whole draft. Listed at 6’5″/215lbs, Carrier hit .387/.534/1.318 with 20 HR, 15 doubles, 6×6 SB, 57 BB, 62 SO on the year. The only reason he is hypothetically available this late is that he is already 23 years old as of May, and maybe he’s limited defensively.
#7.220 – RHP, St Joseph’s, Christian Coppola
Honestly, I’d be a little surprised if Coppola was available this late. He’s a 6’5″/230lb righthander that primarily pitched in relief in 2026, but who had 25 starts for Rutgers between 2023-24, and recently made a three-inning start for Trenton in the summer MLB Draft League. There may be a chance he goes back to starting, which is a big part of why I want him after choosing to draft a reliever over a starter in the 4th round.
In 2026, Coppola finished with a 1.69 ERA, 0.884 WHIP, 16.6 SO/9, and 2.9 BB/9 in 12 relief apperances and one start for St Joseph’s.
#8.250 – 1B/C, Miami, Alex Sosa
I’m acknowledging Sosa has experience as a catcher, but every time I watched the Hurricanes from, say, March until their season ended in the CWS regionals; Sosa was playing 1B. If Alex still has some catching innings left him that’s an awesome bonus cause he hits lefthanded, and that is always a nice commodity to have. Listed 6’1″/208lbs, Sosa hit .338/.448/1.119 with 18 HR, 16 doubles, 41 BB, 48 SO for the year. If he ends up only playing 1B…fine. He has the power to be a decent weapon (a la Josh Naylor) as a 1B.
#9.280 – SS, Magnolia Heights HS, Christian Doty
The Mariners have had some of their best draft success going after prep shortstops, and so I have them drafting another one (with some hidden value being available late in the draft) in Doty. Listed at 6’1″/190lbs, Doty has one of my favorite righthanded hit tools in this class. He comes from Olive Branch, Mississippi which may sound familiar to Seahawk fans who might recognize Olive Branch as the high school origin of former Seahawk, KJ Wright.
Again, stat lines on prep players can be hard to find, but I show Doty’s 2026 season as: .492/.609/1.351, 6 HR, 20×20 SB, 27 BB, 10 SO. He has a college commitment to Ole Miss, so we will of course need to give him overslot money. The simulator I use doesn’t allow you to alter the bonus money offers to players, so the screenshot below will show him at an even $1.0mill bonus, but you will also be able to note that I finished the top ten picks with $310k of surplus…all of that will also go to Doty to bring his bonus up to $1.3mill.
There is a glitch in this mock draft simulator where most of the rankings after like #250 have duplicate names. So there are two players that are listed as #386 on the simulator big board, Christian Doty and Tyler Albanese. The correct player shows up as the simulation rolls (see directly below), but then it is the other player at the conclusion of the draft, which I also show further down.

#10.310 – RHP, Oregon State, Isaac Yeager
Oregon State had a really nice pitching staff this year, and I seriously considered multiple names from their team across this whole mock. I like LHP Ethan Kleinschmit in the 2nd or 3rd round, I like RHP Eric Segura in the 4th round slot where I took Randall. I like reliever Wyatt Queen wherever we can get him.
I ended up only mocking Yeager, but I’m really happy to get him. He’s a former UW Husky who originally comes from Bishop Blanchet HS in Seattle, so this will be a homecoming for him. Listed 6’6″/255lbs, Yeager looks more like a Husky tightend than a reliever, but he had a 2.04 ERA, 0.908 WHIP, 11.1 SO/9, 2.5 BB/9 for the year. He throws a fastball sitting 95mph, and a plus slider as his out-pitch.
Here is the screenshot of my simulation run of the top ten round picks.

#11.340 – SS, Nebraska, Dylan Carey
With the signing of Christian Doty potentially a question mark; it’s important that we draft another shortstop that we know we can sign because, ultimately, we still have to fill a farm system with players that can play innings for the next three years, or so.
I actually really like Carey. He’s one of three college SS this year that I found that I really ended up liking for their on-field skills and intangibles. There was Tyson Leblanc who was the clutchest hitter for the Kansas squad that made a deep run in the CWS, and who is now projecting to be off the board before pick #65. There was Jake Schaffner who played SS for North Carolina and who has a really nice glove. And there is Carey who seems to be the one with the lowest profile that we can still get outside of the top ten rounds.
Carey hit .353/.428/1.050 with 15 HR, 16 doubles, 21 BB, 49 SO this year. He also plays a very solid defensive SS.
#12.370 – C, VMI, Cole Raile
Even if Alex Sosa ends up playing some catcher; I don’t think it’s terrible for Seattle to draft three. They end up being useful trade pieces. Seattle drafted three catchers in 2025 (Luke Stevenson, Luke Heyman, Grant Jay) and have already traded Heyman to Boston in the Alex Hoppe deal.
Raile is really an interesting player. He’s one of the more athletic catchers you’re going to find. He has power (16 HR), he has a great arm (33% caught stealing), and he can run (24×26 SB). We probably can’t get him this late, but c’est la vie.
#13.400 – 1B, Baylor, Tyce Armstrong
Armstrong is another guy I have no clue of his true value. Most draft boards don’t even list him, which could mean he’s lower than top 500 names, but he hit .338/.453/1.211 with 24 HR, 14 doubles, 35 BB, 54 SO, so why wouldn’t MLB teams want him at decent price? Like, this isn’t a profile of a guy that is selling out strikeouts to get to his power. He’s a little overaged in that he will be 23 the week before the draft, but that’s a minor issue in my opinion if the upside holds, and he moves fast.
#14.430 – RHP, Clemson, Hayden Simmerson
Simmerson was a recent find for me and I’m wondering why he’s not ranked higher, but whatever. I don’t make the rules and I don’t make the bugs. Simmerson is listed 6’2″/205lbs and had a 3.62 ERA, 0.897 WHIP, 12.8 SO/9, 3.1 BB/9 with 4 saves in 19 relief appearances.
#15.460 – LHP, Bowling Green, Ethan Stade
It’s always good to look for depth lefthanders, especially if they can start. Stade had a 4.36 ERA, 1.141 WHIP, 14.5 SO/9, 2.8 BB/9 in ten starts and four relief appearances. The peripheral numbers are better than the ERA.
#16.490 – RF, Miami Ohio, Tommy Harrison
Harrison had a massive season playing in the MAC this year, but he’s showing his flaws after 16 plate appearances in the MLB Draft League. In the college season he hit .386/.507/1.205 with 17 HR, 16 doubles, 41 BB, 33 SO.
#17.520 – RHP, Coastal Carolina, Darin Horn
Horn is an interesting profile. He’s listed 6’4″/200lbs and had a 3.21 ERA, 1.262 WHIP, 12.4 SO/9, 3.2 BB/9. He doesn’t have much velo, but he does enough with movement and deception that he strikes guys out. His ceiling might be kind of a Cooper Criswell profile, but that’s well worth the pick this late.
#18.550 – LF, Northeastern, Harrison Feinberg
When I discovered Feinberg I really liked his game. Listed 6’1″/210lbs, he hit .331/.440/1.037 with 16 HR, 15 doubles, 42 SB, 37 BB, 52 SO. And the guy plays all out on defense.
#19.580 – RHP, Seton Hall Prep, JJ Drennan
With the structure of this draft; you basically need to draft a prep player late like this as a guy you can offer big money to in case one of your prep players from the top ten rounds falls through and you end up with a bunch of surplus bonus money. I figure it’s better to try this move with a prep pitcher than hitter because of the Mariners’ reputation for developing pitching. Drennan is from New Jersey and has a commitment to Boston College. Neither of those is known as a hotbed for baseball talent, so there might be a bit more flexibility to sign him away from his college commitment.
#20.610 – 3B, Toledo, Troy Sudbrook
Sudbrook is 6’3″/205lbs and hit .373/.467/1.132 with 11 HR, 32 doubles, 13 SB, 30 BB, 40 SO. Seattle doesn’t really draft and develop third basemen, they prefer to draft shortstops and convert them, so I like drafting one with the knowledge he already is a 3B.
I’m currently pretty happy with this mock. It’s fairly balanced, which I generally like even though Seattle will never necessarily force a balanced draft.
I predominantly think the best players available in the first round are pitchers…either prep or college. I would love a Logan Reddemann pick.
I think there are interesting options in the second round. I love Texas catcher Carson Tinney, but a second round catcher feels rich with Cal Raleigh in the bigs and a Luke Stevenson pick in the second last year. I think prep outfielder Blake Bowen would be super interesting as a guy built like a linebacker but who can hit, run, and throw at elite levels.
I really like LHP Ethan Kleinschmit if he falls to the third round.
I really like a number of college RHP starters in the fourth round including Declan Dahl, Eric Segura, Cal Scolari, Josh McDevett, and maybe Dylan Vigue if the Seattle pitching lab can fix him. Also a Minnesota RHP named Isaac Morton, who also I believe has needed TJ surgery recently.
I like a number of prep pitchers at various rounds. I like LHP Carson Bolemon a lot. I like Kaden Waechter, who reminds me a bit of Bryan Woo. I like Kaiden McCarthy who is a 17 year old that reclassified to the 2026 draft, and likely WANTS to sign, and who already is touching 99mph. I like Washington prep pitcher Eli Herst. I like a guy named Harrison Pollina, who isn’t even on the list of over 1000 players within the simulator I used.
And there are so many college bats I like that kinda feel like they fall in the no-man’s-land areas between Seattle picks, but don’t seem worthy of a reach, but also don’t seem likely to drop to the next round’s pick. Andrew Williamson, Ace Reese, Logan Hughes, Caden Sorrell, Tyson Leblanc, Gavin Grahovac, Dee Kennedy, etc. But when I like my later round guys as much as those top, say, 125 names…I just would rather take the pitcher early because I don’t have the midround pitching names that I like as much. So this is where I end up.
