Mariner mock revisions

By Jared Stanger

As I’ve just been digging around for draft intel and data and any kind of potential edge prior to Sunday’s first night of the MLB Draft, it occurred to me that I’ve missed one type of process point in my prior mocks.

The MLB has set up a rule wherein the players that attend the MLB Draft Combine and submit to the physical portion of the process will be guaranteed to be paid at least 75% of the slot bonus for whichever pick they’re chosen at. This somewhat limits MLB teams’ option to pay these players “underslot” deals. This is primarily beneficial for the senior college players that would otherwise have little negotiating power after using up their college eligibility. This was, specifically, relevant for two players in my most recent mock that I am going to adjust for here.

I’m also saying fuck it to acknowledging what I think Seattle will do. This is my taste and my structure of how best to hack this draft class. Seattle is potentially going to draft for “need” to an extent. Nothing that the MLB team needs right now is going to come from this draft, nor is anything in this draft going to overtake what is already in the minor league system. If we want players that will affect the 2026 roster; we need to trade prospects for major league players. This mock is simply, in my opinion, the best way to pick the best future MLB roster.

#1.3 – SS, Corona HS, Billy Carlson

Seattle probably drafts one of the college LHP here, and that might be good for the eventual structure of their whole draft, but I just can’t get over how smooth and polished Carlson is with both the glove and the bat. He feels like one of the few guys at the top of this tepid draft top 10 that has true upside. He has so much body control…all we need is to see him get stronger and his pure current launch angle line drives will become homeruns.

Carlson is ranked #7 on the MLB board, so another part of the idea here is that we should sign him for under the $9.5mill bonus slot. I’ve budgeted him for $8mill.

#1.35cb – RHP, Louisville, Patrick Forbes

Forbes might be the key to this whole draft. If he’s still on the board at #35; I struggle to see the Mariner pitching lab not latching on to him, even though they could start trying to take overslot high school players here. I think I may have reached a new understanding of how Seattle scouts pitching, and if I’m right…Forbes will be a guy they covet.

Forbes has college eligibility remaining, so he will still require a decent signing bonus. I’m giving him slightly below the slot of $2.75mill with a bonus of $2.5mill.

#2.57 – LHP, Johnson HS, Johnny Slawinski

Part of the reason I’m passing on the college LHP at #3 is because I think, longterm, Slawinski will be better than them. The only reason he isn’t a bigger deal right now is because of velo. But, also, what a contradiction that the #1 college LHP, Kade Anderson, has gotten there because of pitchability over velo, and yet, somehow, guys like Kruz Schoolcraft and Jack Bauer are ranked higher (#19 and #44) on the prep lefty board than Slawinski (#68) who has the better pitchability of those three. Whatever. Market inefficiency that I’m hoping to exploit.

Seattle signed Ryan Sloan away from his college commitment at pick #2.55 last year, and a bonus of $3mill. I’m doing the exact same figure for Slawinski at #57…$3mill. This equates to a top 32 pick bonus.

#3.91 – OF, Purvis HS, Jacob Parker

I started including this half of the Parker twins in my last mock, and I’m going to keep him here. I had tinkered with some prep righthanded power hitters; but I was struggling to justify the swing and miss on most of those specific players.

Parker, on the other hand, has one of the strongest overall profiles in my database for this prep class. He’s underrated in a lot of facets, but certainly his power is unquestioned. I’m offering him an overslot bonus of $1.22mill.

#4.122 – RHP, UNCW, Zane Taylor

Taylor is one of the picks that I’ve had to adjust my drafting on. He is one of the guys that is a senior, but who is gonna be guaranteed at least 75% of the bonus for the slot where he’s picked. I’ve also moved him up a round because I think I had him underrated.

The slot for this pick is $617,200, so I’m giving him just over the 75% figure with a signing bonus of $465,000.

#5.152 – RHP, Baylor, Gabe Craig

In my previous mock, I had Seattle drafting Tennessee reliever Tanner Phillips who brings over a 100mph fastball and could move really fast to the show. Phillips is not a senior and would be guaranteed 75% of slot, so I just don’t know that I can afford him.

Craig is actually one of the highest-scoring pitchers in my entire 2025 college database. He is 24 years old and was not at the Draft Combine, so we can give him the full senior-sign treatment. Last year, Seattle used a couple of relievers (Hunter Cranton and Charlie Beilenson) to save bonus money in this same range of the draft. Those guys got $50k and $25k respectively. I’m not going that hard on Craig, and I can offer him $150k. This still saves Seattle ~$350k for other picks.

#6.182 – C, Wright State, Boston Smith

Smith is a longtime carryover from my previous mocks. He should be a true senior-sign player as a 22 year old who was not invited to the Combine.

As a lefthanded, power-hitting catcher that has good catch and throw tools; I’m super psyched to add him to the system.

#7.212 – RHP, Shawnee Mission HS, Michael Winter

Winter is a 6’5″/220lb pitcher coming out of Kansas with a really impressive present three-pitch mix. Similar to Slawinski; I love the pitchability more than the current velo. I think Seattle has struggled developing high school guys that come out of their senior year(s) with 97+ kind of velocity (Walter Ford comes to mind). I would like to try the opposite. Let’s draft guys that know how to pitch/spin and see if we can teach them to throw harder.

Winter has an unusual commitment to Dartmouth, but he did attend the Draft Combine, which may speak to an interest in signing if the price is right. I’m offering him $1.20mill, which correlates to approximately the #70 pick’s bonus.

#8.242 – LHP, Florida, Pierce Coppola

Coppola is a frequent returner to my mock drafts. I am adjusting his bonus to reflect his status as a guaranteed 75% senior from the Combine. I will give him $170k and work to come up with a program that can keep him healthy enough to continue to be a starter. If not…maybe he might thrive with a bullpen role.

#9.272 – RHP, Vanderbilt, Sawyer Hawks

Hawks is a return to the full-fledged senior-sign players. Another 22 year old, reliever-only, that was not at the Combine, we can sign him for basically whatever amount we want (and he agrees to). I’ve budgeted the very specific amount of $129,400.

#10.302 – 3B, Rhode Island, Anthony Depino

Depino falls, somewhat, victim to the MLB Draft rules that give very few options to a player of his age and the college he attended. He gets the smallest bonus of my top 10 rounds with only a $90k bonus.

#11.332 – LHP, Georgia, Alton Davis

The 11th round is frequently one of the more interesting picks in a Mariner draftclass. It’s the first pick of the draft that doesn’t count towards their overall bonus pool. There is no penalty for not signing the player drafted here, while simultaneously, there is more talent still on the board here, obviously, than the 12th-20th rounds. You can draft an overslot guy here if you think you have savings, while not being overly concerned that this pick will affect the others.

Davis is a bit of a wildcard. He has never performed to a level that gives him a high floor. He’s a pretty pure upside pick. You’re hoping you can take his 97mph fastball from the left side, and his plus slider, and you can get him to throw more strikes with them. In 2025 in the SEC, Davis got hit around more than 2023 Mariner 12th round pick, Logan Evans. But Seattle saw enough in Evans to get him figured out to the point he has made it to the show in under two years. Evans was primarily a starter for Pitt, whereas Davis has only really pitched out of the bullpen in college, but Alton has currently made three starts in the MLB Draft League, so maybe there is an outside chance he continues doing that.

The bonus for all picks in rounds 11-20 is slotted for $150k. Teams can go over that figure, but all overages count toward their top 10 round pool.

#12.362 – 1B, Loyola Marymount, Beau Ankeney

Most of the rest of this mock will match what I wrote last weekend. I’m not describing a specific bonus amount unless I expect the player to need overslot money.

#13.392 – OF, Youngstown St, Kyle Fossum

See previous mock.

#14.422 – 2B, UConn, Ryan Daniels

See previous mock.

#15.452 – RHP, Dax Dathe

In the days after my previous mock; a couple of things happened. I saw more video of Dax Dathe pitching in the MLB Draft League that looked pretty great, and my previous projected pick at #452, RHP Max Grubbs, announced that he is withdrawing his name from the draft to remain at Texas.

Cool. Easy one-for-one swap.

#16.482 – OF, Southern, Cardell Thibodeaux

See previous mock.

#17.512 – LHP, St Joseph, Colton Book

See previous mock.

#18.542 – C, Georgia State, Colin Hynek

See previous mock.

#19.572 – LHP, Northeastern, Jordan Gottesman

After going away from the mock with the college LHP in the top pick; I made a choice to hunt for lefthanded college starters whenever I could. Gottesman doesn’t have some of the pitch metrics I think Seattle looks for, but he’s certainly had pretty strong results in the 2025 season. Across 83 innings he finished with a 2.27 ERA, 0.864 WHIP, 10.5 SO/9 and 1.8 BB/9. Maybe the performance staff can build up his strength and/or flexibility in order to tap into a bit more upside.

#20.602 – CF, UTSA, Mason Lytle

See previous mock.
