There was a report that surfaced this week breaking down MLB’s plans to restructure the entirety of amateur player acquisition as part of the impending CBA expiration and subsequent renegotiating. A few of the major points of the proposal for the domestic draft:
-banning the drafting of prep players altogether, and effectively making draft eligibility start at a player’s age of 20.
-shortening the draft from 20 rounds to 12 rounds.
-cutting the available signing bonus pool by more than $150 million per year.
-hard-slotting the bonus amounts rather than the current system of suggested slot bonus.
I haven’t heard/seen anyone thinking these ideas are good outside of Rob Manfred who is acting on behalf of MLB owners. The idea of installing a draft in place of the international signing period is particularly inconvenient for the Mariners who are projected to sign three of the top international prospects, including Mairon De La Rosa, who Seattle recently sniped from the Yankees when their verbal agreement fell apart. Under the MLB proposal, the 2027 signing period (typically in January of each year) would disappear completely, to be replaced by a draft that would take place in September 2027. They would also raise the international age eligibility from 16 to 18, thereby making all of Seattle’s 2027 agreements ineligible until, at least, 2028.
None of the reported draft changes would affect the 2026 domestic draft. At least, that’s what I was initially thinking. But as I’ve spent some time dwelling on these proposals; it occurs to me that their leaking into the media and then into the common knowledge could actually affect this year. Players coming from the 2026 high school draft class may now be incentivized to sign with their drafting MLB team for higher bonus amounts in 2026, than to risk the possibility of a slashed bonus pool, if not a hard-slotted possibility, should a new CBA pass as proposed.
Savvy MLB teams may seek to take advantage of these conditions and look to stock up on prep players this year, before their option to do so goes away entirely or even changes towards more restrictive. The only thing within the MLB’s reported draft restructure that benefits the players themselves would be the change in eligibility for college players from “after three years of college” to “after two years of college”. That proposal, in concert with the recent change in NIL money for college athletes, may be enough to sway 2026 prep players into honoring their college commitments this cycle. But, as far as I can tell, college baseball players aren’t cashing in on NIL money like, say, college football players. At the high end of baseball NIL money, my research suggests elite baseball players are making more like a max of $500,000 a year. Multiply that times the required two-years in college; and an elite college player is looking at, maybe, $1,000,000 in college earnings. So any 2026 draft bonus north of a million dollars could be enough to get most prep players signed to their drafting team this summer. In theory.
With this in mind…will it be possible for Seattle to sign an elite prep player at pick #24 for a techinically underslot figure?? The suggested slot bonus for pick #24 is $3,818,700. Could the Mariners find themselves with more prep options willing to sign at that pick for, say, $3.2million? An underslot deal in the first round is particularly appealing for Seattle this year as they currently don’t have a large bonus pool available. The Mariners’ total bonus pool is $8,218,200, which is the seventh-smallest pool in MLB this year. Saving money in the first round will make it easier to double, triple, quadruple down on prep players for the entire draft.
As I did in my last mock draft; I am cross-referencing my theoretical draft plan with a simulated mock draft via Over-slot.com. Their program includes a bonus element, but that element is non-negotiable. So the dollar amounts listed could vary widely from eventual actual bonus amounts.
#1.24 – LHP, Southside Christian HS, Carson Bolemon
Maybe a week ago Keith Law published a mock draft with the Mariners taking Bolemon here. At the time, I found the pick somewhat unresearched, as Seattle has never drafted a prep pitcher higher than pick #55 in the Jerry Dipoto era. But, if my new overriding theory of this draft is true, in light of this week’s news; Seattle may very well be considering prep players of either discipline earlier and more often than they ever have before. And…said pick(s) may cost less than ever before, so it could be two birds with one stone.
Bolemon ticks a lot of boxes for Seattle at #24, but one of those is how rarely they will reach and draft underslot players with their first round picks. Kade Anderson wasn’t a reach last year, but they did end up getting him for an underslot figure. Bolemon is ranked the #23 player in the class by mlb.com. Getting him at pick #24 is appropriate value, and then the signing bonus is TBD. My theory is that Bolemon will sign for underslot, but my simulator mock budgets for him to get exactly slot. So we can handle either pathway.
As a player, Bolemon reminds me of a very specific pitcher. I’m not going to reveal who, but suffice to say he would make a great pick. The calling card for him here, for me, is the overall pitchability. With the asterisk being the future upside including the potential to add some velo.
#2.65 – 3B, Mill Valley HS, Beau Peterson
Part of the hack of the draft simulator is that they place a bonus floor on certain rounds, so it actually benefits your overall mock to draft a high bonus player in the second round. You can’t aggressively underslot this early. So I’m adjusting my strategy to go prep-prep with the first two picks.
Peterson has a really strong hit-tool in his high school season where he hit .535/.650/1.536 with 3 HR, and 26 SB. The interesting thing is that he was also the winner of the high school homerun derby last year. So there is power within, but he’s not selling out average to get to his power. That’s tremendous discipline for a teenager.
#3.101 – OF, North Carolina, Owen Hull
I’ve started to think Seattle might be targeting outfield help with one of their early picks. That thought has coincided with my tendency to recency bias players that excel in the various stages of the College World Series. Owen Hull has been one of the biggest stars in the CWS and has now led the Tar Heels to this year’s Finals. On the season, Hull has hit .398/.506/1.121 with 8 HR, 26 doubles, 85 RBI, 18 SB, 47 BB, and 44 SO. In 2024 and 2025, before his transfer to UNC, Hull stole 42 and 29 bases for George Mason. So there’s a bit more speed there than, perhaps, the 2026 season might suggest.
Hull could be a true centerfielder with leadoff hitter traits. The Mariners current outfield situation has Randy Arozerana a free agent at the end of this season, Victor Robles has a club option for 2027, Rob Refsnyder may not make it on the team through the end of this season, Luke Raley under club control through his age 33 season after 2028, Dom Canzone is also under control through 2028 when he will be only 30. On the farm…Laz Montes has now played exactly 64 games at the AA level in both 2025 and 2026, and has shown some improvement in the second stint (14 HR, 39 RBI in 2025 to 20 HR, 54 RBI in 2026), but he’s still maxing out at a .237 average at the level. Jonny Farmelo has struggled to stay healthy and isn’t exactly dominating at Everett the way a first round pick should. Yorger Bautista is only hitting .226 in Arizona rookie ball. If you compare those top 10 OF prospects to the Mariners top 10 SS prospects (Celesten .308/.409/.880 in Everett and Becker .271/.432/.890 in Arizona); the shortstops have the current edge in performance. This may point Seattle’s draft interests more towards reinforcing CF than SS early on.
In terms of Hull, specifically…I wonder if you don’t try to go more of the Colt Emerson route, which would be to target the bat-to-ball player, but then to add power during the development. Also like Emerson…Hull seems to have very high intangibles including leadership.
#4.129 – RHP, Georgia, Dylan Vigue
There was a time in the middle of the college season that I had Vigue in every mock draft I did. He felt like a fourth round steal. But then he really seemed to scuffle over his last 5-6 regular season starts. In his start in the CWS Super Regionals vs Texas; I thought Vigue looked back to the form I saw from him at the beginning of the season. The foundation here is the sinker/sweeper combination which Vigue threw roughly 95% of the time this year. There are additional offerings in a cutter and a change that we really need to see more progress on.
#5.162 – C, Cal Poly, Ryan Tayman
Catcher is one of the positions I always try to include in the top six rounds of my mock drafts. Tayman is a nicely balanced hitter/defender at the backstop who can hit, hit for power, and throw. Down on the farm; Seattle’s top-ranked catching prospect, Luke Stevenson has regressed a bit in Everett after a hot start to his pro career in Modesto in 2025 where he hit .280/.460/.860 in 22 games. At Everett his line has dropped to .225/.410/.789 with only four homeruns in 50 games. There are no other catchers in the Mariners’ top 30 prospects. In previous mocks, I’ve had Seattle draft Texas catcher Carson Tinney in the second round. I don’t think that’s a crazy idea. Especially after Tinney was recently named the 2026 Division I catching Gold Glove winner. Tayman is a capable fallback plan.
Tayman hit .357/.447/1.119 with 18 HR for the year.
#6.191 – RHP, St Joseph’s, Christian Coppola
Coppola is a reliever by recent history, but I’m wondering/hoping if he doesn’t in fact have starter stuff. Either way, I think he is predominantly underrated on media big boards. I’m forcing his pick early to secure his services. Depending on the innings amount used to determine qualifiers; Coppola can be seen as the #1 pitcher in the country by SO/9. He had 16.6 to go with a 1.69 ERA, 0.884 WHIP, and 2.9 BB/9.
#7.220 – LHP, Texas, Luke Harrison
Harrison is a bit of a forced pick. I’m always looking for lefthanded pitching, especially starters, and Harrison looked pretty solid in his recent CWS start. Listed 6’2″/220lbs, Harrison has a season line of 4.10 ERA, 1.260 WHIP, 10.8 SO/9, 3.8 BB/9. He definitely looks like a guy that needs a season or two at Gas Camp to maybe build him up to a bit more velo.
#8.250 – OF, Pittsburgh, Lorenzo Carrier
Carrier continues to be in my mock since previous editions. Probably my favorite RHB in the college class. Being a senior-sign guy at 23 y/o is the only reason, I think, that he is available this late.
#9.280 – SS, HS, Christian Doty
From my favorite college RHB to my favorite prep RHB…Doty has probably my favorite swing and barrel rate of all the prep players. His future defensive position is probably a fair question, but that has also come in to play for previous Mariner prep shortstop picks like Cole Young and Colt Emerson that were drafted in the first round. That is one of the least important questions. If the bat plays; you will find a spot for him.
#10.310 – RHP, Oregon State, Isaac Yeager
For the longest time; it felt like the Mariners didn’t take drafting relievers seriously. That seemed to change, I want to say, two years ago when they really made a focused effort to draft quite a few high-value relievers. Some of those guys were quickly flipped in trades for MLB talent, but some (Charlie Beilenson and Brock Moore) are already at AA, which Seattle has frequently used as the true measuring stick for pitchers being MLB-ready (rather than AAA). I like this draft to, again, selectively take a couple fast-moving relief arms.
Yeager is a Seattle native, and I’d love for him to make his pro journey come through Everett, Tacoma, and Seattle. He’s a legit prospect coming from a pitching program in Oregon State that has ties to the Seattle player development program in the Beavers’ head coach Mitch Canham, the 2019 manager of the Arkansas Travelers. Yeager had a 2.04 ERA, 0.908 WHIP, 11.1 SO/9, 2.5 BB/9.
This is what this half of the mock looked like in the simulator. Glitch in the program lists the Christian Doty pick as Tyler Albanese, but note the signing bonus coincides more with a prep player’s bonus.

#11.340 – SS, Nebraska, Dylan Carey
Carey would be tremendous value at this round. He hit .353/.428/1.050 with 15 HR and was a finalist for the college Gold Glove at shortstop.
#12.370 – 1B, Baylor, Tyce Armstrong
Armstrong is one of the best righthanded power bats in the draft. He’s 6’4″/228lbs and hit .338/.453/1.211 with 24 HR in 56 games. He’ll turn 23 the week before the draft, which is the only reason he might fall this far.
#13.400 – C, Notre Dame, Mark Quatrani
Quatrani had a very strong year after transferring from Cornell to Notre Dame before this season. He hit .376/.457/1.100 with 15 HR. He doesn’t have the strongest throwing arm, but he’s a very good receiver.
#14.430 – RHP, LaTech, Declan Dahl
It’s tough to find depth starting pitching in the draft, so you kind of need to dig in crates of the smaller schools. Dahl is 6’3″/195lbs and pitched to a 3.54 ERA, 1.180 WHIP, 11.3 SO/9, and 2.5 BB/9.
#15.460 – LHP, Bowling Green, Ethan Stade
Stade would be a nice little upside play as a lefty pitcher. He had a 4.36 ERA, 1.141 WHIP, 14.5 SO/9, 2.8 BB/9. As of now his fastball is topping out at 92mph, but if we can add even 3mph to that; he could be at least a bullpen piece. I’m sort of picturing Brandyn Garcia who the M’s drafted in the 11th round in 2023 out of Texas A&M.
#16.490 – RHP, Coastal Carolina, Darin Horn
Horn is an overaged reliever without much velocity. So why draft him at all? The guy misses bats. He averaged 12.4 SO/9 with a 3.21 ERA, 1.262 WHIP, and 3.2 BB/9. If everything goes right; he might be Cooper Criswell.
#17.520 – RHP, Clemson, Hayden Simmerson
I really wanted to draft Taiwanese RHP Jui Chieh Lin with this pick, but I’m not really clear on his eligibility. He is currently pitching in the MLB Draft League but I don’t know if that is a de facto indication of draft eligibility.
I take Simmerson here instead, who may be poor man’s Cal Randall. He had a 3.62 ERA, 0.897 WHIP, 12.8 SO/9, 3.1 BB/9 in 32.1 relief innings for Clemson.
#18.550 – LF, Northeastern, Harrison Feinberg
I had a few outfielders that I liked at this pick, but I went with Feinberg because of how hard he plays on defense. This guy is a gamer. He hit .331/.440/1.037 with 16 HR and 42 SB for the year. He doesn’t even particularly read as that fast of a runner…but he seems to have that Josh Naylor feel for when to run.
#19.580 – RHP, Olathe West HS, Max Hamilton
Hamilton was the most last-minute addition to this mock draft. When I ran the simulator for the first ten rounds; using their pre-assigned bonus amounts; I had a surplus of $524,000 for all ten rounds. And that doesn’t factor that the Mariners may actually be able to get agreements for less than the simulator bonus amounts. If I can save another $326k on one or more picks; add that to my surplus, and add another $150k, which all picks in rounds 11-20 are allowed without penalty; I can offer another prep player a $1million signing bonus.
Hamilton is a bit of a two-way-player, but I like him on the mound. Listed 6’2″/208lbs, and there is something about his mechanics and his stuff that really speak to me.
#20.610 – 3B, Toledo, Troy Sudbrook
I like to backup my prep players in my mocks with college players at the same positions. It gives us a more developed option with which we can staff our farm teams throughout the summer as we release underdeveloping players from previous years’ drafts. Sudbrook hit .373/.467/1.132 with 11 HR, 32 doubles, and 13 SB. And he’s a solid defender at third.
Sudbrook has announced a commitment to Clemson in the transfer portal, but he will turn 23 y/o during the 2027 college season, so getting drafted may be the only thing he needs to stop him from setting foot on campus.
If Seattle can get Bolemon signed for closer to $3.5mill, and/or if they don’t manage to sign Doty in the 9th round…they will have enough signing bonus surplus to go after a prep player like Hamilton anywhere on day three of the draft and give him a seven-figure bonus. This may be the team’s last opportunity to draft prep players, so it makes so much sense to really try to stock up now.
