We’re just over three weeks away from the 2025 MLB Draft, and things are speeding up in the process. The finals of the College World Series start tomorrow, and we’ve seen some high pressure, high stakes performances from many names relevant to this year’s draft. Multiple summer leagues are underway including the MLB Draft League and the Cape Cod League. And last week we had the fifth annual MLB Draft Combine. We’re getting lots of new, more specific data points on a lot of players hoping to hear their names called in July.
This new info is, perhaps, pointing us towards a clearer picture of the broader overall draftboard. What are the tiers of different player profiles. Who are the guys that are rising. Who are the guys at the back of the draft that have differentiated themselves from guys that will probably go undrafted.
In my previous mock draft for the Mariners; I speculated on a draft strategy wherein Seattle would look to, effectively, trade their 2025 first round pick at #3 overall to the 2026 draft where it would become the #4 overall pick, in what looks to be a stronger class at the top of the draft. I knew when I wrote that mock this idea was unlikely…nobody in MLB ever does this. I still think it would be a bold, innovative, and smart move. But it’s like a 1% chance that it happens.
So what would be the second-best draft strategy in a weak top-end draft class?? I think it would be to hyper-focus on prep players. The guys that we don’t have as clear of a picture on their future values, but which could mean higher upside (while, naturally, also having the risk of lower upside). While seeking that upside, I think it’s simultaneously important to get multiple bites at that apple, which means looking for an underslot signer for that #3 pick (and maybe a couple select points on day two of the draft), which can then give you surplus bonus money to offer to players that fall to later picks.
Something that the media has come to pretty consensus agreement on for this draft class is that there is a pretty strong group of high school shortstops. This group includes to some degree, and some variance in likelihood that they can stick at short, players like: Ethan Holliday, Eli Willits, Billy Carlson, Jojo Parker, Steele Hall, and Daniel Pierce. These are all players ranked in the top 20 overall on most big boards.
Holliday is widely considered to be the likely #1 pick going to the Washington Nationals. We won’t look much at him.
Willits is the #5 player on the MLB board. Listed 6’1″/180lbs and a switch-hitter. Willits is a young player for the class (which some teams prefer) as he won’t turn 18 until December.
Carlson is #7 on the MLB board. Listed 6’1″/185lbs and a righthanded hitter. Carlson will turn 19 about two weeks after the draft. He might be the best pure defender amongst these early candidates.
Parker is #10 on the MLB board. Listed 6’2″/200lbs and hitting lefthanded. Parker probably has the best hit-tool amongst this group, while probably having the least likelihood of sticking at short. He turns 19 in August. Of this group, Parker is the one that two separate media sources have independently connected to Seattle as a potential underslot signee.
Hall is the #13 player on the MLB board. Listed 6’0″/180lbs and hitting righty. Hall is another younger player that will turn 18 about ten days after the draft. Interestingly, Hall and Billy Carlson are both committed to the University of Tennessee. It’s unlikely both make it to Knoxville.
Pierce is the #18 overall on teh MLB board. Listed 6’0″/185lbs and hitting righthanded. He will turn 19 in August.
Is there a combination of present grade, future grade, and signing bonus figure from this group that puts one of these guys ahead of the others? And, really, part of the equation is actually: “is it better to draft a college player at/near/above bonus slot at #3, or would it be better to get an underslot player with more upside that then also allows you to get another upside player later on?” Basically a question of, “can you get two for one?”
In this particular draft class, I think they should do the latter. Let’s go for the 2×1.
In my opinion, the two guys to focus on in this scenario are Billy Carlson and Jojo Parker. This basically represents the best defender of the group and the best hitter of the group. In my first mock draft in May, I actually was going with Carlson as I just loved his glove so much. In theory, Seattle has two pretty strong shortstop candidates already coming through the system in Colt Emerson and Felnin Celesten. We don’t, necessarily, HAVE to keep a guy at shortstop.
So, in this mock, I’m pivoting to take the better hitter, who also happens to be the guy that has some buzz surrounding Seattle interest. There’s also the fact that Parker was a member of the 2024 East Coast Pro all star team of players from the states of Mississippi, Alabama, Arkansas, etc that were chosen by Mariner scouts and played under the name “Mariners”. There is some documented connection between Seattle and Jojo (and Jojo’s twin brother, Jacob).
#1.3 – SS, Purvis HS, Jojo Parker
While the hit-tool is clearly the headliner here; as I’ve dug in deeper to Parker I think his power and his glove are underrated. No, I don’t think he sticks at shortstop, but I do think he sticks on the dirt. His fielding actions are smooth and efficient. I think his move off shortstop will be dictated more by his range than his literally fielding. His arm looks decent. I think he’s a future third baseman. And that’s where the underrated power will come into play. I think his power is coming along very nicely and he will have enough power for 3B. He might end up similar to another player that has recently been in the news: Rafael Devers.
Now comes the business end of this selection. As a guy being projected as the #10 player in this class; if you draft him at #3, you’re doing so (in part) to save some money. The #3 pick holds a bonus slot value of $9.5million. The bonus slot value of, say, the #10 pick is $6.2million. The middle point between those two is $7.85million. If you sign Parker for, roughly, $8million, that $1.5million savings will come in extremely useful on later picks. For those that question the plausibility of underslotting a high school player at #3…Max Clark was drafted at #3 overall in 2023 and signed for about $600k underslot. The same draft, Blake Mitchell signed for ~$1.08million underslot at pick #8. Kumar Rocker drafted out of college in 2022 at pick #3 signed for $2.39mill underslot.
#1.35c – 3B/OF, Oaks Christian HS, Quentin Young
The second big adjustment in this mock draft is that my intended/previous target at #35, RHP Patrick Forbes, is now going to be off the board after his performance in the CWS. But, with the bonus savings at #3, this pick can now be another prep player.
I love 2B/OF Sean Gamble. What an impressive, mature profile. He kind of reminds me of Corbin Carroll.
I love local product Xavier Neyens, but as a lefthanded hitter with future 3B in his projection; he’s probably redundant after drafting Parker.
And there’s potentially a handful of prep pitchers that profile similar to 2024 draftee Ryan Sloan that might fit here: LHP Jack Bauer, RHP Aaron Watson, RHP Landon Harmon, LHP Johnny Slawinski. High school arms are historically the riskiest draft demographic, and Seattle historically can find/develop interesting, future-MLB arms from college pitchers in the midrounds of the draft.
I’m going with Quentin Young here because he’s different than what we’ve ever seen the M’s draft out of high school. He’s a power-first righthanded hitter when Seattle has almost always drafted hit-first, lefthanded guys.
Young is an MLB bloodline guy with two uncles that played in Delmon and Dmitri Young. He’s already 6’6″/225lbs with grown-man exit velocities touching 115mph at this week’s Combine. He’s got pretty surprising fluidity playing the infield at that size, so he might stick there. But he’s also got enough speed when underway that he might make a decent outfielder.
Quentin is ranked #33 overall on the MLB board, so this isn’t a reach or a fall. And then it comes down to giving him enough bonus to sign him away from college commitment to LSU. The slot value for #35 is $2.75mill. With most of the savings from the #3 pick; we could get Young signed for $4mill, which equates to about the #21 overall pick, aka first round money.
#2.57 – LHP, Iowa, Cade Obermueller
If there’s a second category of player that the 2025 draft looks especially strong in; it’s probably lefthanded pitching. And that is something that Seattle is woefully short on in their farm and major league team. I don’t know why they treat LHP the way that they do. I speculate they have data that points to RHP being stronger performers in TMobile Park, but who knows.
There’s also something interesting going on this year with pitchers that are shorter in stature. There are an unusually high number of starting pitchers that are right about 6’0″ tall. Liam Doyle is listed 6’2″ but I don’t believe that at all. JB Middleton is listed 6’0″, Gage Wood is listed 6’0″, Obermueller is listed 6’0″, JD Thompson is listed 6’0″, Brian Curley is listed 5’10”, Zane Taylor is listed 6’0″. Could there be a Spencer Strider in that group?
Obermueller might be merging these two factions. For the year, he posted a 3.02 ERA, 1.128 WHIP, 12.6 SO/9, 3.5 BB/9. Compare that to likely top five pick Jamie Arnold: 2.98 ERA, 1.063 WHIP, 12.6 SO/9, 2.9 BB/9. And then note the similar pitching mechanics/release heights of these two players. These are surprisingly similar profiles, but with a huge discount on Cade.
#3.91 – OF, George Mason, James Quinn-Irons
There’s a nice little pocket of players in this class that have imposing size, nice power, sneaky good gloves, and bonus basestealing in the outfield. I like JQI the best of that grouping. Listed 6’5″/230lbs and posting a 2025 line of: .419/.523/1.258, with 16 HR, 42 XBH, 39 BB, 46 SO.
#4.122 – RHP, Tulane, Michael Lombardi
After losing out on Patrick Forbes, I think I’ve found a similar profile in Lombardi. Forbes was formerly a two-way player that is now pitching-only for the last two years. Lombardi was still playing two-ways this year with games as CF, 2B, 1B and P (primarily CF).
As a pitcher, Lombardi had 23 appearances, including 6 games started. I don’t have splits for how his numbers broke down starter vs reliever, but his overall performance went: 2.14 ERA, 0.976 WHIP, 15.6 SO/9, 4.5 BB/9 across 42 innings. The hope is that he can start and that, with focus on pitching, he can tighten up his control.
#5.152 – C, Wright State, Boston Smith
I think I’ve bounced back and forth in my respective mocks on how early to draft Smith. I’m steering into my hitting metric this time, and giving him closer to the value that my stat suggests. The lefty-hitting catcher with power is just too valuable.
#6.182 – RHP, UNCW, Zane Taylor
Similar to Boston Smith, with Taylor I’m steering into my pitching metric more this time. Taylor is another in that list of shorter starting pitchers that we’re dreaming on a Spencer Strider. On the year, Taylor went 1.98 ERA, 0.763 WHIP, 9.9 SO/9, 1.0 BB/9. At the combine he posted one of the top fastball velo’s at 97.7mph.
#7.212 – RHP, Abilene Christian, Dominick Reid
Reid I had in my previous mock. 6’3″/201lbs and a former transfer from Oklahoma State. Reid’s line was 3.26 ERA, 1.109 WHIP, 11.4 SO/9, 2.8 BB/9 in 15 starts this year. And then, at the Combine this week, Reid popped as one of the top performers in multiple pitch movement measurements. There’s some intriguing clay to mold here.
#8.242 – 3B, Cincinnati, Kerrington Cross
Most likely a senior sign, Cross has tremendous intangibles, and he’s no slouch in the on-field performance: .396/.526/1.173, 12 HR, 50 BB, 35 SO, 15 SB.
#9.272 – RHP, Baylor, Gabe Craig
Craig is the #1 relief pitcher in my metric, and he has some postseason awards on his resume that may make this way too late to get him. But at 6’5″/209lbs, with a 0.56 ERA, 0.500 WHIP, 14.3 SO/9, 0.8 BB/9 and 10 saves this could be a fast-mover in a system that needs more in-house pitching.
#10.302 – OF, Dallas Baptist, Nathan Humphreys
Humphreys first caught my eye with his glove. He’s got legit centerfield skills. And then his offensive line wasn’t too shabby either. He hit .353/.457/1.135 with 17 HR, 38 BB, 38 SO, and 21 SB.
#11.332 – LHP, Florida, Pierce Coppola
Coppola is a carryover from previous mocks, and we’re just trying to find the sweet spot between his present value where he’s a frequently-injured starting pitcher, his really strong performance when he HAS pitched, and the fact that he might be discounted due to his senior status (and injury history). But if you pick the right round, this could be insane value for an SEC starter.
#12.362 – RF, Kent State, Jake Casey
Casey is the son of Sean, the longtime MLB player, and he has put together a very solid college career in his own right. At 6’2″/190lbs, Sean hit .356/.500/1.236 with 17 HR, 20 SB last year. And he’s got an above-average outfield arm.
#13.392 – RHP, Vanderbilt, Sawyer Hawks
It felt like the Mariners tried to draft a handful of quick-moving, relief pitchers in the 2024 Draft. That effort seemed to sidetrack this year with injuries and/or underperformance. But it still could be a useful strategy going forward. Hawks is an Air Force Academy transfer listed 6’4″/215lbs. In 2025 he had a 1.60 ERA, 0.800 WHIP, 11.8 SO/9, 2.2 BB/9 and 8 saves in 18 appearances out of the Vandy bullpen. His fastball has been up to 95mph.
#14.422 – 1B, Austin Peay, Ray Velazquez
There were a bunch of interesting bats on this Austin Peay roster, but I came away having Velazquez as the highest on my hitting metric. At 6’1″/212lbs he hit .364/.479/1.207 with 18 HR, 32 BB, 32 SO in the college season, and he’s continued swinging it well across the first five games he’s played on the Cape where he’s sitting at a .389 average.
#15.452 – RHP, Coastal Carolina, Ryan Lynch
Lynch is the local product from Monroe, WA that has made his way all the way to the College World Series finals tomorrow. A pure reliever at 6’4″/234lbs, he has a 0.58 ERA, 1.032 WHIP, 10.2 SO/9, 2.9 BB/9 and 9 saves in 27 appearances.
#16.482 – 2B, UConn, Ryan Daniels
When doing a Mariner mock draft, I can’t help but think of it similarly to putting together a roster. After all, most of these guys will end up becoming the bulk of the low-A Modesto lineup later this summer. You kind of need a variety of guys so that you have most positions covered.
Daniels was one of the better second base options from my hitting metric. He posted a line of .365/.476/1.220 this year with 18 HR, 40 BB, 41 SO, and 10 SB for the Huskies.
#17.512 – LHP, UCSB, Hudson Barrett
Barrett was one of my most recent discoveries just in the last week after popping in the Combine with some of the higher-ranking pitch movement statistics on his secondary pitches. At 6’5″/225lbs, Hudson is a prototypical pitcher build, and his rate stats of 1.93 ERA, 0.643 WHIP, 9.6 SO/9 are solid. There is some question mark as to why he only threw 4.2 innings during the college season in three starts as an “opener”. In his summer league more recently, Barrett threw 4.0 innings of shutout ball.
#18.542 – C, Georgia State, Colin Hynek
I generally like to have two catchers in every mock. It’s too much of a specialty position to not get a couple. Hynek is a 6’1″/200lb backstop with an underwhelming .230/.396/.982 slash, but 18 HR and a solid catch and throw defensive profile.
#19.572 – RHP, Grove City CC, David Leslie
Leslie is another recent discovery after a strong performance in his first appearance out of the bullpen for his MLB Draft League team. Listed 6’3″/185lbs, his JUCO season line went: 2.05 ERA, 0.938 WHIP, 10.13 SO/9.
#20.602 – LF, Southern, Cardell Thibodeaux
Thibodeaux is quietly one of the best pure hitters in the country. He hit .439/.544/1.391 with 18 HR, 39 BB, 27 SO, and 24 SB during the college regular season, and he’s recently posting near-identical numbers in the Draft league at .423/.545/1.199 with 1 HR, 7 BB, 4 SO in 7 games so far. The downside is that he’s only 5’8″/175lbs and really only has one year of strong performance, and it came in the lower level Southwestern Athletic Conference.
