The Seattle Mariners ended 2017 with the worst farm system in Major League Baseball. They started 2018 the same way.

While they’re still rank at or near the bottom of the league in organizational talent, the club’s collection is growing.

Since the 2017 MLB Draft, the Mariners have acquired Evan White, Sam Carlson, Julio Rodriguez, Juan Querecuto, Noelvi Marte and Logan Gilbert, among others. It’s not what I’d call flipping the farm system on end, but for a little over a year it’s a solid set of additions that gives the club some foundation to start truly rebuilding the system.

The lone significant departure in the last 13 months is Tyler O’Neill, who was traded for the American League’s 12th-best starting pitcher this season, left-hander Marco Gonzales.

Here’s the Top 40, which includes a handful of international signings from the classes of 2017 and 2018, as well as draftees from both classes.

NOTE: Prospects are evaluated and ranked on upside, risk & probability, future role and performance. Many will wonder why a hitter in Double-A that’s batting .310 with a .400 OBP is ranked so low when players with significantly lesser production are ranked higher. There could be several reasons for that, but a good place to start is age vs. level, then perhaps positional value and projection. If the .310/.400 bat is 26, hits for no power and has no real position on the field, perhaps his ceiling is severely limited. Just saying.

Some roles just aren’t that valuable. I’d rather a 3% chance at an everyday position player or mid-rotation starting pitcher, for example, than a 60% chance of a middle reliever, which is why you’ll see many others ranking many of the Mariners’ relievers in Double-A and Advanced-A a lot higher than I do.

Unless it’s a potential closer — which means a high-leverage, Alex ColomeEdwin Diaz role is apparent at present — it’s a middle reliever profile. That’s literally Nick Vincent. That’s literally Chasen Bradford. Which is literally talent clubs can get for nearly free every year. Vincent cost almost nothing (cash) to acquire a few years ago. Bradford cost literally nothing beyond his minimum salary prior to this season.

Give me another lottery ticket, instead, thank you.

    Thanks again for some great content.

    Interesting stuff. Looking at this from an age bucket perspective 21 of the 40 are 21 years of age or younger so the org could see some nice buildup in talent so long as those youngsters continue to develop.

    26: 2
    25: 4
    24: 5
    23: 3
    22: 5
    21: 8
    20: 2
    19: 2
    18: 3
    17: 5
    16: 1

    More young players who are 21 or younger who missed the list but are noteworthy: Freuddy Batista, Daniel Santos, Igor Januario, Jesus Ozoria, Juan Mercedes, Nolan Hoffman, Jorge Benitez, Matthew Willrodt, Tyler Suellentrop, Cesar Trejo, Jepherson Garcia, Blake Townsend, Dayeison Arias, Max Roberts, Ivan Fortunato, Ryne Ogren, Greifer Andrade, & Jing-Yu Chang.

    Ryan Costello, Jack Larsen, & Joey Curletta are surprise misses in my book but two of them are likely limited to 1B defensively in the bigs. I also am really high on Jamal Wade but he is a reliever.

    Since Marte’s deal was a relative bargain & only one more international signee has been reported for a bonus of 300k or more (that one at 300k) it appears the club has the money to make a run at another big prospect or bonus money to trade as sweetener for a bigger deal.

    That’s a pretty terrible collection of prospects. At this point, no one should be super confident that Kyle Lewis ever contributes. After that, you have a bunch of 16-18 year olds that are essentially unknowns. On Sickels system, no As and probably no B level prospects either.

    Vogelbach at 15 explains to me why no trade activity for this guy.

    So should we be excited about Noelvi Marte? At 16 he seems a long way off, but he ranks here higher than the M’s last two first round picks.

    Thank you for this. I’ve been waiting for it oh so long!
