The Mariners and top shortstop prospect Colt Emerson are in agreement on an eight-year contract extension, according to a report from Robert Murray of FanSided. The deal guarantees Emerson $95MM and includes a club option for a ninth season. That guarantee is a record for a player who has not yet made his MLB debut. The deal also includes a no-trade clause for the ACES client and can max out at over $130MM after incentives. According to Ryan Divish of The Seattle Times, the deal is pending a physical. Jeff Passan of ESPN reports that the deal is expected to be done this afternoon and that Emerson will remain at Triple-A for now.
Emerson, 20, beats the previous record guarantee for a player without any MLB service time (previously held by Jackson Chourio) by $13MM. It’s not hard to see why the Mariners are giving him a guarantee that nearly reaches nine-figures before even seeing him take a single MLB at-bat, however. The youngster is a consensus top-10 prospect in the sport and rocketed through the minors last year. After starting 2025 at the High-A level, he walked at an excellent 13.1% clip and swatted 32 extra-base hits in just 90 games. That forced the issue enough to earn him a promotion to the upper minors and, across 40 games between Double-A Arkansas and Triple-A Tacoma, Emerson slashed .293/.383/.470 in 188 plate appearances. That would be an impressive slash line for any player, but even more so for a 19-year-old who plays quality defense all over the infield.
The Mariners made the decision to let Eugenio Suarez and Jorge Polanco depart in free agency over the offseason, and Emerson’s emergence was surely part of that calculus. For now, the club has an infield mix that appears full on paper, with J.P. Crawford at shortstop, Cole Young at second base, and the recently-acquired Brendan Donovan at third base. There’s plenty of room for Emerson to get into the mix in both the short- and long-term, however. Crawford is currently on the injured list with a bout of shoulder inflammation. He could return relatively quickly from that injury Emerson could theoretically slide into the starting lineup as soon as tonight, if not for Seattle’s plans to keep him at Triple-A for now. Crawford is also slated to hit free agency after the 2026 season, which opens up the shortstop job for Emerson long-term.
Even when Crawford returns to the infield, it should still be feasible to find Emerson playing time. Young is a former top prospect himself and is well-regarded by the Mariners, but he’s ultimately unproven at the big league level and could open up playing time at the keystone if he struggles or sit against tough lefties. More importantly, Donovan was acquired in no small part thanks to his elite versatility. The super-utility man is primarily an infield but has plenty of experience on the outfield grass as well. It would not at all be far-fetched for Emerson to take up the regular third base job and bump Donovan to right field, thereby displacing either Dominic Canzone or Luke Raley from the starting lineup.
While a spot could be made for Emerson in the majors, it’s understandable that the club is holding off on promoting him for now. This extension is a big bet on his ability and removes the consideration of service time from the equation, but Emerson’s development must still be considered. While MLB Pipeline notes that his defensive metrics last year suggested he was an above-average defender at short, he has just 111 1/3 innings of work at third base for his career and just 75 at the keystone, so it would be understandable if the team wanted to get him additional looks at those positions before giving him a full-time role in the majors.
As for his offense, Emerson has just nine total games at the Triple-A level and 43 total in the upper minors. That’s not a lot of time afforded for his development, and while some top prospects are able to jump right in at the big league level with minimal minor league experience the Mariners should remember all too well the struggles outfielder Jarred Kelenic faced when he was promoted to the majors after just 51 games in the upper minors (including 30 at Triple-A). The front office surely has no interest in risking Emerson’s development on calling him up before he’s ready, particularly given the fact that Emerson is now slated to receive the fourth-largest guarantee on Seattle’s entire roster behind Julio Rodriguez, Luis Castillo, and Cal Raleigh.
Regardless of when Emerson ultimately reaches the majors, this deal locks up a key piece of Seattle’s core for the future. With Emerson now under club control through the end of the 2034 season, he joins Raleigh, Rodriguez, Josh Naylor, and Young as key players under control through at least 2030. That positional core is complemented by impact pieces like Donovan, star close Andres Munoz, and of course the club’s vaunted starting rotation of Castillo, Logan Gilbert, George Kirby, Bryan Woo, and Bryce Miller. All five of those starters are set to hit free agency between the 2027-28 offseason and the 2029-30 offseason, so perhaps the club’s long-term planning can now focus on the future of the rotation now that key positional assets like Raleigh and Emerson are locked up for the long haul.
Smart move by the M’s. Emerson is going to be a big contributor for a long time.
OR he is going to be a huge bust and drag down the team for a long time. No one knows because he has not proven anything yet.
It’s less than $12M per season for an eight-year contract and will most likely be backloaded with a signing bonus. That’s not going to drag down any big market team.
Are the Mariners are big market team?
*mid
I’m not sure how people deal with everyday life if the cannot tolerate risk.
Magic 8 Ball says ……lol
Most people in everyday life do not have $95M evidently sitting around.
OR he’s going to be an everyday regular.
Hiflew, the price goes up like Anthony’s cost with Boston. They believe in the kid so it’s great all around. The money is more than Campbell but I do understand your concern.
Kudos to the M’s for getting this done! I wish other organizations did the same.
A lot of teams lock up their young talent. You just haven’t been paying attention.. I believe The Cleveland Indians were the first to do it back in chelate 90’s.
True. But teams like the Braves have done so after a year or two of proven production, then extend them through the first few years of free agency. I’m all for taking risk but this seems like an overreaction to fans crying to spend more money. How about extending young pitching…
No strike in future if MLB teams are handing out contracts worth millions to players in the minors and majors!
So do you just call him up?
They probably should and keep the PPI pick in play. Wouldn’t surprise me if he’s better than Cole Young today.
No PPI when there is an extension
I believe he also had to be on the opening day roster, not 5 days after opening day.
Thanks. Forgot about the ext rule prior to the call up.
I wonder what the safeguards are? What if they announce the deal but don’t officially ink it until he’s on the ML roster?
Just has to be called up within the first 2 weeks. He’d be eligible for the pick without an extension if they called him up tomorrow.
according to MLB you’re right, but also a weird throw in that if they are opening day players not within 2 weeks they retain the PPI elligibility, and can be attained with top 3 MVP or CY in a 3 year window. At least that’s how i’m reading it.
below
“Players with little or no MLB service time need to break camp with the team or be called up within two weeks of Opening Day. Then they must spend all or most of the year in the big leagues. Then they must either win their league’s Rookie of the Year award or place in the top three for MVP or Cy Young.
Players who made an Opening Day roster and accrued the service time but didn’t factor in any awards that year retain PPI eligibility. They need to place in the top three for MVP or Cy Young before hitting arbitration. That typically allows for a three-year window.”
Put him at SS. Leave Young at 2B. Trade Crawford.
Great move by Jerry and Co. Now they can focus on extending Gilbert and Woo
And Kirby.
Hard pass, Kirby ain’t it. Great stuff and control but doesn’t have that ace mentality. His starts are dictated almost entirely by if he’s getting barreled or not. And yeah that sounds like a “no duh,” but what I mean is he throws hittable pitches every time out, sometimes they get hit and sometimes they don’t. And when they do get hit, the adjustment is severely lacking.
Lock Woo and Logan for sure.
A no trade clause is ridiculous.
Hopefully this isn’t a pivot because they realized they won’t be able to extend any of Kirby Gilbert or woo but nice I hope he’s as advertised
The Mariners have a Colt in their stable now they hope will be a horse they can ride for a few years.
Roll eye’s
Yessir!!
Hope it works out better than Kingery did for the Phillies.
or Evan White did for… let me check my notes… the Mariners.
That was my first thought.
You don’t even have to leave Seattle for a comparison. Oh how quickly people have forgotten Evan White. Except in this case, with the no trade clause, they won’t even be able to pawn this guy off on the Braves in case it doesn’t work out.
I like it, Emerson looks like the real deal.
Locking down a star for the Mariners. Top prospects are getting paid. Watch Konnor Griffin beat Emerson’s guarantee later today.
I’ll bet against Bob Nutting losing the chance at a draft pick and guaranteeing a huge sum of money.
If Griffin signs an extension, it should definitely be higher. However, I wonder if Emerson just raised the bar higher than the Pirates are willing to pay.
Maybe the bar of pressure to sign him but not meaningfully raising the price of Griffin’s extension. Emerson is a top-end prospect but is guaranteed less then $100M for 8 years. Incentives can raise it, sure, but the original offer the Pirates reportedly made had incentives as well. If anything, the base offer of ~$110M likely won’t raise much higher than $130M if it gets there at all. I think that sounds about right for their price range with incentives that could raise it to $150M or so.
We’ll see.
Colt Emerson and Cooper Pratt just became untradable assets. I don’t know why teams would hamstring themselves like this. Especially Seattle. I guess they don’t remember Evan White
Of course it’s risky, but if he’s as good as advertised it’s a bargain.
Small to mid market teams try to lock their young stars up so the don’t go to the big city in six years. It’s a gamble but if you trust your own scouts opinion, it should pay dividends more often or not. If you don’t trust your scouts, you shouldn’t employ them any longer.
Reds-This is a good point.
Pirates won with McCutcheon and Marte.
Lost with Tabata and Polanco and Hayes.
Maybe either way with Reynolds.
Better to let the young player play in the MLs for at least a year to wait until the newness rubs off and then see what they can actually do.
No scouts are perfect.
It is at best a crap shoot.
And,no,Nutting will not be shelling out this kind of money for Griffin until he proves himself in the ML’s.
Nor should he.
Why is everyone pretending that Evan White and Colt Emerson are comparable? White’s deal was for an unbelievable….wait really….? $4M AAV!
That was locking up a high floor prospect at a steal if he was even an okay regular, who then unfortunately had a horrible injury run. That was a 5th percentile outcome, and having that scare you off from future extensions would be beyond stupid.
For every article published, MLBTR should pre-populate the comment section with the usual crap that the first ten posters invariably feel compelled to share with the universe, because it’s the same damn things every single time that an article is published on this site about some player getting a contract extension or some player getting designated for assignment or some player getting injured while mowing the lawn or moving furniture or changing a flat tire or trying to throw a baseball 110 MPH in a meaningless baseball game with all of the other important things going on in our lives that take our attention away from the thing that really matters, which is writing the longest run-on sentence of the day.
Meanwhile the Angels have Neto and refuse to sign him long term. They’ll end up losing him
Takes two to tango, and if I’m Neto there’s no way I’m attaching myself to that sinking ship
Two of these types of moves today is interesting. I wonder if this trend is going to pick up again.
Unlike pratt, emerson’s been terrific at every level and probly should have made the tm on Opening day…all indications point to a successful career ahead… ss 3b 2b with speed & pop…record contract… thats alotta pressure.. he’ll live up to it..
Emerson is getting 2x the money.
One less year of potential control on the club option too. Differential makes sense.
Surprised the Brewers inked that deal but I think Matt Arnold is one of the best around.
the youth are electing to cash out now before the US dollar collapses entirely
They’d have to sign in another currency if that was what they were concerned about.
Glad to see Seattle paying their young stars. Baseball is more fun when the northwest is relevant. Now do Gilbert and Woo next.
They are well positioned to win AL West through 2030 and at-least another trip to ALCS would mark a successful run for this group of players. But ultimately they need to get to the World Series for the first time in franchise history.
Typically reaction by Mariners fans. Applauding spending money just to spend money. 95m to a guy who hasn’t played one game in the majors…we have a young pitching staff that needs to be shored up and our budget is not unlimited.
Let’s take risk and spend money, but this makes little sense. Let him play a year or two and see if he’s worth extending before arbitration.
The same fans who are cheering may be really sad we committed this early to someone who hasn’t proven anything.
