Mariners Swap a Ford for a Ferrer(i)

On Saturday afternoon, the Mariners traded catching prospect Harry Ford to the Nationals in exchange for Jose A. Ferrer; the Mariners also sent right-handed pitcher Isaac Lyon, their 10th-round pick from this year’s draft, to Washington. Robert Murray of FanSided had the news first.

This is a trade that raises a few eyebrows. While Ford moved through the minor leagues slowly by modern standards, he’s been a consensus Top 100 prospect for nearly three years now. It’s a little jarring to see someone of that caliber dealt for a reliever, particularly one with pedestrian surface-level numbers and good but not sterling peripherals. My initial reaction was that Seattle sold low on Ford, though further review has changed my thinking a little. Let’s dive in.

The Mariners’ side of this takes a little more nuance to work through, so we’ll start with their situation. Ford is a good, if not great prospect. He’s been on our Top 100 list for a couple seasons now on the strength of a well-rounded game, finishing the 2025 season ranked 43rd overall as a 50 FV. He can hit a little bit, there’s average power that he’s learning to tap into, and he’s growing into a reliable, if unspectacular defender behind the plate. There isn’t much star potential here, and I’ll say more on why that is in a bit, but he does project as a regular.

But Ford was also as blocked as any prospect in the minors, stuck behind MVP runner up Cal Raleigh. Raleigh is durable, excellent, and thoroughly entrenched after inking a six-year extension this past March. The Mariners had experimented with Ford in the outfield to see if they could find something else for him to do, as it’s been clear for a while now that his future would not be behind the plate in Seattle. He’s been an obvious trade candidate for at least a year, and the only surprise is that it took so long for the M’s to move him. They’ve reportedly been shopping him for impact relievers elsewhere; frankly, this is a swap that would have made a ton of sense four months ago, when Ford was just as blocked and the Mariners could have used more relief depth in front of Andrés Muñoz and Matt Brash for their playoff push. Oh well, not like it bit them in the butt during October.

So, trading Ford makes sense. But for Ferrer? A guy with a 4.36 career ERA? Don’t they have holes around the infield, ones they may need to fill via trade since it seems like their off-season budget is pretty modest? What gives?

As readers likely know, Ferrer’s numbers under the hood are much better than his ERA. His FIP over the last two years is under 3.00, thanks to tiny walk and home run rates. He’s also one of the league’s foremost groundball generators. His groundball rate is just over 60% for his career, and of the pitchers who threw at least 50 innings in 2025, only José Soriano, Jhoan Duran, and Tim Hill topped Ferrer’s 62.6% mark. As you’d expect, it’s really hard to drive the ball against him, and he only allowed five long balls in 76.1 innings of work in 2025. He takes full advantage of his ability to dampen damage on contact, pounding the zone to the tune of a 2.21 career BB/9 rate and an in-zone pitch rate of nearly 60% (roughly the 90th percentile for the league).

And of course, the Mariners aren’t just acquiring those numbers. They’re trading for the chance to unlock more, and you can see compelling paths forward here.

This season, Ferrer mostly just pounded the zone with his sinker while mixing in a changeup about 20% of the time and a slider once or twice an outing. His sinker is quite good, as it sits in the upper 90s, touches 100, and features plus tail. It’s a quick and reliable way for him to generate outs, and you can see why he leans on it. But like most pitchers who spam the fastball, there’s an argument for a usage adjustment here. The changeup performed very well in 2025, generating big whiff and chase rates, and hitters didn’t do much with it even on contact. He could probably stand to use it more.

The real path forward may be the slider, though. Ferrer’s sits in the low 90s and has tight, two-plane movement, not quite cutterish but in the neighborhood. His command of it isn’t great, generally in the dirt to the glove side, but whether it’s because guys don’t expect the Spanish Inquisition or they’re just not seeing his spin very well, opponents did absolutely nothing with it and whiffed more than half the times they swung. The Mariners have had a lot of success getting fastball-heavy arms to diversify their arsenal — Logan Gilbert and Bryce Miller are two obvious examples — and it would come as no surprise if they have Ferrer lean on the bender a lot more going forward.

Put everything together, and you can imagine why Seattle sees Ferrer as an impact reliever, the kind worth parting with a top prospect for. Sources from around the game like Ferrer as an upside play. He throws hard, he pounds the zone, he has three pitches that flash plus, and there’s a relatively straightforward adjustment that could unlock more. With four years of team control left, he’s not even expensive. He lengthens the bullpen and gives the Mariners a left-handed weapon of a magnitude they didn’t have last season. There’s always risk in acquiring relief pitching, but this looks like a safe way to add 1-1.5 WAR to the bullpen, and with his skills, a nutty, sub-2.00 ERA season is not outside the realm of possibility.

On Washington’s side, this also makes plenty of sense. Ferrer’s a tough guy to lose, but good relievers are a luxury on a rebuilding club and swapping bullpen arms for bats with everyday upside is a sound idea. That’s especially true behind the plate. Nationals catchers produced -1.4 WAR in 2025, last in the majors, and were awful on both sides of the ball. Led mostly by Riley Adams and Keibert Ruiz, the club’s backstops hit .225/.270/.322, good for a 65 wRC+ that was 29th in baseball. Thanks in part to Ruiz’s horrible framing numbers (his mark of -5.3 runs prevented was third from the bottom among all catchers, in 65 games no less), Washington’s catchers were also the league’s worst collective on defense as well. Ruiz was once a top prospect, but he’s now 27, has no approach, and is not exactly an asset defensively. It’s time to move on.

Enter Ford. A first round pick in 2021, Ford progressed slowly and steadily toward the big leagues before making his debut in September. His approach has been awesome: He has a very good eye, he recognizes soft stuff out of the hand, and while he doesn’t swing a ton, he reliably turns it loose on pitches he can drive. If you put a ton of stock in swing decisions, this is your guy.

Statistically, all is well. His production has been strikingly consistent, with Ford notching a wRC+ between 125 and 135 at each full-season level. He’s also posted very small deviations in his walk, strikeout, and — aside from 2024, which he spent in a huge, homer-suppressing yard — ISO numbers, all of which were encouraging. If you value consistent minor league production, this is your guy.

Scouts and evaluators are not universally sold on Ford’s ability to translate that production to the big leagues, though. His bat speed is average and he’s periodically struggled getting his bat to fastballs up in the zone. In his most recent prospect write-up, Eric covered an adjustment Ford made with his feet and timing that seems to have helped this season, but obviously the big leagues will provide a different stress test. I see an average bat with a chance to grow into average game power, but there are scouts who would take the under on both.

Ford’s defensive growth has mirrored his ascent through the minors. His framing has improved but is still fringy, and he may benefit from an ABS assist (though he was actually pretty bad at challenging pitches this season). He shines more in spots where his athleticism takes center stage. He’s quick on plays where the ball is tapped out in front of the plate, and he’s going to catch his share of baserunners. He has an above-average arm, his throwing accuracy has improved, and he caught nearly 25% of would-be-thieves in 2025. Early-career reports questioned whether he had too much trouble simply catching the ball, but his passed-ball figures have plummeted since 2023. I’m projecting an average defender, though again, there are evaluators who will take the under.

It all adds up to a 50 FV report, albeit one where there isn’t a lot of wiggle room if one of the tools doesn’t reach its projection or Ford’s approach buckles against better stuff. In truth, part of that projection is a reflection of the state of catching throughout the league; the bar for being an average regular isn’t very high right now. Still, if he’s average on both sides of the ball, that’s a good player, and he’s the kind of risk Washington should be taking at this stage. Ford could be part of the next good Nationals team, and even if he falls a little short of where we have him here, he’s likely steady enough to be a real upgrade over what they’ve trotted out in recent seasons.

Let’s quickly touch on the other player in the deal. Lyon, the son of former big leaguer Brandon Lyon, signed for nearly $200,000 this summer. He’s a good strike thrower with a bad fastball, a slider and change that flash average, and a delivery with some deception in it. He sat in the low 90s in short starts with Low-A Modesto, and could have another gear as he fills out. He projects as an up-down type and has a low-leverage relief ceiling if he can find a way to throw harder in shorter stints.

One other thing to note: With Ford now in Washington, Seattle will be in the market for a backup catcher. The club is reportedly open to a reunion with Mitch Garver, who hit 24 homers amidst otherwise disappointing production over the past two years as the club’s primary backup catcher; he also started at DH 22 times this season. While Raleigh plays nearly every day, he does DH fairly often, so whoever Seattle signs will probably start about 25% of the time behind the plate.

Ultimately, the deal helps both parties, and one exec I spoke with called it a “win win” move. The more I look at Ferrer, the more he seems like a reliever with another gear, a guy with closer stuff who is a plenty good fit for Seattle’s bullpen as is. Still, I think Washington did well here, getting a high-floor position player at an area of desperate need. The Paul Toboni era is here now, and Nationals fans should be enthused about his first big trade as president of baseball operations with the club.
