Below is an analysis of the prospects in the farm system of the Arizona Diamondbacks. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the sixth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

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.

We’re less than a month from the Winter Meetings and the Rule 5 Draft, which means it’s a good time to evaluate every team’s 40-man roster situation. This is the time of year when teams have one final chance to protect Rule 5 eligible players by placing them on the 40-man. Eligibility is determined by a mix of how long a player has been with their parent organization and how young they were when they signed: Players who signed at 18 or younger must be added to the 40-man within five seasons, while everyone else must be added within four. RosterResource monitors Rule 5 eligibility, if you’re curious to see the lay of the land.

During the season, teams can free up roster space by placing an injured player on the 60-day IL. In the offseason, teams don’t get extra slots for injured players, which tends to put pressure on the back of the roster. The Diamondbacks are a good example of how space can tighten quickly, as they’ve currently got six pitchers battling long-term injuries occupying a spot. You may have noticed a flurry of moves immediately following the World Series, with many teams outrighting players off the 40-man in order to make room for all the guys who were on the IL.

Below, I’ve assessed every National League team’s 40-man roster situation (Eric will sort through the American League tomorrow). Some teams, like the Braves, have plenty of roster space, and thus a lot of flexibility in adding whoever they like. Others, like the Cardinals and Marlins, will face some tough choices as they seek to balance protecting interesting prospects with retaining players already on the roster, as well as finding room for prospective additions via trade or free agency. Some clubs don’t have many impact players to add, while others may need to protect a half-dozen or so guys. I’ve tried to identify which players are most likely to be added, which guys on the 40-man are vulnerable to getting lopped off in a roster crunch, and who could be moved in a deal to free up roster space. Let’s dig in. Read the rest of this entry »

Hello, my name is Brendan Gawlowski. I could do the Troy McClure thing and list all of my previous bylines, but I’d prefer to just say that it’s a pleasure returning to FanGraphs after nearly four years away. Back in early 2022, I took a job as a pro scout for the Pittsburgh Pirates and I’ve been scouting minor leaguers ever since. In a few cases, I had a role in bringing players to Pittsburgh. It was a blast and I am grateful for the experience.

But for as much fun as I had, the job wore on those around me. I spent more than 80 nights on the road last year, a grueling schedule that’s rough on families in any situation and was increasingly unreasonable in mine. When I joined the Pirates, I was 30, childless, and ready to stretch my legs after two years of lying low and masking up. In the intervening years, a series of significant events made it hard to balance my passion for scouting with my responsibilities at home. My wife and I had a baby. A year later, we found ourselves facing a cancer diagnosis and long-term treatment. Our parents started battling their own medical problems. Through it all, I tried to be around as much as I could, but the realities of my schedule led to stressful compromises. The logistics of doing the job while being more than a replacement-level family member were hard to manage. This past July, I pulled an all nighter and drove from Corpus Christi to Houston to catch a 6 AM flight back home to Seattle, stepped inside for a quick shower, and then bolted two hours north to Bellingham for a birthday party. During that last stretch, my wife made her annual gentle suggestion that another path was possible.

And what a path this is. FanGraphs’s reputation as a leader in baseball analysis is well earned, particularly in the prospect space. For as long as he’s been at it, Eric has done an incredible job of covering the landscape. From my perspective, the breadth, depth, and nuance of his analysis is worth the price of a Membership all by itself. I learned plenty from him before, during, and after our time working together in my first stint here. The listing for this position came at the perfect time and I applied with gusto: I loved working as a scout, but the opportunity to join Eric in a full-time capacity, to continue evaluating baseball players while also getting another couple of months at home, was too enticing to pass up.

In an accord between familiar and frenetic trading partners, the San Diego Padres sent Adam Frazier to the Seattle Mariners on Saturday in exchange for prospects Ray Kerr and Corey Rosier. It’s a bit of an odd move. The Padres, nominally in win-now mode, just shipped off a 3.5-win player for prospects. Meanwhile, the Mariners beefed up their thin infield, but at the risk of incurring a considerable opportunity cost in a free agent market that seemed tailor made for their needs.

Let’s touch on San Diego’s side first, since it’s the more perplexing one at a glance. Frazier is the big name in the deal. The National League’s starting second baseman in last summer’s All-Star Game, the 29-year-old hit .305/.368/.411 last season while accruing the aforementioned 3.5 WAR, though his production dipped following the trade. Always a good contact hitter, Frazier joined the game’s elite in 2021 with a 10.8% strikeout rate — only Michael Brantley, David Fletcher, and Kevin Newman whiffed less often. While 2021 may well have been his peak, Frazier’s been a pretty good player for a long time: Since debuting in 2016, he’s notched a 103 wRC+ and has averaged 2.4 WAR per 162 games. Contending teams looking to gain ground don’t usually trade away this kind of production, particularly from a player they just acquired last July.

Despite that, you can understand why the Padres considered him surplus to requirements. With no path to a starting job in the infield, and Ha-Seong Kim around to fill a multi-positional utility role, Frazier was a bit of a square peg on a roster of round holes. Yes, the Friars could have used him in the outfield — as they sometimes did last summer — but it’s not the best use of his skills. In theory, exchanging him for players who could offer the Pads more stick in the outfield or depth in the bullpen makes sense. Read the rest of this entry »

The last time we saw Justin Verlander pitch, he looked like his usual, dominant self. In six innings against Seattle, he allowed only three hits and two runs while striking out seven. As had been the case in his Cy Young season, he was a little dinger-prone, surrendering two blasts to an otherwise overmatched Mariners lineup. But in an Opening Day start played in unusual circumstances, his stuff looked as sharp as ever.

Unfortunately, that last outing was in July of 2020. Within the week, Verlander landed on the injured list with a forearm strain. Two months later, the future Hall of Famer announced that he was undergoing Tommy John surgery. The procedure sidelined him for all of 2021, his last season prior to reaching free agency.

The timing gave the Astros a difficult decision. With no recent performance to evaluate, Houston nonetheless extended their ace a qualifying offer, which forced Verlander to pick between testing a very uncertain free agent market and taking a $10 million pay cut. He ultimately turned down the QO, but not the Astros themselves. In news amusingly broken by his brother Ben, Verlander re-signed with Houston yesterday on a one-year, $25 million deal that includes a $25 million player option for a second year.

Last week, veteran reliever Joakim Soria hung up his spikes. In his typically understated fashion, he didn’t so much as announce his retirement as have it done for him, through his agent and a Ken Rosenthal tweet.

Soria was a two-time All-Star. He pitched for nine teams during his 14-year career, racking up 15.4 WAR and 229 saves, alongside a tidy 3.11 earned run average. In his first spell with the Royals, Soria established himself as one of the sport’s premier closers and was a bright spot on several forgettable Kansas City teams. He never quite recaptured that early-career form after an elbow injury in 2012, though he remained a dependable late-inning reliever for most of the last decade.

For all his success, Soria’s unusual path to stardom remains perhaps the most notable part of his career. Born to schoolteachers in Monclova, Soria grew up in Mexico. He signed with Los Angeles as a teenager, but pitched only four times for the Dodgers, all in the AZL back in 2002. After going two seasons without appearing in a game, Los Angeles released Soria in 2004 and he spent all of the 2005 season in the Mexican League. After posting solid but hardly spectacular numbers, San Diego took a flier on him. He only threw 11 innings in Low-A that next summer, though, and the Padres understandably left him off of their 40-man roster. Read the rest of this entry »

To calm everyone down from that saucy title, we’re going to start with a few simple facts. Starting in the postseason, Cody Bellinger has made a few adjustments. He’s shifted his position in the box, he’s striding more toward the pitcher (as opposed to the first base dugout), and he’s shown an ability to flatten his bat path on high fastballs. Anecdotally, he looks a little less stiff to me and his swing decisions seem better, but let’s ignore those last two for today and focus on the mechanical aspect.

Alongside these adjustments, Bellinger has been a better hitter in the playoffs. In 28 plate appearances, he’s batting .291/.392/.458, all against very good pitching. It’s not vintage Bellinger or anything, and it’s worth noting that he’s struck out plenty, nine times in nine games thus far. Still, it’s a heck of a lot better than the 48 wRC+ he spewed up in the regular season.

Let’s take a closer look at what he’s been doing lately, how it differs from his setup in the regular season, and why it may actually be significant. Read the rest of this entry »

A pizza stain on the new Armani. A chocolate chip cookie, fresh out of the oven, adorned with nine chips and one cat droplet. The middle five wishes of Elliot Richards. Game 5 of the 2021 NLDS.

The Dodgers won 2-1 in as tense and dramatic a contest as we’ve seen all year, one that ended with an inexplicable call from first base umpire Gabe Morales on Wilmer Flores’ check swing. For Los Angeles, it’s a fifth trip to the NLCS in six seasons, a triumph only made sweeter by the circumstances. In vanquishing their rivals, the Dodgers get the last laugh in a brilliantly played season series. Tonight’s game is vindication for Dave Roberts and his lineup choices, redemption for Cody Bellinger, and another line on Hall of Famer Max Scherzer’s remarkable resume. Fans of all stripes were treated to an exquisite contest in nearly every respect.

But like most neutrals, that last pitch is stuck in my craw. With two outs, Kris Bryant on first, and Flores at the plate, Scherzer fired a 1-2 slider. Flores started his swing but appeared to check it well in advance of the imaginary and arbitrary breaking point at which a take (usually!) becomes a swinging strike:

There isn’t much missing from Freddie Freeman’s sterling career. He’s won an MVP, hit for the cycle, racked up 42 WAR, captured a pair of Silver Sluggers, and has already made five All-Star teams. That’s not quite enough for Cooperstown on its own, but he’s probably only a few more star caliber seasons away from a pretty good Hall of Fame case, and given that he’s only 32, he’s got time to pad his resume. With apologies to a criminally under-photographed snowmobile ride with Chipper Jones, the only thing missing from Freeman’s career has been an iconic moment.

No longer. In the eighth inning of a 4-4 tie in Tuesday’s NLDS Game 4, Freeman stepped to the plate against Josh Hader. Hader, of course, is the sport’s best relief pitcher and an absolute terror against lefties. He hadn’t given up a homer to a lefty all year, hadn’t surrendered a run since July, and hadn’t given the two previous hitters much of a chance to hit his nasty fastball/slider combo. On his first pitch to Freeman though, his bender caught too much plate and one chance was all that Freeman needed:

Milwaukee mustered a leadoff single in the ninth, but never got any closer to tying the game. Freeman’s late dinger ultimately clinched the series, and ensured the Braves wouldn’t rue a day that could have been defined by risky gambles and opportunities missed. Read the rest of this entry »
