Mariners Rumors

Vesting Options Update: Giolito, Polanco, Strahm

By Anthony Franco | August 18, 2025 at 9:40pm CDT

The upcoming free agent class doesn’t feature a ton of players whose contracts contain vesting options. Marcus Stroman’s deal with the Yankees would’ve contained an $18MM player option had he reached 140 innings, but an early-season knee injury made that impossible. The Yanks released him earlier this month anyhow.

While Stroman’s option was a non-factor, a trio of players are closing in on their own vesting provisions.

Lucas Giolito, Red Sox RHP ($14MM club option converts to $19MM mutual option at 140 innings; $1.5MM buyout in either case)

Giolito is up to 106 2/3 innings across 19 starts. He needs another 33 1/3 frames to convert next season’s $14MM team option into a $19MM mutual provision. That’d allow him to decline his end and retest free agency as he heads into his age-31 campaign. He’d very likely do so and could command a three-plus year contract.

The righty’s season numbers aren’t exceptional. Giolito carries a 3.63 earned run average with a 19.6% strikeout percentage that is his lowest since his terrible 2018 campaign. He had a trio of blowups in his first seven appearances after missing all of last season to an internal brace surgery. He has been locked in over the past two-plus months. In his last 12 starts, Giolito carries a 2.34 ERA while averaging over six innings per appearance. His 20.4% strikeout rate still isn’t great, and he has benefitted from a .229 opponents average on balls in play, but he at least looks the part of a durable mid-rotation arm again.

Giolito has a good shot to reach 140 innings. He’d need to average a little under six innings per start over his next six appearances. If he stays healthy, he should take the ball at least seven times — which would give him leeway in case he has one bad outing in which he’s knocked out after two or three frames. Even a minimal injured list stint would take it off the table, though.

Chief baseball officer Craig Breslow said over the weekend that the Sox had no intention of changing Giolito’s workload to keep him from vesting the option. No front office executive would publicly admit otherwise, of course, but there’s no reason to doubt Breslow in this case. The Red Sox are trying to secure a postseason berth. Even if they were out of contention, limiting a player’s workload so they could exercise an option to keep that player at a below-market rate wouldn’t make for an especially good relationship. If he gets to free agency, Giolito could take aim at something like the three-year deals secured by Luis Severino ($67MM with an opt-out after the second season) and Sean Manaea ($75MM with deferrals).

Jorge Polanco, Mariners DH/2B ($8MM mutual option converts to $6MM player option at 450 plate appearances, escalates to $8MM player option at 550 plate appearances; $750K buyout in either case)*

Polanco re-signed with Seattle last offseason on a somewhat complicated deal that reflected his health uncertainty coming off left knee surgery. The deal contains an $8MM mutual option which would vest into a $6MM player provision if Polanco reaches 450 plate appearances. Polanco has taken 395 trips to the dish. He’s 55 plate appearances from reaching the vesting mark, and he’d escalate the player option price back to $8MM if he tallies another 155 trips before season’s end.

Initially, the Mariners looked to have struck gold with that surprise re-signing. Polanco blasted nine home runs while hitting .384 through the end of April. Even with knee and side discomfort limiting him to early-season DH work, he looked rejuvenated. Polanco’s production completely tanked over the next two months, however. He had a huge July but is back to a .213/.275/.298 showing in 14 games this month.

Polanco has hit .209/.283/.344 across 315 plate appearances since the beginning of May. His season batting line (.245/.310/.439) is still above-average, but there have been significant peaks and valleys. Cole Young has taken over at second base. While Eugenio Suárez’s impending free agency leaves an opening at third base, Polanco hasn’t shown he’s healthy enough to play there regularly. There’s a good chance the Mariners would buy out their end of the option if it remains a mutual provision. Polanco only needs to start another 13 or 14 games to give himself more security.

That shouldn’t be a problem with 36 games remaining on the schedule. The M’s have sat him in each of their past two games against left-handed opponents, but he continues to play regularly versus righties. He’s highly unlikely to get all the way to 550 PA’s to push the player option to $8MM, but he should easily unlock the $6MM player option that’ll give him the unilateral decision whether to return to free agency.

* The vesting provision also requires that Polanco hasn’t suffered a lower body injury that’d prevent him from being ready for Opening Day 2026.

Matt Strahm, Phillies LHP ($5.5MM team option becomes guaranteed at $7.5MM at 60 innings)*

Strahm’s extension with the Phillies contained a $4.5MM club option for the 2026 season. The southpaw has already pushed that to $5.5MM and will escalate it to $6.5MM when he records two more outs. He’s 10 2/3 innings away from hitting the 60-inning threshold, at which point the price jumps to $7.5MM and becomes guaranteed.

In his case, it’s probably immaterial. Even if Strahm suffers a minor injury that keeps him from getting to 60 frames, the Phillies would probably exercise the option. Strahm is having another impressive season, working to a 3.10 ERA with six saves and 14 holds. His velocity has dropped a tick and he has lost a few points on his strikeout rate, but he has still punched out an above-average 27.7% of opponents. Strahm is one of Rob Thomson’s more trusted setup arms.

* The vesting provision also requires that Strahm pass a postseason physical.

Mariners To Activate Bryce Miller On Tuesday

By Anthony Franco | August 18, 2025 at 8:40pm CDT

The Mariners are activating starter Bryce Miller from the injured list tomorrow, manager Dan Wilson tells reporters (including MLB.com’s Daniel Kramer). He’ll go opposite NL Cy Young candidate Cristopher Sánchez in the second game of their series against the Phillies. While Miller has been out for over two months, Seattle never transferred him to the 60-day injured list. They’ll therefore only need to make an active roster transaction tomorrow.

Miller will take an MLB mound for the first time since June 6. He has been sidelined since then by elbow inflammation. The righty received a platelet-rich plasma injection and was able to rehab without anything more invasive. He has made a trio of rehab starts with Triple-A Tacoma this month. Miller got up to 5 2/3 innings and 76 pitches in his most recent appearance last Wednesday. He allowed a pair of runs on two hits and a walk while recording four strikeouts.

Perhaps more importantly, Miller’s velocity has looked sharp on the rehab assignment. He’s averaging 96.4 MPH on his fastball, more than two ticks higher than his early-season MLB work. Miller struggled over his first couple months, allowing 5.73 earned runs per nine while averaging fewer than five innings per start. His 18.1% strikeout rate was down more than six percentage points compared to last season. Miller was one of the better pitchers in MLB a year ago, taking the ball 31 times and working to a 2.94 ERA across 180 1/3 frames.

Miller will try to recapture last year’s form as the M’s battle the Astros for the AL West crown. Seattle is a game and a half back while holding a 3.5 game cushion on the Guardians in the Wild Card picture. They’ve dropped five of their past six but have been aided by Houston losing four of their last six games. Miller will step into the rotation in place of rookie righty Logan Evans, who went on the IL with his own elbow issue last week.

Mariners Claim Domingo González

By Darragh McDonald | August 12, 2025 at 1:35pm CDT

The Mariners announced that they have claimed right-hander Domingo González off waivers from the Braves and assigned him to Triple-A Tacoma. Atlanta designated him for earlier this week when they claimed righty Connor Seabold. Seattle’s 40-man roster had a vacancy but is now full.

González, 25, has no major league experience yet. Originally an international signing of the Pirates, Atlanta nabbed him in the minor league phase of the 2022 Rule 5 draft. A couple of years later, after the 2024 campaign, Atlanta added him to their 40-man roster to prevent him from reaching minor league free agency.

He had done some starting while in the Pirates’ system but has been almost exclusively a reliever since joining the Braves. His only two starts since switching organizations were two-inning stints as an opener. Over the 2023 and 2024 seasons, he logged 106 1/3 innings with a 3.55 earned run average. His 11.9% walk rate was a bit on the high side but he struck out 34.3% of opponents.

Given that performance, it’s understandable that Atlanta didn’t want him to get away and gave him a roster spot. But his results have backed up a bit this year. He has thrown 42 Triple-A innings with a 4.29 ERA, 21.4% strikeout rate and 11.5% walk rate. Those numbers seemingly prevented him from getting a big league call-up and also nudged him off the 40-man and onto the waiver wire.

For the Mariners, they had a free roster spot and have used it to scoop up González. Since he is in his first of three option years, the M’s could potentially be patient in trying to get him back on track. He has no major league service time yet, so he’ll be cheaply controllable for years to come if he can develop into a serviceable big league arm, though he’ll first have to show enough promise to hang onto a roster spot.

Poll: Who Had The Best Deadline In The AL West?

By Nick Deeds | August 7, 2025 at 4:10pm CDT

The trade deadline has come and gone. While trade season was slow to get started this year, when all was said and done, there were several dozen trades made in a flurry of movement over the final few days before the deadline arrived. The full impact of these trades won’t be known for years to come, but that doesn’t mean we can’t analyze the deals and decide whose haul looks the best right now. Over the next week-plus, MLBTR will be running a series of polls asking which club in each division had the best deadline. So far, the Phillies, Reds, and Padres have each come out on top in their respective divisions. Today, we’ll be moving on to the American League with the AL West. A look at each of the five clubs, listed from best to worst record in 2025:

Houston Astros

The Astros made one of the most shocking moves of the deadline when they brought Carlos Correa home in a trade with the Twins. Adding Correa back to the mix creates something of a positional logjam on the infield for the club in the long-term, but with third baseman Isaac Paredes unlikely to return this season due to a severe hamstring injury, Correa shores up the infield in a big way and cost the club virtually nothing other than money. Two more players were acquired to help round out the club’s position player mix: infielder Ramon Urias and outfielder Jesus Sanchez.

All three are controlled beyond the 2025 season, and while Sanchez cost the Astros rookie right-hander Ryan Gusto, no upper-level prospects changed hands in the club’s trio of deals. That ability to add long-term talent without surrendering the best prospects in the system was impressive, though the roughly $70MM they’ll be paying Correa over the life of his contract is a significant outlay and they failed to add the starting pitcher they were hoping could fill out the middle of the rotation behind Framber Valdez and Hunter Brown.

Seattle Mariners

The Mariners’ moves at the deadline were arguably even splashier than those in Houston. While the club acquired three rental players without any team control beyond the current campaign, it’s hard to argue against the fact that they’ve significantly upped their chances of winning both the AL West and even the World Series this year. Adding Eugenio Suarez and Josh Naylor to the infield corners in separate deals with the Diamondbacks represents a sizable upgrade over Luke Raley and Ben Williamson.

Meanwhile, the return (Tyler Locklear and a quartet of pitching prospects outside of Top 100 consideration) was lighter than what was required to bring in high-end controllable talents at this deadline. The Caleb Ferguson trade with the Pirates follows a similar path. The swap gives a club in need of left-handed help in the bullpen a steady, capable setup man who throws from the left side and can partner with Gabe Speier. That deal cost only Class-A pitching prospect Jeter Martinez, who has a 6.18 ERA in 16 starts this year. The Mariners opted to maximize short-term impact while doing so on a budget, and if they can overtake Houston in the West down the stretch, it would be hard to argue with them as the winners of the deadline.

Texas Rangers

With one-and-a-half games currently sitting between the Rangers and a postseason berth, it’s understandable that they acted quite aggressively this trade season. The focus of their haul was a trio of veterans: starter Merrill Kelly, setup lefty Danny Coulombe, and relief arm Phil Maton. Kelly stands out as arguably the best starting pitcher traded this summer, and the high cost (by the standards of a rental player) reflects that. The Rangers had to surrender their #5, #9, and #13 prospects according to MLB.com to get the deal done. Coulombe and Maton weren’t quite that expensive, but cost Texas a trio of prospects led by southpaw Garrett Horn, who was recently added to the club’s top 30 prospects list over at Baseball America at #25.

Shelling out significant prospect talent in order to make a serious run at a Wild Card berth is understandable, but what’s worth noting is that the Rangers also blew past the luxury tax in order to make those additions. Texas had worked meticulously throughout the season in order to stay below the first threshold and reset their penalties, but all of that work has now been thrown out in an effort to maximize their odds at making the postseason in 2025. The potential impact is clearly significant, but was that worth it for a team not even in playoff position on deadline day?

Los Angeles Angels

The Angels had a quiet deadline that was somewhat incongruent with their status as fringe (at best) contenders. The Halos are currently six games out of an AL Wild Card spot with a middling 55-60 record, but that didn’t stop them from doing some light buying this summer. Adding former top prospect Oswald Peraza in a minor swap with the Yankees made some sense, given the club’s long-term needs on the infield, Peraza’s many years of remaining team control and a low cost of acquisition.

Acquiring a pair of rental veterans for their bullpen in the form of Andrew Chafin and Luis Garcia was a bit more questionable, but the cost do so was low. Former 13th-round pick Sam Brown and 26-year-old lefty Jake Eder (whom the Angels had picked up off waivers earlier in the year) went back to the Nats in that swap.

The Angels didn’t really damage the farm, but they missed an opportunity to listen on players like Yoan Moncada, Taylor Ward, Luis Rengifo, and maybe even Reid Detmers. Selling even some short-term pieces could have helped restock a farm system that’s been viewed as below-average for quite some time. The urge to push in during a rare, mostly-healthy season for Mike Trout is an understandable one, but it’s hard to say with confidence that doing so was the right move.

The Athletics

Unlike the rest of the division, the Athletics were sellers this summer. They made just two trades. Shipping Miguel Andujar to the Reds wasn’t a major move but netted a 2022 fourth-rounder (right-hander Kenya Huggins) who now sits 25th among their prospects at MLB.com.

The vast majority of their deadline focused on the single biggest blockbuster that happened this July: the deal that sent closer Mason Miller and lefty starter JP Sears to the Padres. Acquiring a consensus top-five prospect in the sport by bringing in Leo De Vries is arguably enough to win the deadline by itself, but he was also joined by well-regarded prospects Braden Nett and Henry Baez, Double-A starters who could be part of the rotation mix in West Sacramento sometime next year.

Rounding out the package is rookie reliever Eduarniel Nunez, who struggled in his first appearances with the A’s but could bolster their bullpen in the future. It was a very strong return, with De Vries in particular standing out as the sort of elite prospect that almost never gets dealt at all, much less in a deadline trade for a reliever. On the other hand, giving up Miller with four-plus years of team control remaining (not to mention the possibility he could be converted into a rotation role in the future to further raise his value) could make this deal a tough pill to swallow, particularly if the 18-year-old De Vries does not blossom into an All-Star caliber player.

A number of different approaches characterized this deadline for the AL West. The Rangers and Mariners were very aggressive on bringing in short-term additions, while the Astros focused on bringing in controllable talent, the A’s brought in a haul for the future and the Angels largely stood pat. Who had the best deadline of that quintet? Have your say in the poll below:

AL Notes: Thornton, Buxton, Rays, Vargas

By Mark Polishuk | August 3, 2025 at 11:06pm CDT

The Mariners placed Trent Thornton on the 15-day injured list on Friday, and announced that the right-hander will miss the rest of the season due to a torn left Achilles tendon. Thornton had to be carted off the field after he suffered the injury in the ninth inning of Thursday’s 6-0 M’s win over the Rangers, as the reliever fell while leaving the mound to cover first base on an Adolis Garcia grounder. Follow-up tests revealed the unfortunate and expected news of an Achilles tear, and while a specific recovery timeline isn’t yet known, Thornton could be in jeopardy of missing some time at the start of the 2026 season.

Thornton has a 4.68 ERA over 42 1/3 innings for Seattle this season. A few particularly rough blowups have inflated his ERA, but his 17.8% strikeout rate is well below Thornton’s 26.2 K% from 2024. Owed a raise from his current $2MM salary in his final year of salary arbitration, Thornton will probably still be inexpensive enough that he won’t be non-tendered this winter, barring an unwelcome injury diagnosis. Since coming to the Mariners in a trade from the Blue Jays prior to the 2023 deadline, Thornton has been a workhorse out of Seattle’s pen, with a 3.65 ERA over 140 2/3 innings.

Outright Assignments: 8/3/25

By Mark Polishuk | August 3, 2025 at 4:46pm CDT

Here’s the latest on a few players recently designated for assignment, and now removed from their clubs’ 40-man rosters…

The Yankees announced that outfielder Bryan De La Cruz has cleared waivers and been outrighted to Triple-A. Because De La Cruz has more than three years of Major League service time, he has the right to elect free agency rather than accept the outright assignment, so it remains to be seen if he’ll remain in the organization. A regular with the Marlins from 2022-24, De La Cruz has struggled badly since a deadline trade to the Pirates last year, and his only MLB work in 2025 came in the form of 16 games with the Braves. New York claimed De La Cruz off waivers from Atlanta in May and the outfielder has hit .251/.323/.438 over 229 plate appearances for Scranton/Wilkes-Barre.
The Mariners outrighted Collin Snider to Triple-A after the right-hander cleared waivers. This is the first time Snider has been outrighted, and since he also doesn’t have the required amount of MLB service time, he’ll have to report to Triple-A rather than consider electing free agency. An underrated bullpen arm for the Mariners in 2024, Snider struggled to a 5.47 ERA in 26 1/3 innings this year and hasn’t pitched since a right forearm flexor strain sent him to the injured list two months ago. Snider had begun a minor league rehab assignment but he is out of minor league options, so the Mariners had to pursue the DFA/outright route rather than activate Snider directly back onto the 26-man roster.
The Phillies announced that right-handers Brett de Geus and Devin Sweet both cleared waivers and have been outrighted to Triple-A Lehigh Valley. The two pitchers were each designated on deadline day to create roster space for new acquisitions Harrison Bader and Matt Manning. De Geus made a single appearance with Philadelphia this season, and he has now tossed 63 1/3 innings over 61 career games at the big league level, posting a 7.39 ERA across his three seasons. Sweet has a 10.38 ERA over 8 2/3 career innings with the Mariners and A’s, all during the 2023 season. Both pitchers have previous outrights on their resume, so they can each elect free agency rather than accept the assignment to Triple-A.

Mariners To Acquire Eugenio Suarez

By Anthony Franco | July 31, 2025 at 3:01am CDT

The Mariners and Diamondbacks are reportedly in agreement on a trade that’ll send Eugenio Suárez back to Seattle. The D-Backs are getting rookie first baseman Tyler Locklear, reliever Juan Burgos and minor league pitcher Hunter Cranton in return. The deal is expected to be officially announced on Thursday.

Seattle has made a Suárez reunion their top deadline priority. They’ll get their man, bringing back a two-time All-Star who combined for 53 home runs in a Mariners uniform between 2022-23. The M’s made the regrettable decision to trade Suárez away after the ’23 season. That netted hard-throwing middle reliever Carlos Vargas but was primarily motivated by a desire to shed the $13MM that remained on the third baseman’s contract at the time.

While Suárez started his Arizona tenure slow, he’s been one of the best hitters on the planet dating back to the middle of last summer. Over the past calendar year, Suárez has hit 53 home runs with a .273/.332/.589 slash line. He’s tied with Kyle Schwarber and teammate Cal Raleigh for third in MLB in homers during that stretch. Only Shohei Ohtani and Aaron Judge have hit more. Suárez went on such a tear in the second half last year that the D-Backs had an easy call to bring him back on a $15MM club option that once looked likelier to be bought out.

Suárez has shown no signs of slowing down at age 34. He has mashed at a .248/.321/.577 clip across 433 plate appearances. He and Raleigh are tied for the MLB lead with 87 runs batted in. Only Raleigh, Ohtani, Judge and Schwarber have more home runs. He’d led the American League in strikeouts during both seasons in his first run with Seattle. The 12-year big league veteran has trimmed his strikeout rate by a few percentage points in Arizona. There’s still a decent amount of swing-and-miss, but it’s not at the same rate that surely alarmed the M’s front office a couple years ago.

The Diamondbacks were on the fringe of the NL Wild Card race as recently as two weeks ago. A sweep at the hands of the Astros sealed their fate as deadline sellers. Houston’s division rivals have ironically been the big beneficiary. The D-Backs began their sell-off by dealing Josh Naylor to Seattle last week. He displaced Luke Raley as the starting first baseman. Suárez rejoins him as an impact corner infield tandem. It’ll likely push light-hitting rookie infielder Ben Williamson back to Triple-A.

Seattle now runs out a lineup including Raleigh, Suárez, Naylor, Julio Rodríguez, Randy Arozarena, Jorge Polanco and J.P. Crawford. Right fielder Dominic Canzone has mashed since being called up from Triple-A in early June. It’s the imposing lineup that Seattle has tried for years to build alongside their elite rotation.

The M’s are nevertheless far from guaranteed to make the playoffs. They’re currently tied with the Rangers for the AL’s last Wild Card spot and sit five games back of Houston in the division race. They’ve poked around the market for another late-inning reliever. Seattle added left-hander Caleb Ferguson to the bullpen on Wednesday evening, but he’s more of a complementary piece. If the Mariners have another big move in them, it’d probably be in the late innings.

The Mariners are taking on nearly $5MM in salary still owed to Suárez for the stretch run. They assumed almost $4MM on Naylor and close to $1MM for Ferguson. It’s a significant change from an offseason in which ownership left the front office without much budgetary flexibility. They’re all-in as they try to capitalize on Raleigh turning in one of the greatest seasons ever by a catcher. Suárez and Naylor might be the two best impending free agent hitters to move. The acquisition should be very well received in the clubhouse, as Suárez is a highly-regarded teammate with whom much of the roster is familiar.

Seattle gave up a trio of players to make that happen. Locklear, 24, is the most intriguing. He’s a righty-hitting first baseman who could replace Naylor as Arizona’s long-term answer at that position. Seattle took the Virginia Commonwealth product in the second round in 2022. The 24-year-old doesn’t have much big league experience. He appeared in 16 games last season, hitting .156 while striking out 20 times in 49 plate appearances.

Plenty of hitters struggle in their first look at MLB pitching. Locklear has posted excellent minor league numbers. He’s a career .291/.392/.502 hitter against minor league arms. That includes a huge .316/.401/.542 showing in Triple-A this season. Locklear has connected on 19 home runs in 434 plate appearances. Seattle just recalled him this afternoon to replace Raley, who went down with back spasms. Instead, he’s off to Arizona, where he’ll probably jump directly onto the MLB roster.

Burgos, 25, could also get an MLB look in the near future. Seattle called up the 6’0″ righty in late June. Burgos didn’t get much of a look over a three-week stint in the big league bullpen. He made four appearances, working 6 2/3 frames of three-run ball with eight strikeouts. Burgos showed a five-pitch mix built around a low-90s cutter and a mid-90s sinker.

He doesn’t have elite velocity for a bullpen prospect, but he has punched out an above-average 26.1% of batters faced over 31 innings between the top two minor league levels. Burgos has an absurd 0.87 earned run average in that stretch. Baseball America ranked him 25th among Seattle prospects, while he placed 17th at MLB Pipeline. Both outlets feel he’s a low-variance middle relief type.

Cranton is further off. Seattle drafted him in the third round last summer out of the University of Kansas. He was an underslot signee as a senior draft pick. MLB Pipeline ranked the 6’3″ righty as the #16 prospect in the Seattle system. He placed 23rd on Eric Longenhagen’s writeup at FanGraphs last month. He did not rank among BA’s top 30. Cranton has an upper-90s fastball and a slider. He was on the minor league injured through the end of June after being struck in the head by a comebacker during Spring Training, Longenhagen notes.

None of the three players are top-end prospects. The lack of a true headliner might come as a disappointment to Arizona fans, but it reflects teams’ general reluctance to give up elite young talent for rentals. The D-Backs added a pair of controllable players who could play meaningful roles as they try to return to competitiveness in 2026. In the meantime, they’ll eventually get their first real look at third base prospect Jordan Lawlar. Lawlar isn’t quite ready to return from a June hamstring injury that sent him to the Triple-A injured list, but he should get 4-6 weeks of everyday playing time to close the season.

Arizona has traded three impending free agents: Naylor, Suárez and Randal Grichuk. They’ll move at least one and possibly both of Zac Gallen and Merrill Kelly tomorrow. They could also try to move an outfielder or short-term relievers like the currently injured Shelby Miller or Kevin Ginkel. There’s plenty more to come from the Snakes over the next 18 hours.

Mariners Designate Collin Snider For Assignment

By Darragh McDonald | July 30, 2025 at 5:50pm CDT

The Mariners announced that right-hander Collin Snider has been reinstated from the 15-day injured list and designated for assignment. That opens a 40-man spot for left-hander Caleb Ferguson. It was reported earlier today that the M’s were acquiring Ferguson from the Pirates and that deal is now official.

Snider, 29, was claimed off waivers from the Diamondbacks ahead of the 2024 season. He was great for the Mariners last year, giving them 41 2/3 innings with a 1.94 earned run average. He struck out 27.8% of batters faced while only giving out walks at a 7.7% clip.

This year, however, has not been as pleasant. Snider posted a 5.47 ERA in 26 1/3 innings before hitting the 15-day injured list in early June due to a right forearm flexor strain. He began a rehab assignment at the start of July but hasn’t been sharp there either. He has a 5.06 ERA in 10 2/3 Triple-A innings as part of that rehab assignment.

Snider is out of options and would need to be added back to the active roster at the end of his rehab assignment. It seems the M’s didn’t intend to do that. They have added Ferguson to their bullpen already and reportedly plan to keeping adding to the relief corps, so Snider has been squeezed out.

He now heads into DFA limbo. The M’s could try to work out a trade in the next 23 hours. If they can’t do that, Snider will end up on waivers. Perhaps he could garner interest from other clubs based on last year’s success, though this year’s struggles and his injury will tamp down the excitement.

Mariners Acquire Caleb Ferguson

By Steve Adams | July 30, 2025 at 5:30pm CDT

The Mariners acquired left-handed reliever Caleb Ferguson from the Pirates for minor league right-hander Jeter Martinez. Righty Collin Snider has been designated for assignment as the corresponding move. Ferguson is playing on a one-year, $3MM contract and is a free agent at season’s end.

Ferguson, 29, is in the midst of a strong season with Pittsburgh. He’s pitched 43 1/3 innings and logged a 3.74 ERA with a 19.3% strikeout rate and 8% walk rate. He’s allowed only one homer on the season and kept just under 50% of his opponents’ batted balls on the ground.

While Ferguson isn’t a flamethrower who misses bats in bunches — he’s averaging 94.1 mph on his four-seamer this season — he avoids hard contact better than any other reliever in the game. Ferguson’s 83.5 mph average exit velocity is the lowest of any pitcher in Major League Baseball (min. 40 innings). His 25.2% hard-hit rate is second, trailing only Padres standout lefty Adrian Morejon.

Ferguson has pitched in parts of seven major league seasons. He’s totaled a 3.69 earned run average in 305 big league innings. The southpaw typically misses more bats than he has in 2025 (career 26.4% strikeout rate), but he’s currently sporting his lowest walk rate since the shortened 2020 season and has never limited hard contact as well as he’s managed to this year. Ferguson has been an absolute monster against left-handed opponents, limiting them to a pitiful .167/.257/.182 slash in 74 plate appearances. He’s also been strong against right-handers, however, holding them to a .250/.327/.354 slash. It’s not quite dominant, but this is his best production versus righties since 2022.

The Mariners have only had one reliable left-hander in their bullpen this season: Gabe Speier. They’ve given brief looks to Tayler Saucedo, Blas Castaño and Jhonathan Diaz, but no one from that group has even pitched five innings out of the big league bullpen. Ferguson gives skipper Dan Wilson a second southpaw option who, like Speier, can handle both lefties and righties.

Seattle is known to be on the lookout for high-impact talent at the back of the bullpen. Ferguson isn’t necessarily that marquee arm they’ve been seeking, but in all likelihood he’ll be just one of multiple relievers acquired. The Mariners are reportedly making a run at Twins closer Jhoan Duran and have also been tied to young, controllable bullpen arms in Colorado like Seth Halvorsen and Juan Mejia.

As for the Pirates, they’ll spin their low-cost investment in Ferguson into the 19-year-old Martinez. The 6’4″ righty, signed out of Mexico for a $600K bonus during the 2022-23 signing period, has started 16 games against older and more advanced competition with the Mariners’ Low-A affiliate. He’s struggled to a 6.18 ERA due in no small part to a 13.2% walk rate.

Martinez posted strong ERAs in prior seasons with the Mariners’ affiliate in the Dominican Summer League, however, and he’s shown plenty of ability to miss bats with a mid-90s fastball that can scrape triple digits. Baseball America ranked Martinez 22nd among Seattle prospects earlier this month. FanGraphs ranked him 15th in the system last month, where Eric Longenhagen praised that heater and a pair of secondary pitches (slider, changeup) that could be plus pitches. Command is the biggest issue, but Martinez is still more than two years away from needing to be added to the 40-man roster, so the Pirates will have awhile to try to rein in the free passes and keep him in the rotation. If a move to the bullpen ends up being necessary, it’s easy enough to imagine Martinez’s already impressive fastball playing up a bit further.

Ken Rosenthal of The Athletic reported the Mariners were acquiring Ferguson. Adam Jude of The Seattle Times reported that Martinez was going the other way.
