Mariners Outright Jesse Hahn

By Mark Polishuk | April 12, 2025 at 2:53pm CDT

The Mariners announced that right-hander Jesse Hahn has been outrighted to Triple-A Tacoma.  Hahn cleared waivers after being designated for assignment earlier this week.  Since Hahn has more than three years’ worth of MLB service time, he has the right to reject that outright assignment in favor of free agency, but there isn’t yet any word on whether or not Hahn will test the market or stick in Seattle’s organization.

Hahn already quickly re-signed with the Mariners on a fresh minor league deal after they released him from a previous minors contract at the end of March, which might hint that Hahn will again stick around in Triple-A.  Hahn’s return to the M’s ended up landing the righty his first taste of Major League action since 2021, after the Mariners selected his contract and deployed him in two games last week.  Hahn threw four scoreless frames in those two appearances, albeit with three hits and four walks in that limited sample.

The 35-year-old Hahn has a 4.17 ERA over 315 1/3 career innings with the Padres, A’s, Royals, and Mariners.  Health issues have cost him big chunks of his career, as Hahn has undergone two Tommy John surgeries, and he also didn’t pitch at all in 2022-23 while recovering from a shoulder issue.  He returned to action to post a 4.29 ERA across 50 1/3 frames at the Triple-A level for the Dodgers and Mariners, as control issues continued to limit Hahn’s effectiveness.

Mariners Exploring Infield Market

By Steve Adams | April 11, 2025 at 1:35pm CDT

Injuries have quickly changed the complexion of the Mariners’ infield. Second baseman Ryan Bliss will miss four to five months after suffering a tear in his left biceps and undergoing surgery. First baseman Luke Raley has shifted to the outfield in the wake of a fracture in Victor Robles’ shoulder, which will sideline him for around 12 weeks. Jorge Polanco is currently relegated to DH work and won’t play the infield for another week or two, per Adam Jude of the Seattle Times. He underwent knee surgery back in October and is dealing with some discomfort in his side as well.

With those early changes to the infield composition, the Mariners are poking around the market for potential external additions, Jude further reports. A major trade this time of year is rare but not unheard of. The Brewers just picked up young right-hander Quinn Priester in a trade with the Red Sox earlier this week, helping to shore up an injury-ravaged rotation in Milwaukee. Last year’s trade of Luis Arraez from Miami to San Diego occurred in early May. Of course, the Mariners spent the bulk of the offseason pursuing trades to bolster their infield and ultimately wound up making a series of small free agent signings instead — clearly not finding a match to their liking.

It’s unlikely that there are any teams that have strongly rethought their status as postseason hopefuls just a few weeks into the season. As such, it’s unlikely that there are any players available on the trade market at present whose teams weren’t willing to discuss them over the winter. If the Mariners couldn’t find an offseason trade of note to bolster their infield, it’s hard to envision them suddenly doing so now.

That said, Jude notes that Seattle’s front office is “combing” other rosters and looking at veteran players who are on minor league deals elsewhere. Many veterans will have opt-out dates and upward mobility clauses in April. Article XX(b) free agents (i.e. six-plus years of MLB service, finished the preceding season on a major league roster/injured list) who signed minor league contracts have a uniform opt-out opportunity on May 1. MLBTR took a look at 36 such players late in camp, though the majority this year happened to be pitchers.

This type of acquisition wouldn’t necessarily be a sexy one, but the Mariners have gotten no production to date out of Rowdy Tellez or Donovan Solano, and they’re hitting .200/.303/.333 as a team as of this writing. The bar for improvement is fairly low. Tellez and Solano will surely get some runway to turn things around, but it’s sensible to looking at other, similar veteran options who could potentially be had on the cheap. Among the veteran infielders on minor league deals and hitting well in Triple-A with other clubs are Christian Arroyo (Phillies), Scott Kingery (Angels), Harold Castro (Royals), Nick Gordon (Royals) and Jake Lamb (Giants).

Help could always come from the farm system as well. Jude writes that the organization is prioritizing top prospect Cole Young’s development at the moment and doesn’t want to rush him to the big leagues but could consider an accelerated path for third baseman Ben Williamson. Young is hitting .178/.302/.267 in Triple-A at the moment anyhow, making it tough to consider him an upgrade. Williamson is a plus defender at third base who’s gotten some reps in the middle infield, too. He’s light on power but has plus contact skills and is out to a .286/.314/.347 start in Tacoma. He batted .283/.375/.394 in 541 plate appearances between High-A and Double-A last year. First baseman Tyler Locklear didn’t hit in his big league debut last year but is slashing .286/.359/.457 through his first nine games in Triple-A this season.

If Seattle’s offensive doldrums continue much longer and there’s no help to be found outside the organization, it stands to reason that Williamson and/or Locklear could get early looks to help right the ship.

Ryan Bliss To Miss 4-5 Months Due To Biceps Surgery

By Darragh McDonald | April 10, 2025 at 2:35pm CDT

The Mariners today provided an update on infielder Ryan Bliss, who was placed on the 10-day injured list yesterday with a torn left biceps. Today’s announcement relays that an MRI confirmed the severity of the tear and the need for surgery, with an expected recovery timeline of four to five months.

It’s obviously a frustrating development for Bliss and the club. It’s unclear if that timeline includes an eventual rehab assignment or if it will take that long just to begin rehabbing. Either way, he will miss the majority of the campaign even in a best-case scenario and it seems possible that he won’t return in 2025 at all.

For the team, it’s the second big blow to their position player group in the past few days. Víctor Robles has a shoulder fracture and is expected to miss about three months while avoiding surgery, though that timeline could change if surgery eventually is required. Now Bliss is also going to be sidelined for multiple months.

Lack of offense was an issue for them last year and their infield was particularly concerning. Justin Turner and Jorge Polanco became free agents at season’s end, with Josh Rojas non-tendered as well. That left them with J.P. Crawford at shortstop and a few role players or unestablished young guys as candidates for the other spots. There were many offseason rumors surrounding their infield pursuits but they only made a couple of modest moves, bringing back Polanco to play third and signing Donovan Solano to chip in at the corners in a part-time/platoon role.

That left second base open for internal options, including Bliss, a nice opportunity for him. He came into 2025 with just 33 major league games under his belt but some intriguing minor league numbers. Over 2023 and 2024, he produced a combined line of .290/.378/.497 for various minor league clubs. That production led to a wRC+ of 120, indicating he was 20% above league average. He also stole 105 bases in 133 tries. The M’s acquired him from the Diamondbacks as part of the July 2023 trade that sent Paul Sewald to the desert.

Bliss hit just .200/.282/.314 to start this year but in a small sample of just ten games. He won’t be able to adjust that line any time soon. Between him and Robles, the club has to improvise a new lineup around two vacancies. Polanco is battling some knee issues and has been serving as the designated hitter lately. Luke Raley has moved from first base to right field to replace Robles, with Rowdy Tellez taking over at first, platooning with Solano. Dylan Moore, Miles Mastrobuoni and Leo Rivas figure to cover third and second base, at least until Polanco can take the field again. Cole Young is one of the top prospects in the league and could take over the keystone at some point but he is hitting .171/.292/.244 through 11 Triple-A games to start the year.

All clubs deal with injuries but it’s perhaps a little more concerning for Seattle. They didn’t have many resources available for upgrading their lineup this winter, giving them a somewhat narrow margin for error to begin the year. They have now limped out to a 5-8 start and will be without two lineup regulars for multiple months. Bliss should be moved to the 60-day IL whenever the Mariners need a roster spot.

Mariners Put Ryan Bliss On IL Due To Biceps Tear, Designate Jesse Hahn

By Steve Adams and Darragh McDonald | April 9, 2025 at 1:10pm CDT

The Mariners designated right-hander Jesse Hahn for assignment today amid a series of roster moves, per a club announcement. Right-hander Casey Lawrence was selected from Triple-A Tacoma in his place. And, in a concerning bit of injury news, Seattle placed infielder Ryan Bliss on the 10-day injured list due to a torn left biceps. He suffered the tear during a swing in last night’s game. A timeline for his recovery hasn’t been provided, but given the nature of the injury, it seems all but guaranteed that Bliss will be facing a notable absence. Infielder Leo Rivas is up from Tacoma in his place.

Bliss wasn’t off to a roaring-hot start this season, as he’s currently sporting a line of .200/.282/.314. Regardless, the injury further depletes the Seattle infield, which has been an issue for quite a while. All throughout the offseason, they were looking to make notable upgrades to their group on the dirt. Their moves ended up being pretty modest, with Jorge Polanco re-signed and moved from second to third base. Donovan Solano was also signed to be a part-time contributor.

Going into the season, Bliss and Dylan Moore were the top candidates to play second base. Lately, Polanco has been in and out of the lineup due to some soreness in his side, taking the designated hitter spot whenever he’s been healthy enough to play. That has left Moore at third and Bliss at second. Luke Raley has been playing right field to cover for the injured Víctor Robles, opening first base for Rowdy Tellez and the DH spot for Polanco.

It’s less than ideal for a club that has been searching for more offense for a while. The lack of thump in the lineup seemed to be their undoing last year and they weren’t able to make a significant upgrade in the winter. The team has a combined .199/.301/.329 line and 92 wRC+ at the moment and a 4-8 record which has them in the basement of the American League West.

Bliss wasn’t the most essential part of their foundation but it’s another brick removed. Rivas has a .233/.333/.274 line in his big league career but hit .296/.441/.424 in Triple-A last year and is out to a hot start this year, slashing .304/.429/.609 through seven games. He will jump into the infield group though the M’s also have Solano, Moore, Tellez, Polanco and Miles Mastrobuoni in the mix for playing time alongside shortstop J.P. Crawford.

The pitching moves are a reflection of the fact that their recent schedule has been a grind. They lost an 11-inning game on Friday, the first of the six-game stretch, using nine pitchers in that contest. They had fairly regular bullpen usage in the following three games but then had another rough one last night, using seven pitchers in a 12-inning marathon.

With the group fairly taxed overall, they’ve decided to bring in a fresh arm. Lawrence is a 37-year-old who has been called on for such duties before, having worked long relief gigs with the Blue Jays, Cardinals and Mariners in the past. Signed to a minor league deal in the offseason, he’s been pitching in the Triple-A Tacoma rotation to start this year. His last outing lasted 4 2/3 innings on April 4, so he should be able to mop up a few frames today, if needed. After that, it wouldn’t be a surprise to see him bumped off the roster. He is out of options and the Mariners have a much-needed off-day tomorrow.

Hahn, 35, just made it back to the majors a few days ago after a long absence. The M’s selected his contract on April 5, his first time in the bigs since 2021. He has pitched four innings for the M’s since then, including the final two innings of last night’s extra-inning contest. He hasn’t been charged with an earned run yet this year but got a tough L last night when the Manfred Man came around to score in the 12th.

He’s now off the 40-man and will be in DFA limbo for a bit, a week at most. The waiver process takes 48 hours, so the Mariners theoretically have five days to explore trade interest. He has a 4.17 ERA in 315 1/3 bg league innings. He missed 2022 and 2023 due to a shoulder injury then pitched in Triple-A last year with a 4.29 ERA over 50 1/3 innings.

Víctor Robles Likely To Miss About 12 Weeks

By Steve Adams | April 8, 2025 at 2:03pm CDT

The Mariners today provided an update on outfielder Víctor Robles, who was placed on the 10-day injured list yesterday due to a left shoulder dislocation. Today’s update says that the dislocation caused a small fracture in the humeral head in his left shoulder. The club believes that the fracture will heal without surgery, though Robles will be continually monitored to ensure that is the case. Even if he does continue to avoid surgery, the club estimates it will take him six weeks to heal, followed by a six-week rehab process. That suggests he will miss about 12 weeks even in a best-case scenario.

Of course, if there are any setbacks along the way or if it’s determined that Robles will instead require surgical intervention, that timeline would change. In either scenario, given that Robles is already looking at an absence that would extend to around the All-Star break, doubts about his ability to return this season could arise. For now, however, the Mariners are surely relieved that the injury doesn’t look to be season-ending in nature.

Robles, 27, was a longtime top prospect with the Nationals who debuted in as a 20-year-old in 2017 but never quite found his footing as a regular in Washington. He looked on the cusp of a breakout when he hit .258/.328/.430 with plus defense in 2018-19, his age-21 and age-22 seasons, but in 1124 plate appearances from 2020 through the time of his release last May, he batted only .222/.301/.308.

The Mariners signed Robles to a big league deal early last June and were almost immediately rewarded for their show of faith. He filled a bench role early on but played so well in a limited role that he forced himself into the everyday lineup before long. In 77 games with Seattle, Robles turned in a superlative .322/.393/.467 batting line with four homers, 20 doubles and an eye-catching 30 steals in just 31 tries.

Robles was never going to sustain the .388 average on balls in play that propped up his batting line, but he also showed vastly improved contact skills, cutting the 24% strikeout rate he’d displayed from 2020-24 (27.3% with the Nats last year) all the way to 16.8% as a Mariner.

With Seattle, Robles proved much more aggressive, increasing his swing rate at pitches over the plate by several percentage points and also improving his contact rate on said swings. He swung at only 49% of pitches over the plate up through the 2023 season and made contact on 84.5% of those swings; with the Mariners, he offered at 53% of pitches in the zone and made contact at an 87.1% clip.

Even with some expected regression, the Mariners’ version of Robles looked like a more balanced hitter than the one who’d spent several years struggling in D.C. The Mariner front office clearly believed that to be the case, as Robles inked a two-year, $9.75MM contract covering his first two free agent years last summer. The deal spans the 2025-26 campaigns and includes a club option for 2027.

Now, Robles will spend around half of that contract’s first season (at least) on the shelf. He’d been slotted in as the everyday right fielder with Randy Arozarena in left field and Julio Rodriguez in center field. The Robles injury likely paves the way for more Luke Raley to see more outfield time. He’d originally been expected to play more first base in 2025, but a big performance in spring training from Rowdy Tellez forced the Mariners to reevalute. Seattle released Mitch Haniger and committed to Tellez and Raley splitting the load between first base and DH.

Raley and Dominic Canzone figure to get more time in the outfield. It’s also possible that utilitymen Miles Mastrobuoni and Dylan Moore could log some reps there. All three of Raley, Canzone and Mastrobuoni are left-handed hitters, so a platoon arrangement among them isn’t likely. Raley and the righty-hitting Moore could make sense as an on-paper platoon, but Moore has been used as an infielder exclusively thus far and played a career-low 138 innings in the outfield last year.

However it shakes out, the Robles injury is a significant setback for a Mariners club that currently ranks 21st in the majors in runs scored (36). It’s also likely to result in a defensive downturn; the early marks from Robles this season have been uncharacteristically below average, but he’s generally graded as a strong defender in center and is viewed as a potential plus defender in a corner.

Guardians Acquire Cody Bolton

By Darragh McDonald | April 8, 2025 at 1:50pm CDT

The Mariners announced that right-hander Cody Bolton has been traded to the Guardians for cash considerations. He was designated for assignment a few days ago when the M’s selected Jesse Hahn. The Guardians transferred John Means to the 60-day injured list to open a 40-man roster spot and optioned Bolton to Triple-A Columbus.

Bolton, 27 in June, has 40 innings on his major league track record at this point. Between the 2023 Pirates and 2024 Mariners, he has a combined 5.40 earned run average. His 20.5% strikeout rate, 12.6% walk rate and 39.5% ground ball rate are each a bit worse than league average.

The Guards are presumably more interested in his minor league work. After missing the entire 2021 season due to a knee injury, he has since thrown 153 2/3 Triple-A innings with a 3.40 ERA. His 11.1% walk rate is still on the high side but he struck out 25% of opponents in that time. He averages almost 95 miles per hour on both his four-seam fastball and a sinker, as well as throwing a changeup, sweeper and cutter.

For Cleveland, they effectively had an open 40-man spot. Means underwent UCL surgery in June of last year. He also underwent Tommy John surgery on that same ligament in April of 2022. He’s likely to be out until midseason even in a best-case scenario. They have used that free roster spot to grab Bolton and stash him in Triple-A as some extra depth. He has less than a year of service time and can be cheaply retained into the future. However, he has just one option year remaining, so he’ll be out of options next year if he burns his last one here in 2025.

Mariners Outright Hagen Danner

By Darragh McDonald | April 7, 2025 at 5:48pm CDT

The Mariners announced that right-hander Hagen Danner cleared waivers and will be outrighted to Triple-A Tacoma. The righty had been designated for assignment last week when the club added Luis F. Castillo to the roster. Seattle also placed Victor Robles on the 10-day injured list with a dislocated left shoulder and recalled Dominic Canzone — moves that were reported yesterday.

Players have the right to reject an outright assignment and elect free agency if they have either a previous career outright or at least three years of major league service time. Neither applies to Danner, so he’ll stick with the Mariners as depth but without taking up a roster spot.

The M’s are likely glad about that. They were intrigued enough by Danner to grab him off waivers from the Blue Jays in January. His track record isn’t long, for a few reasons. He was drafted as a catcher and tried his hand at that spot for a few years before moving to the mound. Since taking the hill, he has posted some decent rate numbers but has also been held back by some injuries.

In the majors, he has just one third of an inning to his name. In the minors, he has tossed 116 2/3 innings from 2021 to the present. Thanks to various injuries, he hasn’t hit the 40-inning mark in any individual season. But he has a 2.93 earned run average, 28.3% strikeout rate and 8.7% walk rate.

Over the course of a long season, the Mariners will surely need fresh arms from time to time, as all clubs do. If Danner gets back to the majors, he still has one option year and just 52 days of service time.

Victor Robles Carted Off Field With Shoulder Injury

By Nick Deeds | April 6, 2025 at 10:47pm CDT

10:47pm: Ari Alexander of KPRC2 reports that Canzone is set to be recalled to the big leagues by the Mariners. That seemingly suggests that Robles is ticketed for the injured list, which Jon Morosi of MLBNetwork reported was likely earlier this evening, though no official move has been made to this point.

6:08pm: Mariners outfielder Victor Robles made an outstanding catch late in today’s game against the Giants, but the moment quickly turned worrisome when Robles crashed into the right field netting in foul territory. As noted by multiple reporters, including Adam Jude of The Seattle Times and Daniel Kramer of MLB.com, Robles exited the game and was carted off the field clutching his left arm. As noted by Jude, manager Dan Wilson told reporters that Robles suffered a shoulder injury and is undergoing initial tests to determine the exact issue.

It’s potentially devastating news for the Mariners, for whom Robles has emerged as a spark plug in all aspects of the game since he was signed by Seattle back in June after being released by the Nationals earlier that year. In 77 games for Seattle the rest of the way, Robles hit a phenomenal .328/.393/.467 with a wRC+ of 154. He also played solid defense across all three outfield spots and went 30-for-31 on the basepaths en route to 3.2 fWAR in just 262 trips to the plate for the Mariners last year. It was such a strong performance that the club signed Robles to a two-year extension that guarantees him $9.75MM and keeps him under team control through the end of the 2027 season thanks to a $9MM team option for a third year.

That 2024 breakout season represented a remarkable comeback for Robles, who was considered the best prospect in the Nationals’ system and among the top prospects in the entire sport as he came up through the minor leagues alongside Juan Soto. Unfortunately, injuries have dogged Robles all throughout his career. He appeared in just 530 games in parts of eight seasons in D.C. due to elbow, ankle, back, and hamstring injuries among other ailments. He’s only had one full season in the majors over the years, his 2019 rookie season with the club, and since then has only reached even 400 plate appearances in a season a single time.

It’s impossible to say with certainty to what extent the injuries led to Robles, who hit a disappointing .236/.311/.356 during his time with the Nationals, to under perform the expectations associated with his top prospect status. Even so, it’s without a doubt that both he and the Mariners were surely hoping his fresh start in Seattle last year would afford him the opportunity to prove himself healthy and effective in the big leagues over an extended period of time. While even an approximate timetable for Robles’s return to action won’t be clear until the Mariners provide more details regarding the nature of his injury, it seems safe to say that Robles will miss at least some time due to the injury.

In terms of options to replace Robles in the lineup, they’re relatively few and far between. Dylan Moore has gotten off to a hot start this year but is currently stepping in for Jorge Polanco at third base while Polanco nurses a sore knee. Dominic Canzone is on the 40-man roster at Triple-A and capable of playing the outfield, or the club could move Luke Raley from first base back into the outfield while giving first base to some combination of Donovan Solano, Austin Shenton, and Tyler Locklear. Regardless of which options they ultimately go with to fill in for Robles while he’s out, an extended absence from the outfielder could be tough for the club to handle given their relatively lackluster depth options on the positional side of things.

Mariners Designate Cody Bolton For Assignment

By Nick Deeds | April 5, 2025 at 3:26pm CDT

The Mariners announced this afternoon that they’ve designated right-hander Cody Bolton for assignment. Bolton’s 40-man roster spot will go to right-hander Jesse Hahn, whose contract has been selected from the minors. Left-hander Tayler Saucedo was optioned to Triple-A to make room for Hahn’s addition to the active roster.

Bolton, 27 in June, was a sixth-round pick by the Pirates back in 2017 and made his big league debut with Pittsburgh in 2023. That first stint in the majors did not go especially well, as the righty posted a lackluster 6.33 ERA (72 ERA+) with a 20.6% strikeout rate against a hefty 14% walk rate in 21 1/3 innings of work. While he pitched better at Triple-A Indianapolis, with a 3.86 ERA and a more reasonable 9.2% walk rate, that still wasn’t to convince the club to keep Bolton on their 40-man roster throughout the winter; in early November, the club traded Bolton to the Mariners in a cash deal.

Bolton’s time in Seattle went better than his time in Pittsburgh, but still left something to be desired. The right-hander pitched impressively for the Mariners at Triple-A Tacoma, with a 3.07 ERA in 29 1/3 innings of work that’s made all the more impressive by the inflated offensive environment of the Pacific Coast League. Strong as that work was, however, the righty still posted a below-average 4.34 ERA (85 ERA+) with a 20.5% strikeout rate and a 10.8% walk rate that were largely reminiscent of his time with the Pirates. While Bolton stuck with the Mariners on the 40-man roster throughout this past offseason, a rough start to the 2025 campaign at Triple-A where he’s surrendered three runs in two innings of work was evidently enough for Seattle to pull the plug. The club will now have one week to either trade Bolton or attempt to pass him through waivers. Should he clear waivers successfully, the Mariners can outright him to the minor leagues as a non-roster depth option going forward.

The departure of Bolton makes room for Hahn, whose debut with the Mariners will be his first MLB appearance since 2021. A sixth-rounder drafted by the Rays back in 2010, the 35-year-old hurler made his debut with the Padres back in 2014 and enjoyed an impressive rookie campaign where he posted a 3.07 ERA in 73 1/3 innings spread between 12 starts and a pair of relief appearances. His 10.5% walk rate was a bit elevated, but he largely made up for it with a strong 22.9% strikeout rate to post solid results in line with those expected of a #4 starter.

Hahn was included by the Padres in an offseason trade with the A’s that sent catcher Derek Norris to San Diego, and his first year in Oakland saw the righty continue to fill the role of a potential mid-rotation arm with a 3.35 ERA and 3.51 FIP in 16 starts. Unfortunately, much of Hahn’s 2015 season was wiped out by a flexor tendon injury, and when he came back to the mound in 2016 he no longer looked like the same pitcher. The righty posted a lackluster 5.59 ERA in 116 innings of work for the A’s over the next two seasons before being traded once again, this time to the Royals in a trade that brought back reliever Ryan Buchter.

Hahn did not appear in the majors for the Royals until 2019 due to a UCL injury that eventually required surgery, and when he came back late in the 2019 season it was as a reliever. The right-hander ultimately made just 29 appearances for the Royals over parts of three seasons, with a 4.62 ERA (105 ERA+) and a 4.81 FIP in 25 1/3 innings of work. Hahn hit the injured list due to shoulder issues back in 2021 and didn’t pitch again professionally at any level until 2024, when he latched on with the Dodgers on a minor league deal. He’s thrown 51 1/3 solid innings for the Dodgers and Mariners at Triple-A since then, and now appears poised to make his comeback to the majors. He was released from his minor league deal with Seattle just a couple of weeks ago ahead of Opening Day, but evidently re-signed with the club on a fresh minor league deal since then.

Making room for Hahn on the active roster is Saucedo, who served as a solid middle relief option for Seattle in each of the past two seasons with a 3.54 ERA and 3.79 FIP in 86 1/3 innings of work across 105 outings. Things have not gone well for the southpaw so far this year, however, with four runs allowed and more walks than strikeouts in his first three appearances. He’ll head to Tacoma to serve as optionable depth for the Mariners for the time being as he awaits his next big league opportunity.

Mariners Designate Hagen Danner For Assignment

By Darragh McDonald | April 4, 2025 at 12:10pm CDT

The Mariners announced that right-hander Hagen Danner has been designated for assignment. That opens a 40-man spot for Luis F. Castillo. It was reported yesterday that Castillo would be coming up to start today’s game, making for an odd bit of trivia as the other Luis Castillo started the prior game for the M’s. An active roster spot was already opened by optioning left-hander Jhonathan Díaz yesterday.

Danner, 26, hasn’t been with the Mariners for long. He was claimed off waivers from the Blue Jays in January. He then tossed 3 1/3 innings in the Cactus League, allowing five earned runs. He was then sent to Triple-A Tacoma and started his season with 2 2/3 scoreless innings there.

His overall track record as a pitcher isn’t terribly long. The Jays drafted him as a catcher and tried him at that spot for a few years, but his bat didn’t pan out and they moved him to the mound. He has since put up some decent numbers on a rate basis but with occasional injury absences. Due to those health issues, he still hasn’t thrown 40 innings in any one season.

He has one third of an inning in the majors, which was back in 2023, and then 116 2/3 minor league innings from 2021 to the present. In that minor league work, he has a 2.93 earned run average, 28.3% strikeout rate and 8.7% walk rate.

The M’s will now have a week of DFA limbo to figure out what’s next. The waiver process takes 48 hours, so any trade interest would have to be gauged in the next five days. Danner still has an option, so he could be stashed in the minors by any club willing to give him a 40-man spot. If he were to pass through waivers unclaimed, the Mariners could hold onto him as some non-roster depth.
