Mariners Designate Jesse Hahn For Assignment

By | at

The Mariners announced that they have recalled right-hander Blas Castano to the big leagues, a move that was previously reported. Fellow righty Jesse Hahn has been designated for assignment as the corresponding move. The club’s 40-man roster count drops to 39.

Hahn, 35, seems to be following a similar trajectory to that of teammate Casey Lawrence. He finished the 2024 season on the Mariners’ Triple-A roster alongside Lawrence. Both have re-signed multiple minor league deals with the M’s since the conclusion of the 2024 campaign. Hahn has had two stints in the big leagues this year to Lawrence’s four, but he re-signed with the Mariners after electing free agency on the heels of his most recent DFA and could very well do so again.

Hahn’s five innings with the Mariners this year are his first big league work since a three-inning stint with the 2021 Royals. The right-hander has been beset by injuries throughout his big league career but has fought back onto the MLB periphery in the Pacific Northwest. Hahn has allowed three runs during his brief MLB look with the Mariners and has tossed five shutout innings in Tacoma.

If Hahn proves amenable to a similar setup to that of Lawrence — whom the Mariners outrighted earlier today — he could either accept an outright assignment or elect free agency and re-sign, assuming he clears waivers. Seattle would very likely call him to the majors a few more times this season, affording Hahn big league service time and pay, which clocks in at just under $4200 per day even at the minimum salary. (And, as a veteran with more than six years of service, he could well have a slightly higher base rate of pay in the majors.)

For now, the Mariners can trade Hahn or place him on waivers at any point in the next five days. Waivers are a 48-hour process, so we’ll know the outcome of his latest DFA within a week’s time.

Mariners Outright Casey Lawrence

By | at

The Mariners announced Friday that right-hander Casey Lawrence again passed through waivers following a recent DFA. He’s been assigned outright to Triple-A Tacoma.

Lawrence has the right to reject the assignment and elect free agency, although at this point, whether he chooses to do so seemingly has little bearing on his future with the organization. Lawrence has been designated for assignment by Seattle a whopping four times in the past six weeks — plus another time by the Blue Jays, who briefly claimed him from Seattle. (He elected free agency following that DFA and re-signed with the Mariners.) Each time, he’s returned to the Mariners.

In 2025 alone, Lawrence has had four stints with the Mariners, and there’s little reason to think it’ll stop there. He appears perfectly content to function as an effective 41st player on the 40-man roster, being selected to the roster whenever the big league club needs some extra length in the bullpen and then quickly being placed on waivers. The 37-year-old righty clearly has a good relationship with the organization and is comfortable in the Tacoma area, which is no surprise given that he also spent the entire 2024 season pitching for the Mariners’ Triple-A squad there.

Lawrence has pitched in six MLB games this year — five with Seattle, one with Toronto — and eaten up 17 2/3 innings in a long relief role. He’s logged a 4.08 ERA in that time, including a flat 3.00 mark in his 15 frames as a Mariner. He’s averaging just 88 mph on his fastball and carries a minuscule 8.8% strikeout rate, but Lawrence has also walked only one of the 80 men he’s faced (1.3%).

It’s not the smoothest way to earn a living, but by my count he’s picked up 23 days of major league service time this year. Even with a league-minimum split on the contracts he’s signing — and the Mariners are presumably compensating him a bit better than that — he’d have already earned a bit more than $96K in just big league salary, before factoring in any minor league pay. Assuming he has several more stints of this nature ahead of him, he’ll take home a fair bit more cash in 2025 than your standard mid-30s journeyman on the fringes of big league rosters, however unorthodox the road to that endgame may be.

Mariners To Promote Blas Castano

By | at

The Mariners are recalling right-hander Blas Castano from Triple-A Tacoma, reports John Brophy. The 26-year-old righty will be making his MLB debut when he first takes the mound. The team has not announced the move or any corresponding transactions. Castano is already on the 40-man roster — Seattle selected his contract last November to shield him from being taken in the Rule 5 Draft — so the M’s only need to make a 26-man roster move to accommodate their newest call-up.

Castano, 26, was originally signed out of the Dominican Republic by the Yankees back in 2018. They released him in the summer of 2023, after which he quickly signed a minor league pact with the Mariners. He’s since solidified himself as a prospect of some note in the system. Baseball America ranked him 23rd in a deep Mariners farm heading into the year.

Though he stands at an undersized 5’10” and 162 pounds, Castano has found some success in the upper minors. He split the 2024 season between Seattle’s Double-A and Triple-A affiliates, thriving at the former (3.31 ERA) but struggling a bit at the latter (5.13 ERA, albeit in a hitter-friendly league). It evened out to a 4.38 ERA, 20% strikeout rate and 8% walk rate in 125 1/3 innings — a strong enough showing that the Mariners clearly felt a pitching-needy organization might scoop him up if given the chance in the Rule 5 Draft.

This year, Castano has better run-prevention numbers but shakier rate stats in Tacoma. He’s posted a 3.43 ERA through 44 2/3 innings, but his strikeout rate has fallen from 23.3% to 15.5%, while his walk rate has jumped from 7.6% to 10.5%. He’s also plunked four batters in those 44 2/3 innings — including three in his most recent appearance. Despite clearly spotty command that day, he still held his opponents to a run through seven innings, however.

Castano’s primary pitch is a sinker that sits 93.1 mph this season, per Statcast. He’s complemented that offering with a slider that sits 82-83 mph, a changeup that sits 87-88mph, an 89 mph cutter to help neutralize lefties and a seldom-used four-seamer that sits in the same velo range as his sinker. Baseball America’s scouting report notes that Castano’s changeup is his best secondary offering when it’s working and calls the righty a potential fifth starter or a “do-everything swingman” who can pitch in a wide variety of roles.

Mariners relievers Jesse Hahn and Eduard Bazardo threw 28 and 30 pitches yesterday, respectively, and their scheduled starter is right Emerson Hancock, who’s pitched just 9 2/3 innings across his past two starts. They could want a fresh arm to give them some length in the event of another relatively short start from Hancock, or it’s possible Castano could get a spot start if the Mariners decide to shuffle up their rotation this weekend for any reason.

Mariners Activate George Kirby For Season Debut

By | at

The Mariners announced Thursday that right-hander George Kirby has been reinstated from the injured list. He’ll make his 2025 debut today against the Astros. Righty Troy Taylor was optioned to Triple-A Tacoma last night to open a spot on the roster for Kirby’s return.

The first-place Mariners have surged to a 28-20 record this season despite not getting a single pitch from arguably their best starter. The 27-year-old Kirby has been out all season after the Mariners opted for a cautious approach when Kirby was diagnosed with shoulder inflammation during spring training.

A first-round pick back in 2019 (No. 20 overall), Kirby quickly became one of the Mariners’ top pitching prospects and was soon regarded as one of the top prospects in the entire sport. He breezed through the minors and could very well have debuted even sooner were it not for the canceled 2020 minor league season.

Kirby broke through to the majors in 2022 and hasn’t looked back. He pitched 130 innings over the life of 26 starts in his rookie season and turned in a 3.39 ERA with a 24.5% strikeout rate and 4.1% walk rate. Few pitchers can sustain a walk rate that low, but Kirby has actually improved upon that mark in subsequent seasons. He was touted as having the best command of perhaps any top pitching prospect in the sport prior to his debut, and he now has a legitimate claim to the best command of any pitcher in Major League Baseball.

Since his 2022 debut, no starting pitcher has a lower walk rate than Kirby’s 3.1% mark. Only one qualified reliever in that time has a better walk rate (Chris Martin, at 2.8%). You’d have to drop the threshold to a minimum of 20 innings pitched (total) since 2022 to find a second pitcher with a lower walk rate than Kirby.

Kirby’s pinpoint command is all the more deadly when one considers that he’s not the archetypal soft-tossing, finesse pitcher typically associated with this type of precision. He’s averaged 95.8 mph on his four-seamer in his career and sat 96.1 mph with the pitch from 2023-24.

Kirby was an All-Star in 2023 and finished sixth in AL Cy Young voting that season. He’s started 89 big league games for the Mariners since his debut and touts a 3.43 ERA, 23.3% strikeout rate and 43.4% ground-ball rate to go along with that pristine walk rate. Those strikeout and grounder rates are only a bit better than average, but a pitcher who averages less than a walk per start doesn’t need to pile up strikeouts or ground-balls at league-leading rates to be among the most effective pitchers in the sport.

The Mariners are getting Kirby back at an ideal time. Rotation-mates Logan Gilbert (flexor strain) and Bryce Miller (elbow inflammation) are both on the 15-day injured list at the moment. Seattle is also set to square off against the second-place Astros for a four-game series. Houston has been a league-average team against right-handed pitching this season, and the ’Stros are currently without their top left-handed bat: designated hitter Yordan Alvarez (though he has uncharacteristically struggled versus righties this season). The only left-handed hitters on Houston’s roster are switch-hitting catcher Victor Caratini and backup catcher Cesar Salazar. Kirby held right-handed hitters to an awful .234/.257/.360 slash in 2024.

Jean Segura Retires

By | at

Longtime MLB infielder Jean Segura has retired, according to a social media post from his representatives at CAA. Segura last appeared in the majors in 2023 and spent time in Triple-A with the Orioles last season.

Segura had an accomplished 12-year big league run. The Dominican Republic native signed as an amateur with the Angels in 2007. He was one of the sport’s top prospects when he debuted with the Halos in July 2012. Segura played one game, then was traded to Milwaukee less than a week later as the centerpiece of the prospect package for Zack Greinke.

The Brewers immediately installed Segura as their starting shortstop. He held that role for the next three and a half seasons. His first full season was his best in Milwaukee, as he hit .294 to earn an All-Star selection. His production plummeted between 2014-15. The Brewers moved on before the ’16 season, moving him to the Diamondbacks in a deal for starter Chase Anderson and minor league second baseman Isan Díaz.

Segura only spent one season in the desert, but it was the best year of his career. He led the National League with 203 hits while posting a .319/.368/.499 line over 694 plate appearances. He set personal highs in all three slash stats. He tallied a career-high 41 doubles and hit 20 home runs for the only time. FanGraphs and Baseball Reference each credited him with over six wins above replacement.

Fantastic as Segura’s season was, his greatest impact on the Arizona organization came the following winter. They packaged him alongside Mitch Haniger to Seattle for Ketel Marte and Taijuan Walker. Marte is on track to spend over a decade with the Snakes and has become one of the best players in franchise history.

The Mariners signed Segura to a five-year, $70MM extension midway through his first season in the Pacific Northwest. He would only spend one year of that contract in Seattle, though he remained an above-average regular during his time there. He hit .300 or better in both years and slashed .302/.345/.421 in nearly 1200 plate appearances overall. He was on the move again during the 2018-19 offseason. The M’s dealt him to Philadelphia in a deal that netted J.P. Crawford.

The move worked out well for both clubs. Crawford has developed into Seattle’s long-term answer at shortstop. Segura was a solid regular over four seasons with the Phils — first at shortstop, then for three seasons at second base. He hit .281/.337/.418 in 427 games in a Philadelphia uniform. It was his second-longest run with one team, trailing his early-career stint in Milwaukee. It also afforded him the only playoff experience of his career. Segura was a regular throughout the Phils’ pennant run in 2022, though he hit .214 in 17 postseason games.

Philadelphia bought out Segura’s $17MM club option for the 2023 season. That sent him to the free agent market for the first time. He signed a two-year, $17MM contract with the Marlins to move to third base. The deal did not pan out, as he hit .219/.277/.279 across 85 games for the Fish. They traded him to the Guardians in a salary swap for Josh Bell at the ’23 deadline. Cleveland immediately released him, and Segura’s final game as a Marlin turned out to be his last in the big leagues.

While his last season didn’t go well, Segura can look back on a very good major league career. He finishes with a .281/.327/.401 batting line in more than 1400 games. He topped 1500 hits, connected on 110 home runs, and stole 211 bases. Segura drove in 513 runs and scored 737 times. He hit .300 on three occasions, made a pair of All-Star Games, and received down-ballot MVP votes for his year in Arizona. Baseball Reference calculates his lifetime earnings close to $106MM. He was a part of five notable trades, two of which remain consequential today. MLBTR congratulates Segura on his run and wishes him the best in his post-playing days.

Mariners Designate Casey Lawrence For Assignment, Select Jesse Hahn

By | at

The Mariners announced that they have designated right-hander Casey Lawrence for assignment. Fellow righty Jesse Hahn has been selected to the roster in a corresponding move. Bob Condotta of The Seattle Times reported the moves prior to the official announcement.

MLBTR readers should not be surprised to see Lawrence bumped off the roster again. The Mariners selected his contract yesterday, the fourth time this year they have done so. In each instance, Lawrence pitched in a game or two before being designated for assignment. The first two resulted in him clearing waivers, electing free agency and re-signing with the M’s on a new minor league deal. The third time they put him on waivers, the Blue Jays claimed him. That club also used him once before putting giving him the DFA treatment. That led Lawrence back to the Mariners on yet another minor league deal.

Yesterday, Lawrence served as the bulk pitcher in a bullpen game, which was necessary due to rotation injuries. The M’s have had George Kirby and Logan Gilbert on the injured list for a while and Bryce Miller recently joined them. That leaves them with a four-man rotation core of Luis Castillo, Bryan Woo, Logan Evans and Emerson Hancock.

Yesterday, Casey Legumina officially started the game but went just one inning as an opener. Lawrence then came in and tossed five innings, allowing one earned run. That was enough for a tough-luck loss as the M’s fell to the White Sox 1-0.

Based on the circumstances, it always seemed likely that Lawrence would be bumped off the roster yet again and that has indeed come to pass. Per Condotta, Kirby will be reinstated from the IL to start tomorrow’s game, bringing the M’s back to a five-man rotation.

Lawrence will be placed on waivers again in the coming days. Based on recent history, it’s fair to assume that he will clear and then return to the M’s on another minor league deal. Though it’s also possible that some club in need of a fresh arm puts in a claim, as the Jays did a few weeks back. After yesterday’s outing, Lawrence now has a 4.08 earned run average in 17 2/3 innings on the year. He has a career ERA of 6.42 in 141 2/3 innings spread over five seasons.

Hahn, 35, gets a roster spot for now. In a similar situation to Lawrence, he had his contract selected earlier this year but made just two appearances before being designated for assignment. He logged four scoreless innings in those appearances before getting the DFA treatment. He cleared waivers, elected free agency and re-signed with the M’s on another minor league deal. Shortly after re-signing, he landed on the minor league injured list but he has evidently returned to health. He’s made four scoreless Triple-A appearances in the past two weeks.

The M’s will need to open an active roster spot for Kirby’s activation tomorrow. Perhaps Hahn is slated for a short stay but they could also opt to send down Troy Taylor, who has options and is struggling, with a 12.15 ERA so far.

Hahn has a 4.17 career ERA in 315 1/3 big league innings but this is his first season with major league work since 2021. A shoulder injury cost him the 2022 and 2023 seasons and then he was stuck in the minors last year. As mentioned, he’s been putting up zeroes so far in 2025 but in a small sample.

Mariners Select Casey Lawrence, Designate Austin Shenton For Assignment

By | at

The Mariners announced that they have selected the contract of right-hander Casey Lawrence. Left-hander Jhonathan Díaz was optioned to Triple-A Tacoma in a corresponding active roster move. To open a 40-man spot for Lawrence, infielder Austin Shenton has been designated for assignment. Brady Farkas of Refuse to Lose was among those to relay last night that Lawrence was likely to be called up today.

Lawrence, 37, has been on and off the Mariners’ roster all year long. He signed a minor league deal with Seattle in the offseason and this is the fourth time they have selected him to the roster. In the first two instances, he was quickly designated for assignment after an appearance or two. He elected free agency after clearing waivers and returned to the club on a fresh minor league deal. His third DFA resulted in him being claimed by the Blue Jays. That club gave him similar treatment, putting him into one game before sending him into DFA limbo. Lawrence again elected free agency and returned to the M’s on a fresh minor league deal, leading to today’s selection.

Around all those transactions, he has 12 2/3 innings in five appearances. He has a 4.97 earned run average, 8.3% strikeout rate, 1.7% walk rate and 45.3% ground ball rate. He now has a 6.59 career ERA in 136 2/3 innings, spread over five different seasons.

The Mariners recently put Bryce Miller on the 15-day injured list, joining George Kirby and Logan Gilbert. That leaves them with a four-man rotation core of Luis Castillo, Bryan Woo, Emerson Hancock and Logan Evans. When Miller hit the IL about a week ago, Díaz was recalled to give the club a fresh arm capable of covering multiple innings, but he hasn’t been used since. His last outing was a minor league game on May 9th, 11 days ago.

Lawrence last pitched on the farm May 15th. That was only for two innings, but it seems the Mariners felt better about him on regular rest as opposed to Díaz after such a long layoff. Casey Legumina is listed as tonight’s starter but he will probably serve as an opener, as he’s mostly been a one-inning guy this year. After that, the M’s will see what they get from Lawrence as part of a bullpen game.

To get Lawrence onto the big league roster, the M’s are risking losing Shenton. The 27-year-old infielder was acquired from the Rays in a November cash deal. He’s out to a slow start this year. He has stepped to the plate 169 times at the Triple-A level. He has eight home runs but has been punched out at a 29% clip. He has a .207/.284/.413 line and 76 wRC+ on the year.

That rough performance has nudged him off the 40-man and into DFA limbo, which can last for as long as a week. However, the waiver process takes 48 hours, so the Mariners will have a maximum of five days to explore trade interest.

It’s possible that some other club looks beyond the rough 2025 numbers to see potential. Over the 2023 and 2024 seasons, Shenton took 940 minor league plate appearances. His 28.1% strikeout rate in those was certainly high but he also drew walks at a huge 15.1% clip and hit 49 home runs. He produced a combined slash line of .286/.399/.549 in that time, leading to a 149 wRC+.

For his minor league career, Shenton has mostly played the infield corners, with some brief looks at second base and in the outfield corners as well. He has less than a year of service time and is still optionable for the rest of this year and one additional season. Put it all together and it’s possible some club will be enticed to acquire him as a depth piece.

Kolten Wong Announces Retirement

By | at

Veteran infielder Kolten Wong announced his retirement from professional baseball earlier today at his alma mater, University of Hawaii, as relayed by Brian McInnis of Spectrum News. Wong was in town to throw out the first pitch at a game against UC San Diego.

“Pretty much right now, I’m done,” Wong said, as relayed by McInnis. “I’ve kind of come to the conclusion that I’m probably going to be hanging them up. It’s just one of those things where, the game how it’s going now, there’s no sense of chasing (it). … I’m a dad now, yes, I’m enjoying that. I’m trying to be the best big league dad that I can be. So I’m going to stick to that.”

A veteran of 11 MLB seasons, the 34-year-old Wong was drafted 22nd overall by the Cardinals back in 2011. He made his way to the majors for a brief cup of coffee just two years later, but his big league career began in earnest during the 2014 season. That year, Wong appeared in 113 games for the Cardinals and finished third in NL Rookie of the Year voting behind Jacob deGrom and Billy Hamilton after slashing .249/.292/.388 in 433 trips to the plate while playing second base exclusively for St. Louis. Wong would go on as a roughly average regular with the Cards for a few years, getting a brief look in the outfield during the 2016 season to accommodate occasional reps at the position for Matt Carpenter and Jedd Gyorko but otherwise remaining locked in as the club’s everyday second baseman thanks to nearly average offense (92 wRC+) and fantastic defense at the keystone.

Wong enjoyed something of a breakout during his age-26 season with the Cardinals in 2017, as he slashed .285/.376/.412 with a 108 wRC+. It was his best offensive season to that point in his career, and while injuries limited him to just 108 games that year he would turn in above average results overall at the plate from the start of that season onward. That was a fortuitous step forward for the Cardinals, seeing as it came in just the second year of a five-year, $25.5MM extension the sides agreed to prior to the 2016 season. Wong hit a combined .273/.356/.398 (104 wRC+) while playing stellar defense over the course of his final four years in St. Louis, even earning Gold Glove awards for his work at second base during the 2019 and 2020 seasons.

Aside from that solid regular season production, Wong departed St. Louis with a solid postseason resume, having slashed .206/.243/.464 with five homers, four stolen bases, eight doubles, and a triple in 104 postseason plate appearances for the Cards. The Cardinals ultimately declined Wong’s 2021 club option and allowed him to test free agency in order to create an everyday spot in the lineup for utility man Tommy Edman. Wong eventually signed with the Brewers on a two-year, $18MM guarantee that came with a club option for the 2023 season. Wong’s defensive numbers took a step back during his time in Milwaukee as he entered his age-30 season, but his offense was better than ever as he hit a strong .262/.337/.439 (113 wRC+) across his two campaigns with the club.

Unlike the Cardinals before them, the Brewers did pick up his third year club option. With that being said, he still found himself in another uniform prior to the 2023 campaign as he was traded to the Mariners in a deal that brought Jesse Winker and Abraham Toro to Milwaukee. It’s a deal that didn’t work out for anyone, as none of those players were particularly effective for their new clubs. Wong struggled mightily during his time in Seattle, hitting just .165/.241/.227 across 67 games before he was released in early August.

Wong signed with the Dodgers on a minor league deal shortly thereafter, however, and managed to end his big league career on a high note as he slashed an impressive .300/.353/.500 (129 wRC+) over 20 games in Los Angeles before participating in the NLDS with the club. Headed into 2024, Wong signed briefly with both the Orioles and the Diamondbacks on minor league deals. He hit .271/.339/.383 in 121 trips to the plate for Arizona’s Triple-A affiliate in Reno before being granted his release just under a year ago. He’s not played in affiliated ball since, and after going unsigned this offseason Wong has evidently decided to put his playing career behind him.

In all, Wong wraps his MLB career with a .256/.330/.390 career slash line, good for a roughly league average 97 wRC+. That triple slash comes across 1189 games and encapsulates a career that saw him collect 973 hits, 303 extra-base hits, 511 runs scored and 405 runs batted in. In addition to his aforementioned two Gold Glove awards and status as a Rookie of the Year finalist, Wong also received down-ballot consideration for the NL MVP award during the 2019 season. MLB Trade Rumors congratulates Wong on a fine career, and wishes him all the best in whatever comes next.

The Mariners Need To Shake Up Their Offense

By | at

Mariners fans entered the season with something of a sour outlook on the 2025 season. That's understandable, given an offseason in which the front office was clearly handcuffed by payroll limitations and a paper-thin trade market for big league hitters. Armed with a only a reported $15-16MM to patch over multiple needs in the infield, there wasn't a lot out there for president of baseball operations Jerry Dipoto and general manager Justin Hollander to realistically pursue.

Seattle wound up rolling the dice on a handful of cost-effective infield options. Jorge Polanco returned on a one-year deal with a conditional player option. Donovan Solano snagged a $3.5MM guarantee. Rowdy Tellez signed a minor league deal and made the team after a big spring showing (.298/.320/.574 in 50 plate appearances).

Frustration was understandable. The Mariners had made a big splash at the prior deadline, reeling in Randy Arozarena from the Rays, but fans hoping for a similarly bold strike in the offseason after another narrow playoff miss were left wanting.

That frustration likely faded for many as the Mariners raced out to a blistering start. On May 7, they sat with a 22-14 record, leading the American League West by a three-game margin and sporting a +31 run differential. One might imagine that the Mariners were again being carried by their brilliant rotation, but that wasn't the case -- at least not entirely. George Kirby has still yet to throw a pitch in 2025 as he recovers from some shoulder inflammation. Logan Gilbert hit the injured list on April 25 and remains there. Bryan Woo has been brilliant. Luis Castillo has been good. Gilbert was his typically excellent self prior to his flexor injury. But the Mariners' starting pitching, as a whole, has been a middle-of-the-pack unit.

Instead, Seattle's hot start was largely attributable to a surprisingly potent offense. Through that previously mentioned May 7 date, M's hitters were slashing .247/.340/.415, resulting in a 122 wRC+ that ranked third in the majors. They were fourth in home runs, seventh in runs scored, 12th in batting average, second in on-base percentage and ninth in slugging percentage.

In the week-plus since that time, the Mariners have lost five of six games and posted a collective .206/.259/.326 batting line (70 wRC+). Typically, there's little sense panicking over a week of poor results, but there was already reason to be a bit skeptical of Seattle's sudden offensive prowess. Good as Cal Raleigh is, he's not going to continue at a 50-homer pace. Polanco isn't going to keep his OPS north of 1.000. J.P. Crawford isn't sustaining a .410 OBP, nor will Leo Rivas keep hitting .341. Those timely early-season hot streaks buoyed the Seattle offense but can't all be sustained.

The Mariners seemingly recognize that some new blood is needed; they claimed Leody Taveras off waivers from the division-rival Rangers and took on about $3.7MM in salary to do so. That was an understandable move with both Victor Robles and Luke Raley on the injured list for the foreseeable future, but it shouldn't be the only one the Mariners consider.

Let's run through a few easy ways to bolster a lineup that is facing even more pressure than usual now that Bryce Miller has joined rotation-mates Kirby and Gilbert on the injured list...

Mariners Place Bryce Miller On IL With Elbow Inflammation

By | at

1:00pm: Miller spoke to reporters, with video relayed by Adam Jude of The Seattle Times. He revealed that he had a cortisone shot and said that an MRI showed no structural damage. He’s hoping to return after a minimal IL stint.

11:50am: The Mariners announced today that right-hander Bryce Miller has been placed on the 15-day injured list, retroactive to May 12th, due to right elbow inflammation. Left-hander Jhonathan Díaz has been recalled to take his place on the roster.

The club hasn’t yet provided any updates on the severity of Miller’s injury or how long they expect him to be out, but it’s always worrisome when a pitcher’s throwing elbow is injured. His most recent start was against the Blue Jays on Sunday, which did not go well, as he allowed seven earned runs in five innings.

Afterwards, he spoke of some physical issues he’s been battling this season but without getting too specific, alluding to some arm soreness and back tightness. “In the past, it felt like I could get through six innings, it’s a breeze,” Miller said, per Daniel Kramer of MLB.com. “I’d feel as good as I do in the sixth as I did in the first. And it’s been a struggle to have that feeling so far. So I don’t know. We’re going to work on it.” Though he didn’t provide many details, Miller continued: “I’ve had multiple things that kind of have lingered since, really, the end of last season, and I kind of took them through the offseason. I thought that I’d be feeling good, and I haven’t felt like myself, body-wise and physically. I think that’s led to being more on my heels mentally, and it just kind of snowballed.”

Miller’s velocity is down a bit compared to last year. He averaged 95.2 miles per hour on his fastball in 2024 and was in that range for much of the early parts of the season as well. So far this year, he’s down to 94.4 mph. Most of his other pitches are down a tick or two as well.

As Miller alluded to, getting deeper into games has been an issue. He hasn’t yet gone six frames in a start this year. His first two outings were his only two going more than five innings. Last year, he went seven innings seven times and six or above an additional 13 times.

The righty is currently sporting a 5.22 earned run average on the year, a big jump from last year’s 2.94 ERA. His 20.1% strikeout rate is a few points below last year’s 24.3% mark, while his walk rate has almost doubled from 6.4% to 12.1%.

Perhaps the physical issues provide a partial explanation for the declining results, but it’s still an unpleasant development for the M’s, who are already dealing with a depleted rotation. George Kirby has been on the IL all season so far due to shoulder inflammation. Logan Gilbert followed him to the IL in late April, suffering from a flexor strain in his pitching elbow.

The Mariners were hoping to start the season with an elite rotation consisting of Miller, Kirby, Gilbert, Bryan Woo and Luis Castillo. That was such a talented group that trade rumors swirled around them all winter. The Seattle front office downplayed the possibility of a trade and is surely glad that they resisted the temptation to flip pitching for more offense, as they are now without three of their projected starting five.

Kirby has been on a rehab assignment and is expected to make one more appearance in the minors before rejoining the major league club next week. Gilbert is perhaps a bit behind Kirby, though he did throw a bullpen yesterday, per Kramer.

For the time being, the Mariners will proceed with a rotation consisting of Castillo, Woo, Logan Evans and Emerson Hancock. Castillo is starting today’s game and then the club is off tomorrow. Díaz can perhaps make a spot start or serve as a long reliever out of the bullpen. That might be a short stay with Kirby due back soon, but both Evans and Hancock currently have ERAs at 6.60 or above, so perhaps one of them could get bumped out instead.
