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.

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.

Mariners Select Jhonathan Díaz

By | at

The Mariners announced that they have selected the contract of left-hander Jhonathan Díaz. The club already had an open 40-man roster spot, so no corresponding move was necessary there. In terms of the active roster, right-hander Emerson Hancock has been optioned to Triple-A Tacoma. Daniel Kramer of MLB.com noted earlier that Díaz was in the clubhouse with Hancock headed out.

As of a month ago, the Mariners were set to open the season with a strong front five of Logan Gilbert, Bryce Miller, George Kirby, Bryan Woo and Luis Castillo. Unfortunately, Kirby was shut down in early March due to some shoulder inflammation and started the season on the injured list.

That opened an opportunity for Hancock but his start in yesterday’s game against the Tigers could hardly have gone much worse. He didn’t make it out of the first inning, recording just two outs, one of which was a caught stealing. He allowed six earned runs on seven hits, forcing the bullpen to cover 8 1/3 innings.

Of the club’s eight relievers, four of them pitched last night, each of them recording at least four outs and throwing at least 31 pitches. Out of the four guys who didn’t pitch last night, three of them appeared in Sunday’s contest.

They have brought up Díaz presumably for a multi-inning option out of the bullpen soon. Last year, he made five appearances in the majors for Seattle but spent most of his time in the Triple-A rotation. He logged 117 2/3 innings for Tacoma over 22 starts and one relief appearance. His 4.36 earned run average wasn’t bad in the context of the hitter-friendly Pacific Coast League. He struck out 22.9% of batters faced, gave out walks at a 9.9% clip and got grounders on 54.1% of balls in play.

The lefty was outrighted off the roster in February and elected free agency but returned via a minor league deal. He still has options, so the M’s could perhaps shuttle him to Tacoma and back throughout the year, recalling him whenever a situation like this arises.

In the short term, it’s unclear what the M’s plan to do with the rotation. They are in the midst of a seven-game stretch to start the season, with two more to go. But thanks to having five off-days in April and some at the start of May, they don’t play more than six games in a row again until the second half of May. Perhaps they could survive for a while with a four-man group of Gilbert, Miller, Woo and Castillo. Optionable arms like Hancock, Díaz and Blas Castano could perhaps make spot starts or take bulk work in occasional bullpen games over the next six weeks or so.

Mariners Re-Sign Jhonathan Diaz To Minor League Deal

By | at

The Mariners have re-signed lefty Jhonathan Diaz to a minor league contract, reports Ryan Divish of the Seattle Times. He’s already in camp and will be a non-roster invitee this spring.

Diaz was designated for assignment earlier this month. The M’s ultimately placed him on waivers, and the southpaw rejected an outright assignment in favor of free agency upon going unclaimed. He’s now back with the Mariners to vie for a job in camp or, likelier, to head to Triple-A Tacoma as a depth option early in the event of injuries in the big league rotation.

The 28-year-old Diaz has pitched in parts of four big league seasons — from 2021-23 with the Angels and with the Mariners in 2024. He’s totaled 45 MLB frames and carries a pedestrian 4.80 earned run average in that time. The soft-tosser has fanned just 15% of his big league opponents against an unsightly 12.6% walk rate, though his 45.7% ground-ball rate and 0.80 HR/9 mark are both solid.

While the Mariners didn’t need to lean on in-house rotation depth much in 2024 thanks to good health from Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller and (to a lesser extent) Bryan Woo, Diaz still provided them a decent option in the upper minors. He started 22 games in Triple-A Tacoma and tallied 117 2/3 innings with a 4.36 ERA there. Diaz’s strikeout and walk rates in the majors have been ugly, but he whiffed 22.9% of his opponents in Tacoma last year against a 9.9% walk rate. That’s a roughly average strikeout rate and a still worse-than-average walk rate, but both are a far sight better than his MLB rates.

Diaz probably won’t be the first man up in the event of a rotation injury. Former No. 6 overall pick Emerson Hancock was the most frequently called upon reserve last year, and Seattle added righty Blas Castano to the 40-man roster earlier this winter. Top prospect Logan Evans and journeyman Casey Lawrence are also non-roster invitees this spring and could land in the Tacoma rotation to begin the year. Diaz will be in the mix though, especially if the Mariners at any point find themselves in need of multiple starters.

Jhonathan Diaz Elects Free Agency

By | at

The Mariners announced a pair of DFA resolutions this evening. Outfielder Cade Marlowe and left-hander Jhonathan Díaz each went unclaimed. Díaz elected free agency, while Marlowe will stick in the organization without occupying a 40-man roster spot.

Díaz lost his roster spot when Seattle acquired Casey Legumina from the Reds. The 28-year-old southpaw had been on the roster since Seattle selected his contract in late May. They kept him on optional assignment to Triple-A Tacoma for most of the year. Diaz made five big league appearances, including one start. He allowed six runs (five earned) over 9 2/3 innings, striking out eight while issuing three walks.

Before his Seattle tenure, Díaz spent parts of three seasons with the Angels. He has yet to reach 20 major league innings in a season. Over 45 career frames, Díaz has a 4.80 earned run average with a below-average 15% strikeout percentage and a lofty 12.6% walk rate. The Venezuelan-born southpaw is coming off a solid year in Tacoma. Díaz put up a 4.36 ERA with a near-23% strikeout rate and a strong 54.1% grounder percentage across 23 appearances. He only averaged 89-90 MPH on his fastball, but the Triple-A numbers will surely get him another minor league opportunity somewhere.

Díaz had the right to choose free agency because he’d been outrighted by the Angels in 2023. This is Marlowe’s first career outright, so he had no choice but to accept the minor league assignment. The 27-year-old has appeared in 42 MLB games over the past two seasons. Marlowe had a middling year with Tacoma, hitting .236/.342/.395 over 411 trips to the plate. He was designated for assignment as the corresponding move for the finalization of the Jorge Polanco deal. The Mariners figure to extend him a non-roster invitation to MLB camp later this month.

Mariners Acquire Casey Legumina, Designate Jhonathan Díaz

By | at

The Mariners announced that they have acquired right-hander Casey Legumina from the Reds. Cincinnati, who designated Legumina for assignment last week when they signed Austin Hays, receives cash considerations in return. The M’s have designated left-hander Jhonathan Díaz for assignment in a corresponding move.

Legumina, 28 in June, has a limited major league track record to this point. He threw a combined 22 innings for the Reds over the past two seasons, allowing 17 earned runs for an unpleasant 6.75 ERA. His 16.7% strikeout rate and 10.2% walk rate in that time have both been below average, though his 56.4% ground ball rate has been strong.

The M’s are probably more interested in his larger sample of minor league work. Over the past four years, he has logged 226 2/3 innings on the farm with a 4.05 ERA, 26% strikeout rate and 8.5% walk rate. He did a decent amount of starting earlier in his career but has primarily been working in relief over the past two seasons.

He still has one option year remaining and less than a full season of service time. That means he can be shuttled between the majors and the minors pretty freely for one more year and can also be cheaply retained well into the future if he continues to hang onto a roster spot. The M’s apparently had enough interest in Legumina as a depth arm that they sent some cash to the Reds in order to skip the waiver line.

Díaz, 28, also has a small big league résumé. He has thrown 45 innings in the majors, scattered across four different seasons. He has a 4.80 ERA, 15% strikeout rate, 12.6% walk rate and 45.7% ground ball rate.

Naturally, the minor league numbers are better, and in a larger sample. Over the past four years, he has thrown 328 innings on the farm, most of that coming in the hitter-friendly Pacific Coast League. He has a 4.42 ERA in that time, along with a 23.6% strikeout rate, 9.4% walk rate and grounders on about half of the balls in play he allowed.

Díaz still has a couple of options and could perhaps appeal to a club looking for some affordable rotation depth. The M’s will have a maximum of one week of DFA limbo to figure out what’s next for the lefty, though the waiver process takes 48 hours, so any trade talks would need to happen in the next five days.

Mariners Select Seby Zavala, Sign Chris Devenski

By | at

The Mariners announced that they have selected the contract of catcher Seby Zavala, with left-hander Jhonathan Díaz optioned to Triple-A Tacoma in a corresponding move. Additionally, the M’s have signed right-hander Chris Devenski to a major league contract, though Devenski will report to Tacoma. Seattle had three vacancies on their 40-man roster coming into today, so their count is now at 39.

Zavala, 30, was acquired as part of the Eugenio Suárez trade back in November. He was used as a glove-first backup catcher for a while with Cal Raleigh getting the bulk of the playing time. The M’s had also signed Mitch Garver but with the idea of using him primarily as a designated hitter, though Garver started playing behind the plate more as the season wore on.

That left just 43 plate appearances for Zavala through the middle of June. He hit .154/.214/.282 in that limited time while striking out at a 37.2% rate. As Garver started donning the tools of ignorance, Zavala was designated for assignment and outrighted off the roster. He had the right to elect free agency at that time but stuck with the M’s and is now back in the bigs.

His selection is likely due to Garver’s status, as he was hit by a pitch on his right wrist on Sunday. He was catching that game with Raleigh in the DH slot, but Raleigh moved behind the plate in the third inning as Garver departed, leaving the M’s to play without a DH for the rest of the game.

Per Daniel Kramer of MLB.com on X, Garver is feeling better but still sore and is “going to go feel it out,” in Garver’s words. Since he is seemingly unavailable, at least for a few days, the club was going to be left with just Raleigh and no backup catcher, which prompted Zavala’s return. Once Garver is healthy, Zavala might get squeezed out again since he is out of options.

Devenski, 33, was just released by the Rays last week but has quickly landed a new gig. As a veteran with more than five years of service time, he can’t be optioned to the minors without his consent. Since the M’s announced that he will report to Tacoma, perhaps he has given his consent, unless that’s just an on-paper move until he reports to the club.

The righty was having a rough season with the Rays, tossing 26 2/3 innings with 6.75 earned runs allowed per nine. His 19.7% strikeout rate and 11.5% walk rate were both below average, leading Tampa to cut him loose.

The M’s clearly have some kind of idea for getting him back on track. He was once a dominant reliever with the Astros, throwing 189 innings with that club over 2016 and 2017 with a 2.35 ERA, 28.2% strikeout rate and 6.4% walk rate. But he struggled in the following years and missed time due to injuries, including Tommy John surgery. He had a 4.56 ERA over 2018 and 2019 and then a 9.47 ERA from 2020 to 2022.

He seemed to show a bit of life last year, with 42 1/3 innings between the Angels and Rays. He had a 4.46 ERA in that time, as well as a 24.3% strikeout rate and 6.4% walk rate. The Rays were encouraged enough to bring him back for 2024 with a $1.1MM guarantee, in the form of a $1MM salary this year and $100K buyout on a 2025 option.

But now that Devenski has been released, the Rays are left on the hook for that money. The M’s will only owe him the prorated version of the major league minimum for any time spent on the roster, with that amount subtracted from what the Rays pay.

The M’s have taken some hits in their bullpen this year, with each of Matt Brash, Gregory Santos, Jackson Kowar and Gabe Speier currently on the injured list, with Brash and Kowar done for the year due to Tommy John surgery. There’s little harm on taking a low-cost flier on Devenski to see if he can help make up for those losses by returning to form.

Mariners Outright Kirby Snead

By | at

TODAY: The Mariners announced that Snead has cleared waivers and been outrighted to Triple-A.  As was reported yesterday, Bowman also cleared waivers and chose free agency rather than accept an outright assignment.

JUNE 11: The Mariners announced that they have recalled left-hander Jhonathan Díaz and right-hander Eduard Bazardo from Triple-A Tacoma. Díaz will start tonight’s game instead of Bryan Woo. To open roster spots for those two arms, both right-hander Matt Bowman and left-hander Kirby Snead have been designated for assignment.

Snead, 29, signed a minor league deal with the Mariners in the offseason. He made 12 appearances for Triple-A Tacoma to start the year with a 2.92 earned run average. He struck out 27.7% of batters faced, gave out walks at a tiny 4.3% rate and got grounders on 63.3% of balls in play.

That got him called up to the majors just over a month ago but the results haven’t been as strong since then. He made 11 appearances for the Mariners with a 4.35 ERA. His 51.5% ground ball rate was still strong but his strikeout and walk tallies were both seven, giving him a subpar 14.6% rate in each of those categories.

Snead pitched in two of the past three games for Seattle and likely would have been down for a day or two. Since he’s out of options and the overall results have been mediocre, he’s been bumped off the roster as the club gets some fresh arms aboard.

Bowman, 33, is also out of options and has been featured in many transactions because of it. The M’s just added him to their roster on Sunday and he made one appearances for them, logging two thirds of an inning in last night’s contest. That’s already the third team he’s pitched for this year, also taking the mound for the Twins and Diamondbacks.

For each player, the Mariners will have one week to either line up a trade or pass them through waivers. Bowman has a 4.22 ERA in 200 1/3 career innings but most of that work was a long time ago. He didn’t pitch in the majors during the 2020-2022 seasons due to injuries, including Tommy John surgery. He returned to the bigs by tossing four innings with the Yankees last year. Overall, he’s been able to get decent amounts of ground balls, with 55.6% of balls in play in his career hitting the dirt. Snead has a career ERA of 5.09 in a more limited sample of 74 1/3 innings at the major league level.

Díaz, 27, signed a minor league deal with the Mariners in the offseason and has been posting great results for Triple-A Tacoma this year. In 12 outings, including 11 starts and one long relief outing, he has thrown 66 1/3 innings with a 2.98 ERA. That’s despite pitching in the hitter-friendly confines of the Pacific Coast League. He has a 24.3% strikeout rate, 5.8% walk rate and 57.1% ground ball rate in that time.

He had an opt-out on his minor league deal but the Mariners were clearly impressed by his work in Tacoma this year. They added him to their 40-man roster to prevent him from triggering that opt-out, but kept him on optional assignment until today.

Per Adam Jude of the Seattle Times on X, Woo is having an MRI on his arm. It’s unclear exactly what the issue is but Woo began the year on the injured list due to right medial elbow inflammation. He returned in early May and has been utterly dominating, with an ERA of 1.07 in his six starts this year.

It’s a concerning development for the Mariners, both due to how well Woo has been pitching and the fact that it may be a recurrence of the previous issue. Further updates may be forthcoming after the MRI results come in, but it seems Díaz will step in and make at least one spot start. The Mariners have a strong rotation with Luis Castillo, Logan Gilbert, George Kirby and Bryce Miller in four spots, even without Woo. If Woo needs a trip to the IL, perhaps Díaz will stick around, though the M’s also have Emerson Hancock on the 40-man roster.

Mariners Select Jhonathan Díaz

By | at

The Mariners announced that they have selected the contract of left-hander Jhonathan Díaz from Triple-A Tacoma, then optioned him to Tacoma. Ryan Divish of The Seattle Times relays on X that the lefty had an opt-out in his minor league deal, which is why he got added to the 40-man but not the active roster. They had an open 40-man spot and thus didn’t need to make a corresponding move.

Díaz, 27, signed a minor league deal with the M’s in January. He has since made nine appearances for Tacoma, eight starts, logging 51 innings with a 3.18 earned run average. He has struck out 26.2% of batters faced while giving out walks just 4.3% of the time. He has also kept 56.3% of balls in play on the ground. The fact that all that took place in the hitter-friendly Pacific Coast League makes it all the more impressive.

The lefty also has 35 1/3 innings of major league experience, which came with the Angels from 2021 to 2023. He had a 4.48 ERA in that time, though with his strikeout and walk rates matching at an unimpressive 14.4% level. He tossed 210 1/3 minor league innings over that same period of time with a 4.45 ERA, 24% strikeout rate and 9.2% walk rate.

The Mariners are clearly intrigued by the recent form Díaz has shown and didn’t want him to get away. He still has options and they had an open spot on the 40-man, they were able to simply add him there and keep him in Tacoma, preventing him from returning to the open market.

The M’s have a strong rotation right now composed of Luis Castillo, George Kirby, Logan Gilbert, Bryan Woo and Bryce Miller. On optional assignment, they have Emerson Hancock and Levi Stoudt as depth options, with Díaz now joining them as guys who could be recalled for a spot start or as an injury replacement.

Mariners Agree To Minor League Deals With Kirby Snead, Jhonathan Diaz

By | at

The Mariners have signed left-handers Jhonathan Diaz and Kirby Snead to minor league contracts, according to Matt Eddy of Baseball America. Both pitchers come from AL West rivals who had outrighted them at the end of last season.

Diaz had spent the past few years with the Angels. The 27-year-old got to the majors every season from 2021-23 but hasn’t tallied more than four appearances in any year. He pitched seven innings over four games last September, allowing 11 runs (eight earned) with seven walks and four strikeouts.

A swing option, Diaz started eight of 38 appearances with Triple-A Salt Lake. He logged 87 innings of 4.55 ERA ball for the Bees. Diaz kept the ball on the ground at a solid 48% clip but had middling strikeout (21.5%) and walk (11.1%) numbers. He’ll likely open next season with the M’s top affiliate in Tacoma as multi-inning depth.

Snead, 29, is a more traditional lefty specialist. Originally a Blue Jays draftee, he made a brief MLB debut with Toronto in 2021. The Jays included him as the fourth piece in the Matt Chapman deal with the A’s the following offseason. Snead pitched 44 2/3 innings for Oakland in 2022, allowing a 5.84 ERA.

A shoulder strain cost him the first three months of the 2023 season. Upon his return, he got into 15 MLB games. Snead allowed seven runs (six earned) across 11 2/3 frames. He fanned nine and issued six walks. The Florida product had a tough run in a very hitter-friendly Triple-A setting. Pitching for the A’s top affiliate in Las Vegas, he was tagged for a 7.59 ERA in 21 2/3 innings. He walked over 14% of opposing hitters.

Snead’s results the past two years haven’t been encouraging, but he managed a 1.58 ERA in 40 Triple-A innings back in 2021. He held left-handed batters to a .141/.222/.203 showing in 73 plate appearances that season. The M’s will see if a change in environment can help him recapture something closer to that ’21 form.
