Mariners Select Patrick Wisdom
The Mariners announced that they have selected the contract of infielder Patrick Wisdom. He will take the active roster spot of infielder/outfielder Rob Refsnyder, who has been placed on the paternity list. To open a 40-man spot for Wisdom, right-hander Blas Castaño has been designated for assignment.
Wisdom, 34, gets back to the majors for the first time since 2024. He spent a few years with the Cubs as an extreme offensive contributor. He would strike out a ton but also hit home runs. From 2021 to 2023, he hit at least 23 homers in each season but also struck out at least 34% of the time in each of those campaigns. His numbers declined in 2024 and he ended up in South Korea in 2025.
He had a strong showing overseas. He hit 35 home runs for the Kia Tigers, with a slightly improved strikeout rate of 29.2%. He parlayed that into a return to North America, signing a minor league deal with the Mariners. He has been crushing the ball in Triple-A so far, with nine home runs in just 15 games. His 22.6% strikeout rate is far better than his previous stints in the majors, though he has naturally been facing a lower level of competition. Even in the hitter-friendly context of the Pacific Coast League, his .264/.371/.774 line is far better than average.
During his time with the Cubs, Wisdom mostly played third base but he has only been used as a first baseman and designated hitter so far this year. The Mariners have Josh Naylor at first base. The DH spot has primarily been used for a platoon of the righty-swinging Refsnyder and the lefty Dominic Canzone. Wisdom swings from the right side and could perhaps replace Refsnyder in that platoon role. His splits aren’t huge but Wisdom has been better against lefties. He has a career .223/.298/.480 line and 112 wRC+ when facing southpaws, compared to a .201/.287/.448 line and 101 wRC+ against righties.
Stints on the paternity list generally only last a few days. A player is allowed to be away for one to three days. Every once in a while, special circumstances will keep a guy away from the club longer. In those instances, he has to be moved to the restricted list.
Assuming Refsnyder is back in the next days and everyone else is healthy, the Mariners could send Wisdom back to Triple-A without putting him on waivers. Despite his previous years in the majors, Wisdom has less than five years of service time and is still optionable. Players coming from overseas can sometimes have special language in their contracts about not being sent to the minors without their consent. Unless Wisdom has such a clause in his deal, it’s possible he could stick around as depth even after Refsnyder returns. Connor Joe is also on the club as a bench bat and isn’t playing much. He’s optionable as well, so that’s another possibility to consider.
Castaño, 27, has been on Seattle’s 40-man roster since November of 2024. Since then, he has only made one big league appearance. In May of last year, he pitched three innings of relief, allowing three earned runs via four hits and two walks while striking out one.
He mostly served as rotation depth in recent years but hasn’t been needed apart from that one outing. He tossed 126 2/3 Triple-A innings last year with a 5.19 earned run average. His 17.8% strikeout rate and 9.3% walk rate were subpar but he did get grounders on 46% of balls in play. So far this year, he’s been used out of the Triple-A bullpen. He has thrown 6 1/3 innings with a 1.42 ERA but has benefitted from a .125 batting average on balls in play, as his 19% strikeout rate is only a modest improvement from his work as a starter last year.
He’ll now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Mariners could explore trade talks for as long as five days. Castaño is still optionable, which could be appealing for clubs dealing with pitching injuries. If he clears waivers, he could stick with the Mariners as non-roster depth.

Mariners Select Casey Lawrence, Designate Blake Hunt
The Mariners have again selected Casey Lawrence onto the MLB roster. They optioned rookie righty Blas Castaño to Triple-A Tacoma while designating catcher Blake Hunt for assignment in corresponding moves.
This is already the fifth time this season that the Mariners have selected Lawrence’s contract. Each of the previous four was followed by a DFA within five days. One of those DFAs resulted in a waiver claim by Toronto, but Lawrence has otherwise cleared waivers. In each case, he either accepted a minor league assignment or re-signed with Seattle after briefly electing free agency. Lawrence also quickly returned to the M’s after being dropped by Toronto.
The 37-year-old is clearly content with the arrangement. He’s able to collect at least a day or two of MLB pay for each stint on the roster. Lawrence has provided multiple innings as a low-leverage relief option for skipper Dan Wilson. He has turned in a 4.08 ERA with seven strikeouts and one walk across 17 2/3 frames over six appearances. Castaño tossed three innings in mop-up work last night, so he’ll be unavailable for a few days. That led the Mariners to swap him out for Lawrence.
Seattle acquired Hunt from Baltimore in January. The righty-hitting catcher has fanned 29 times in 96 Triple-A plate appearances this season, hitting .231/.271/.407 in 25 games. Hunt has bounced between Seattle’s and Baltimore’s 40-man rosters but has yet to get into a major league game. He’s drawn praise for his power upside but has struggled to reach base against upper level pitching. Hunt is a .232/.284/.413 hitter in just shy of 500 career Triple-A plate appearances. He’ll be traded or, more likely, placed on waivers in the next few days.
Mariners Designate Jesse Hahn For Assignment
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 To Promote Blas Castano
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 Select Blas Castano
The Mariners announced they’ve added righty Blas Castano to their 40-man roster. As a player with parts of seven seasons in the minors, he would’ve otherwise qualified for minor league free agency.
Castano gets a 40-man spot for the first time in his career at age 26. The Dominican Republic native spent six seasons in the Yankee system before joining the Mariners on a minor league deal in August ’23. Seattle can keep him in the minors for the foreseeable future, as Castano has a full slate of option years. They’d need to run him through waivers to take him back off the 40-man roster.
Seattle was impressed enough with Castano’s 2024 season to not allow him to get away. The 5’10” righty split the year between the top two minor league levels. He threw 125 1/3 innings of 4.38 ERA ball, striking out 20% of opponents against an 8% walk rate. They’re not dominant numbers, though he fared better in Double-A before moving up to the hitter-friendly Pacific Coast League.
