Mariners Rumors

Jerry Dipoto Discusses Castillo, Lineup, Polanco

By | at

Mariners president of baseball operations Jerry Dipoto met with reporters this afternoon after the team finalized the one-year deal to retain Jorge Polanco. Seattle’s longtime front office leader addressed the team’s atypically quiet offseason while providing a couple injury updates.

Dipoto said the front office entered the winter believing they could be in for a slow offseason. “One of our points going into this offseason, and I know I made it sitting in the dugout in the final series, was that we didn’t anticipate a great deal of movement around the team,” he told the beat (including Ryan Divish of the Seattle Times). “As we are now about a week away from heading to Spring Training, I’d say that probably played out to be spot on, much to, I think, the dismay of a few. But we have a good team.”

Seattle has made two major league free agent signings. They brought Polanco back on a $7.75MM guarantee and added Donovan Solano as a part-time righty bat for $3.5MM. Reporting from both The Seattle Times and MLB.com throughout the offseason has suggested that ownership was only allowing the front office to allocate between $15MM-20MM to the MLB payroll. While the lack of free agent activity has certainly been a source of frustration for much of the fanbase, it’s not especially surprising.

The more interesting development has been the M’s willingness to sit out the trade market. They’ve made four trades this offseason, all of which have been depth acquisitions for players who were in DFA limbo: Austin Shenton, Miles Mastrobuoni, Blake Hunt and Will Klein. Those are akin to waiver claims. The Mariners essentially haven’t made a single notable move on the trade market, a stark contrast to Dipoto’s reputation as one of the game’s most prolific traders. The “Trader Jerry” nickname has been well earned in prior offseasons.

Most trade speculation concerned the possibility of the Mariners moving a starting pitcher to add a hitter. As Dipoto noted today, he did indeed downplay that notion before last season even ended. He famously called dealing from the rotation the M’s “Plan Z” for the offseason in the referenced media scrum. That didn’t stop other teams from inquiring on Seattle’s young rotation nucleus of George Kirby, Logan Gilbert, Bryce Miller and Bryan Woo, but there’s nothing to suggest the Mariners gave strong consideration to moving any of them.

The one starter who was available was Luis Castillo. The veteran righty is under contract for another three seasons and $68.25MM (plus a 2028 vesting option). Trading Castillo could have created spending room while netting the M’s immediate lineup help. It wasn’t going to be a straight salary dump, though, and Seattle hasn’t found an offer it finds compelling. The Seattle Times’ Adam Jude reported last week that Castillo was unlikely to move at this point.

Dipoto implied as much in today’s comments. He told Jude and other reporters that the front office received some proposals that warranted real consideration, but those obviously did not result in a deal. “Not shockingly, we had inquiries on all five of our starting pitchers and dozens of prospects along the way,” he added. “But obviously we opted not to go that route.” While he left open the possibility of making another move, he noted that the front office would be happy with the roster “if this is our team going into Spring Training or Opening Day” (via Divish and Jude).

The Mariners will go into Spring Training with arguably MLB’s best 1-5 in the rotation. Their depth behind that is lacking, though perhaps quick-moving prospect Logan Evans can soon be a factor. Seattle benefited from excellent rotation health last year. Woo was the only member of their front five who made fewer than 30 starts. That’ll be difficult to replicate, but when the rotation is at full strength, they’re giving the ball to an above-average starter every night.

As has long been the case, the question is whether they’ll score enough runs. Dipoto expressed confidence in the lineup, pointing to their success later in the season after the managerial and hitting coach changes. Seattle hitters had a .216/.301/.365 batting line through August 21. After dismissing Scott Servais and Jarret DeHart in favor of Dan Wilson and Edgar Martinez, respectively, they hit .255/.347/.417 in their final 34 games.

Attributing that entirely to the coaching changes is overly simplistic. They improved the lineup at the deadline with the Justin Turner and Randy Arozarena pickups and league-wide offense tends to peak later in the summer with warmer weather. Still, the change in voice probably played some part in the much improved finish. The Mariners play in the sport’s toughest home park for hitters. Only the White Sox had a lower team OPS in home games. Seattle ranked 13th in OPS on the road. Mike Petriello of MLB.com examined some reasons behind T-Mobile Park’s extreme pitcher-friendly environment last week in a column that’s well worth a full read.

Dipoto also addressed a few injury situations. He expressed confidence in Polanco’s health after the veteran infielder played through a left knee injury that eventually required a meniscus repair. The Mariners believe the move from his longtime second base position to third base will take less of a toll on him physically. Meanwhile, reliever Troy Taylor suffered a lat strain during his offseason workouts and will not be ready for the start of camp. It’s not clear if he’ll need to begin the regular season on the injured list. The righty turned in a 3.72 ERA while striking out nearly 31% of opposing hitters across 21 appearances as a rookie.

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 Designate Cade Marlowe For Assignment

By | at

The Mariners announced that outfielder Cade Marlowe has been designated for assignment. That is the corresponding move to open a roster spot for infielder Jorge Polanco, whose one-year deal to return to the club is now official.

Marlowe, 28 in June, was a 20th-round pick of the Mariners back in 2019. He continually posted good numbers as he was climbing the minor league ladder, so the Mariners gave him a roster spot in November of 2022 to keep him out of the Rule 5 draft. He has spent the past two years as a depth outfielder, getting only limited looks in the majors. To this point, he has received 109 big league plate appearances with a .240/.330/.406 line. His 11.9% walk rate in that time is strong but he’s also been punched out at a 31.2% rate.

His minor league numbers have tailed off in that time. He had a combined slash line of .281/.373/.523 over 2021 and 2022, which translated to a 129 wRC+. His 27% strikeout rate was on the high side but he offset it with an 11.5% walk rate and 49 home runs. But over 2023 and 2024, that line has been down to .246/.340/.419, translating to an 85 wRC+. His 11.9% walk rate was still good but the punchouts jumped even higher to 29.4%.

That diminished offense on the farm has seemingly nudged him off the edge of Seattle’s roster. They will now have at most a week of DFA limbo to figure out what’s next for him, whether that’s a trade or some fate on waivers. The waiver process takes 48 hours, so any trade talks would need to come together in the next five days.

He does still have one option remaining, so he could perhaps appeal to a club in search of some extra outfield depth. Though the offense has dipped, he has continued to be a threat on the basepaths. He has stolen between 24 and 43 bases in each of the past four minor league seasons. The strikeouts have been an issue even when at his best but he has some wheels, some pop, can take a walk and can be sent to the minors regularly for one more season, all of which adds up to an intriguing package overall.

Mariners Re-Sign Jorge Polanco

By | at

The Mariners are bringing back Jorge Polanco. They announced Monday that they’ve re-signed the veteran infielder to a one-year deal with a vesting/player option for the 2026 season. Polanco, an Octagon client, will reportedly be guaranteed $7.75MM. That comes in the form of a $7MM base salary in 2025 plus a $750K buyout on a mutual option. That mutual option can become a $6MM player option if Polanco reaches 450 plate appearances, and the option price would climb further, to $8MM, if he gets to 550 plate appearances. Polanco, who’ll move across the diamond and play third base for Seattle in 2025, can earn an additional $3.5MM worth of incentives. If he hits all of those incentives and picks up the player option, the contract would top out at $18.5MM over two seasons.

Polanco’s first season with the Mariners was a disappointment. Seattle acquired the switch-hitter from the Twins late last offseason. They expected him to provide a significant offensive boost in the infield. That didn’t pan out, as Polanco struggled through arguably the worst year of his career. He hit .213/.296/.355 with 16 home runs through 469 plate appearances. The batting average and on-base percentage were personal lows. The slugging percentage was only marginally above his career-worst .354 mark from the shortened 2020 season.

Before last season, Polanco had been one of the league’s more productive middle infielders. He combined for a .255/.333/.462 slash with a strong 10.1% walk rate in more than 1400 plate appearances over his final three seasons in Minnesota. Polanco had hit 33 homers back in 2021 and was an annual threat for 20 longballs and 30+ doubles. Polanco managed just 11 doubles during his first year in Seattle. He continued to draw walks at a solid 9.8% clip, but he struck out in more than 29% of his plate appearances.

Some of the offensive downturn is attributable to T-Mobile Park. Seattle plays in MLB’s most pitcher-friendly home stadium. Polanco had an especially difficult time at home. He hit .193/.284/.322 while striking out at a 31.9% clip in Seattle. His road production (.233/.308/.386 with a 26.7% strikeout rate) was better but still well below his previous standards.

Health may have been a bigger issue than the ballpark. Polanco underwent surgery to repair the patellar tendon in his left knee within weeks of the season’s conclusion. He had reportedly played through discomfort for a good portion of the season. Polanco is expected to be ready for the start of Spring Training. The Mariners are as familiar as any team with his health history. They evidently believe that last year’s struggles were something of an aberration.

While he’s entering his 10th full season, Polanco is only 31. His relative youth provides some optimism that last year was mostly a health-related anomaly. That said, the whiffs have been a multiyear concern. Polanco’s strikeout rate has climbed by multiple percentage points in five straight seasons. In 2020, he fanned in just 15.5% of his plate appearances. That jumped successively to a 25.7% clip in his final season with the Twins, which climbed nearly four points more with the Mariners.

Polanco’s previous contract included a $12MM team option that came with a $750K buyout. Seattle declined that relatively easily. Four months later, they bring him back at a slightly lesser salary. It’s probably not a coincidence that the performance bonuses theoretically allow him to max out next year’s guarantee at $11.25MM — the differential below the option price and the buyout.

They’re not quite running things back, as Polanco’s return comes with a position change. He has been a middle infielder throughout his career. Polanco played shortstop until moving to second base in 2021. He didn’t play anywhere other than second base last season. His major league third base experience consists of 20 starts and 180 innings. Polanco has never been a great defensive second baseman. His range could be less of an issue at third, though that’ll put some pressure on his arm. Polanco didn’t show great arm strength at second base, though that’s not a direct comparison to throwing across the diamond — which he did during his time as a shortstop.

Seattle feels more comfortable with their internal options at second base than they do at the hot corner. That bodes well for 25-year-old Ryan Bliss, who is likely to get first crack at the second base job. Bliss debuted late last season and hit .222/.290/.397 in 33 games. A former second-round pick by the Diamondbacks, he had a quality .269/.377/.456 showing over 433 plate appearances with Triple-A Tacoma last year.

The M’s will likely give Bliss the bulk of the playing time while working utilityman Dylan Moore through the position. Seattle’s lone additional MLB free agent signing, Donovan Solano, can also play some second base (though he’ll get more work as a platoon partner for Luke Raley at first). Seattle didn’t have anyone established at third base after non-tendering Josh Rojas.

Seattle wasn’t the only team interested in expanding Polanco’s versatility. He reportedly drew interest from the Astros as a possibility at either third base or in left field. Polanco has seemingly been Houston’s primary fallback if they don’t re-sign Alex Bregman. They no longer need a third baseman after landing Isaac Paredes in the Kyle Tucker deal, but they’re still hunting for a left fielder and would like to re-sign Bregman. That’d push Paredes to second and Jose Altuve to left field.

Seattle has reportedly had around $15-20MM in payroll space this winter. Solano and Polanco have accounted for just over $11MM, leaving a few million for a potential bench bat or middle relief pickup. RosterResource calculates their 2025 player payroll around $152MM.

Ken Rosenthal and Chandler Rome of The Athletic first reported that Polanco and the Mariners had an agreement. Rosenthal was first to report the $7.75MM guarantee and the move to third base. Ryan Divish of the Seattle Times reported that it was a one-year deal with a vesting/player option. Ari Alexander of KPRC 2 reported the $3.5MM in incentives. Jon Heyman of the New York Post provided the more detailed financial breakdown. Image courtesy of Imagn.

What Other Competitive Balance Round Draft Picks Could Be Traded This Winter?

By | at

The Competitive Balance Rounds are a pair of bonus rounds within the MLB draft, designed to give an extra pick to the game’s smaller-market teams.  Teams that fall within either the bottom 10 in revenues and market size are eligible, and since 2017, the league determined the eligible teams based on a formula involving market score, revenues, and winning percentage.  The first of the two Competitive Balance Rounds (CBR-A) comes right before the start of the second round, and CBR-B comes right after the second round.  For the 2025 draft, a total of 15 teams will gain an extra pick, and their order within their respective round is determined by their win totals in the 2024 season.

With that explanation out of the way, let’s get to the fun stuff — these picks can be traded.  Specifically, a CBR selection can traded exactly once, and to any team in the league.  Since these are the only MLB draft picks that are eligible to be dealt, it has become increasingly common to see teams move these extra selections as part of larger trade packages for established talent.

Three CBR picks in the 2024 draft changed hands due to trades, most prominently the Orioles’ inclusion of the 34th overall selection as part of the trade package sent to the Brewers for Corbin Burnes.  This offseason has already seen three CBR picks in the 2025 draft dealt, and this post will explore the possibility that some other teams with CBR selections might move these picks to fill a more immediate need.

To cover the broad reason why any of these teams might not make a trade, it’s simply that draft picks are a very valuable asset unto themselves.  Controllable young talent is particularly important for lower-revenue clubs that usually don’t splurge on expensive free agents or trade targets, which is part of the reasons why the Competitive Balance Rounds exist in the first place.  Clubs are naturally pretty reluctant to move these CBR picks unless the right opportunity presents itself on the trade market.

(First, some notes on the draft order.  The first 75 places in the 2025 draft have largely been established, since the remaining free agents who rejected qualifying offers all played for teams who were either luxury-tax payors in 2024, or aren’t revenue-sharing recipients.  That means that if Nick Pivetta signs elsewhere, the Red Sox will get their compensation pick after CBR-B.  If Pete Alonso and Alex Bregman sign elsewhere, the Mets’ and Astros’ compensation picks will fall after the fourth round.  Also, because the Mets, Yankees, and Dodgers all exceeded the second luxury-tax tier in 2024, their first-round picks were dropped by 10 spots in the draft order.  This means that these three big spenders are all technically selecting within CBR-A, but obviously these aren’t official CBR picks.  The only potential change would be if a team that signs Alonso, Bregman or Pivetta surrenders its second-round pick to do so.)

Onto the selections….

Brewers (33rd overall, CBR-A): Milwaukee is actually making consecutive picks in the draft, as they received a compensatory pick when Willy Adames rejected the team’s qualifying offer and signed with the Giants.  Owning the 32nd overall pick might make the Brew Crew slightly more opening to trading the 33rd overall pick, perhaps to add pitching or to the infield in the wake of Adames’ departure.  The Brewers could considering adding their CBR pick as a sweetener to try and move Rhys Hoskins’ contract, yet it’s less likely that the team moves a valuable draft selection just as part of a salary dump.

Tigers (34th overall, CBR-A): The Tigers are considered to be one of the top suitors remaining for Alex Bregman, and signing a qualified free agent would cost the Tigers their third-highest pick in the 2025 draft.  Losing the 63rd overall pick means the Tigers almost surely wouldn’t also deal their CBR pick.  If Bregman signed elsewhere, it’s more plausible that Detroit could consider trading its CBR pick for a big right-handed bat, but still probably on the unlikely side.

Mariners (35th overall, CBR-A): It was almost exactly a year ago that the M’s traded their CBR-B pick in the 2024 draft to the White Sox as part of the Gregory Santos deal.  Santos’ injury-plagued first season in Seattle could make the Mariners more hesitant to an even higher CBR selection, yet this tradable pick might an asset the M’s can use within an overall difficult offseason market for the team.  The Mariners are working with limited payroll space and most every team in baseball would prefer win-now help over prospects, seemingly leaving the M’s dealing with a lot of offers for their starting pitchers.  With Seattle so reluctant to deal from its excellent rotation, offering up the 35th overall pick in trade talks might help get things moving.

Twins (36th overall, CBR-A): Speaking of front offices without much financial flexibility, Minnesota has had a very quiet offseason, with most of the headlines focused on a potential sale of the franchise rather than any significant roster moves.  With reportedly around only $5MM or so in payroll space, the Twins might have to make some trades just to free up more money for more trade possibilities.  Moving the CBR-A pick could be added to the Twins’ list of possibilities, but the team has enough potential trade candidates on the active roster that moving a big league-ready player is probably their preference over dealing away a draft pick.

Rays (37th overall, CBR-A): It might not come as much surprise that Tampa is the team that has acquired the most CBR picks over the last seven seasons.  As you’ll see shortly, the Rays added to that total with the 42nd overall pick of the 2025 draft.  Like with the Brewers and the Adames compensatory selection, having an “extra” pick in a sense might make the Rays more open to dealing this pick here, but that hasn’t been Tampa Bay’s style.

Reds (now Dodgers, 41st overall, CBR-A): This pick was already moved, as Cincinnati traded its selection along with outfield prospect Mike Sirota to Los Angeles in exchange for Gavin Lux.

Athletics (now Rays, 42nd overall, CBR-A): Another swapped pick, as the A’s moved the 42nd overall pick to Tampa Bay as part of the Jeffrey Springs trade.  This move in particular highlights the speculative nature of this post, since going into the offseason, the Athletics seemingly wouldn’t have been on the radar as a team likely to trade its CBR pick.

Marlins (43th overall, CBR-A): There’s basically zero chance the Fish move a draft pick in the midst of their extensive rebuild.

Guardians (70th overall, CBR-B): The reigning AL Central champs have generally gone chalk with their CBR selections, not acquiring or trading any picks until this year.  Adding an experienced outfielder or middle infielder for the 70th pick might work on paper, as the Guards are another team with two CBR selections and not much spending capacity to address its roster needs.

Orioles (71st overall, CBR-B): The idea for this post came about after writing another piece yesterday about how the O’s might be well-suited to trade this pick.

Diamondbacks (now Guardians, 72nd overall, CBR-B): Arizona sent the 72nd pick and Slade Cecconi to Cleveland to bring Josh Naylor to the desert.

Royals (73rd overall, CBR-B): Kansas City traded its CBR-A selection just hours before the 2024 draft began, moving the 39th overall pick and third base prospect Cayden Wallace to the Nationals for Hunter Harvey.  While Harvey battled injuries and wasn’t much of a help in the Royals’ run to the ALDS, the fact that the team made such an aggressive midseason deal in pursuit of a playoff spot might hint that the front office is willing to make another bold swap involving this pick.  Outfield help remains the Royals’ biggest need at this point in the winter.

Cardinals (74th overall, CBR-B): Outgoing president of baseball operations John Mozeliak has spoken about wanting to leave a “clean slate” for new PBO Chaim Bloom.  Between that and the Cardinals’ stated goal of refocusing on player development, it seems unlikely St. Louis would look to move its CBR pick.

Pirates (75th overall, CBR-B): The Bucs have had a relatively quiet offseason, with the team’s typical lack of big spending.  In theory, trading a CBR pick might be a helpful way for the Pirates to add talent without breaking the budget, though Ben Cherington has yet to explore this tactic during his time as Pittsburgh’s general manager.

Rockies (76th overall, CBR-B): While the Rockies aren’t technically in an official rebuild, they’re not exactly building up after losing 204 games over the last two seasons.  Using this pick to add another young player to the farm system seems far more likely than the Rox trading the pick away.

Mariners Less Likely To Trade Luis Castillo; Twins Showed Interest

By | at

Luis Castillo’s name has swirled in trade rumors for much of the offseason, as since Castillo is far and away the priciest member of the Mariners’ rotation, Seattle has at least been more open to discussing Castillo than any of its other starting pitchers.  However, Adam Jude of the Seattle Times writes that a Castillo trade “is less likely now than it was early in the winter,” even if the Mariners will continue to explore other possibilities to build on what might be a mostly set roster.

Infield help was the Mariners’ clearest need heading into the winter, leading to natural speculation that the M’s would move Castillo or another starting pitcher for a clear-cut everyday player that could slide right as an everyday option at first, second, or third base.  This said, Seattle president of baseball operations Jerry Dipoto has long said that the M’s would trade from their rotation only as a last resort, so it might not be any surprise that the club is now moving away from Castillo after addressing its infield needs in free agency.

Jorge Polanco and Donovan Solano were both recently signed to one-year deals, adding a pair of experienced players to the infield mix for $11.25MM in guaranteed money.  These expenditures have absorbed much of the limited budget Dipoto had to work with, as Jude reiterates that the Mariners had roughly $15MM in available payroll space this winter.  Between this lack of spending ability and nearly league-wide demand for only MLB-caliber talent (rather than prospects) on the trade market, Dipoto’s hands may have been somewhat tied, and he opted to instead run it back with Seattle’s superb rotation rather than take the risk of diminishing the rotation for a hitting upgrade.

On paper, trading Castillo would’ve helped the Mariners both add a bat and cut some payroll, since the right-hander is owed $68.25MM in guaranteed money through the 2027 season.  (A vesting option for the 2028 season could add another $25MM in salary if Castillo remains healthy and tosses at least 180 innings in 2027.)  That said, Castillo’s salary was also no small consideration for other teams — in trade talks with the Red Sox, Boston was reportedly only willing to move Triston Casas for Castillo if Masataka Yoshida was also sent along with Casas as salary offset.

Several of the teams cited by MLBTR’s Nick Deeds in late December as potential Castillo trade fits have since acquired other pitchers, further narrowing Seattle’s list of options.  Opening Day is still eight weeks’ away, of course, so there’s plenty of time for the Mariners to pivot back to a Castillo deal if circumstances (i.e. injuries, a drop in asking prices) should change either for the M’s or a mystery team.

Perhaps as an example, the Twins hadn’t been considered as a potential landing spot for Castillo, but The Athletic’s Dan Hayes hears from a Twins source that reports that Minnesota did indeed check in with the Mariners about the veteran righty.  It doesn’t appear to be any more than a due diligence exploration, however, as Hayes suggests that Castillo’s contract is too pricey for the Twins’ liking.

Minnesota is also working within payroll restrictions, as Hayes writes that the Twins may have around $5MM in additional spending space for 2025.  Multiple reports suggest that the Twins would first have to trade some contracts off the books in order to make space for new acquisitions, which is why Christian Vazquez and Chris Paddack have been oft-mentioned trade candidates.

It was just over a year ago that the Twins and Mariners combined on a prominent trade that sent Polanco to Seattle in the first place, so the two teams have a recent working relationship.  Still, the two teams are somewhat in the same boat of trying to both fix some clear needs on their rosters while also spending as little as possible, leaving little common ground on the trade front.  Minnesota has been more recently linked to Dylan Cease’s market, and while prying Cease away from the Padres won’t be easy, his $13.75MM salary for just the 2025 season (Cease is a free agent next winter) is a better financial fit for the Twins’ books.

Mariners Sign Neftali Feliz To Minor League Deal

By | at

The Mariners’ announced 31 non-roster invitees to major league spring training today, most of whom were in-house prospects or previously reported veteran signees. One new name among the bunch is something of a blast from the past, as Seattle has invited former American League Rookie of the Year Neftali Feliz to big league camp.

Feliz, 37 in May, hasn’t pitched in the majors since 2021, when he pitched one inning for the Phillies and another three for the Dodgers. Prior to that, his last MLB work came back in 2017. He’s spent the 2022-24 seasons pitching for three different clubs in the Mexican League and fared quite nicely in an extremely hitter-friendly setting there, logging a 2.37 earned run average with a 26.3% strikeout rate and 9.8% walk rate in 121 2/3 innings. He’s tallied 54 saves along the way. Feliz is pitching for las Estrellas Orientales in the Dominican Winter League this offseason and has logged another 21 1/3 innings with a tiny 2.11 ERA. His 18.4% strikeout rate and 12.6% walk rate stand out less, however.

Back in 2010, Feliz saved 40 games for the Rangers and notched a 2.73 ERA in 69 1/3 innings, fanning 26.4% of opponents against a 6.7% walk rate en route to AL Rookie of the Year honors. He secured 20 first-place votes, handily topping runners-up Austin Jackson (Tigers) and Danny Valencia (Twins) in the top three of that year’s balloting.

Feliz had a generally successful but injury-marred tenure in seven seasons with the Rangers. He saved 93 games for Texas and posted a 2.69 ERA in 261 1/3 innings but had Tommy John surgery in Aug. 2012 and subsequently missed nearly all of the 2013 season. He was also limited to fewer than 50 frames in both 2014 and 2015. The Rangers cut him loose in July 2015, and he finished out the year with a shaky stint in the Tigers’ bullpen (7.62 ERA in 28 1/3 innings).

A 2016 deal with the Pirates brought about a rebound showing, but Feliz was roughed up again in 2017 while pitching for the Brewers and Royals. His 2017 season in Kansas City ended in August after he reported ongoing numbness in his right hand and was diagnosed with ulnar nerve palsy.

There’s no telling what to expect from Feliz now that he’s in his late 30s. At his peak, he averaged better than 96 mph on his heater and flashed a hefty 14.1% swinging-strike rate thanks to that power fastball and a sharp slider. He still sat 95 mph with his fastball in that very brief 2021 big league work. For the Mariners, there’s little harm in a non-guaranteed deal to see if Feliz’s recent work in Mexico can carry back over to an improbably late-30s return to the big leagues.

Mariners, Luis F. Castillo Agree To Minor League Deal

By | at

The Mariners have signed right-hander Luis F. Castillo to a minor league contract and invited him to big league camp this spring, Jon Heyman of the New York Post reports. The 29-year-old Castillo — obviously not to be confused with the eight-year MLB veteran of the same first and last name currently in Seattle’s rotation — pitched briefly with the Tigers in 2022 and has spent the past two seasons in Japan.

The younger Castillo has pitched 3 2/3 shutout frames in the majors, yielding only two hits and no walks with four strikeouts for Detroit in that ’22 cup of coffee. He carries a career 1.93 ERA in 18 2/3 Double-A frames and a 3.28 ERA in 60 1/3 Triple-A innings spread across two seasons. The Tigers outrighted him off their 40-man roster following the 2022 season, and he elected free agency before going on to sign with Nippon Professional Baseball’s Chiba Lotte Marines in Japan.

Castillo pitched well with the Marines, logging 49 innings with their big league squad and recording a 3.12 ERA with a sub-par 17% strikeout rate but a microscopic 1.5% walk rate. He faced 200 batters that season with the Marines and issued only three walks (plus another two hit batsmen).

Castillo parlayed that impressive showing into a bigger look with NPB’s Orix Buffaloes. As with the Marines, he pitched quite well. Castillo pitched 94 1/3 innings out of the Buffaloes’ rotation (15 starts) and notched a 2.96 ERA with an improved 19.6% strikeout rate. The absurd walk rate he demonstrated a year prior unsurprisingly proved impossible to sustain, but his 4.8% walk rate was excellent nevertheless.

Whether the newly signed Castillo will serve as rotation depth or compete for a spot in the bullpen isn’t clear. The Seattle rotation is stacked with the presence of the other Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller and Bryan Woo. Depth options like Emerson Hancock, Jhonathan Diaz and Blas Castano are all on the 40-man roster, while well-regarded prospect Logan Evans pitched quite well in Double-A last season and could be ready for a big league look this summer.

Poll: The Mariners’ Dilemma In Dealing From The Rotation

By | at

If there’s one standout trait about the Mariners headed in 2025, it’s their elite rotation; Seattle has the most impressive collection of young, cost-controlled starting pitching talent in the majors right now. Logan Gilbert, George Kirby, Bryce Miller, and Bryan Woo combined for more than 700 innings of 3.18 ERA baseball in 2024. Gilbert, who turns 28 in May, is the oldest of the group and the quartet has a combined 17 seasons of team control remaining.

That crop of talented young starters is the envy of the rest of the league, but if there’s a second standout trait about the 2025 Mariners it’s their questionable offense. Cal Raleigh is among the best offensive catchers in the game, but the lineup offers little certainty outside of him. Julio Rodriguez has superstar upside but didn’t show it for much of last year as he entered July hitting just .247/.297/.327. Randy Arozarena managed an excellent 11.7% walk rate down the stretch after being traded to the Mariners midseason, but hit just five home runs in 54 games and was worth just 1.9 fWAR overall last year between his time in Seattle and Tampa.

The trio of Raleigh, Rodriguez, and Arozarena all project to be above average hitters in 2025, but the rest of the lineup is well below average. Victor Robles enjoyed a career year after joining the Mariners midseason last year, but his elite performance in Seattle was carried by a .388 BABIP. Between that extreme good fortune with batted ball luck and his career .236/.311/.356 (81 wRC+) slash line prior to joining the Mariners, it’s hard to expect more than league average production from Robles in 2025. Dylan Moore and Luke Raley both posted solid numbers in 2025 but are platoon players who can’t be relied on in everyday roles, while J.P. Crawford, Mitch Haniger, and Mitch Garver were all well below average hitters in 2024.

The club’s only addition to the offense to this point has been Donovan Solano, who posted solid numbers in 2024 but figures to join Moore and Raley as another part-time player. A combination of Moore, Raley, and Solano seem likely to be capable of handling first and second base, but the club’s lineup still has a gaping hole at the hot corner after non-tendering Josh Rojas and declining Jorge Polanco’s club option. MLBTR explored the third base market as it pertains to the Mariners earlier this month, but none of the free agent options that fit their budget and lower-level trade candidates available are particularly inspiring.

The Mariners have been hesitant to trade from their excellent rotation, only reluctantly listening to offers on pricey veteran Luis Castillo and seemingly shutting down discussions regarding their young core of arms entirely. But shopping a cost-controlled, elite starting pitcher could open up new possibilities for the club to add impact talent that wouldn’t have been available otherwise. The Red Sox reportedly dangled an impact youngster in first baseman Triston Casas in exchange for either Miller or Woo earlier this winter, and it’s easy to imagine rotation-needy clubs offering similarly impactful talent in exchange for a young arm of that caliber.

Dangling Gilbert or Kirby would surely land the Mariners an even more enticing package in exchange given their solid track records of front-of-the-rotation work in the majors to this point. The Orioles, for example, have a deep group of positional talent but are in need of an impact starter. It’s not impossible to imagine Baltimore being willing to part with an established young talent like Jordan Westburg as the headliner in a package for someone like Gilbert, perhaps packaged with a less impactful cost-controlled arm like Dean Kremer to ease the blow to Seattle’s rotation.

Turning away from the Orioles, Mark Vientos of the Mets and Matt McLain of the Reds are among the other high-end, cost-controlled third basemen who the Mariners could theoretically seek as a headliner in a package for one of their top starters, though neither is quite as valuable as Westburg. Of course, such deals are easier to propose than actually execute. While a team like Cincinnati packaging McLain with one of their own rotation arms like Nick Lodolo in order to land an elite talent like Gilbert could make sense on paper, the injury history of both players could give the Mariners plenty of pause about giving up one of their most valuable assets for little in the way of certainty and the Reds may be equally hesitant to offer up two established players with All-Star upside in exchange for one.

That’s just one example, of course, but it’s equally difficult to imagine the Mariners lining up on the right trade package for a player as valuable as Gilbert or Kirby with the vast majority of rival clubs. High-end, cost-controlled starting pitching is the single most desirable asset in the sport, and while fans of rival teams have long dreamed of their GM working out a trade with Mariners president of baseball operations Jerry Dipoto to bring one of the Mariners’ young aces to town they’d surely start feeling queasy about the possibility upon seeing just how much their team would need to part with in order to land such a coveted talent.

If you were in the Mariners’ shoes, how would you approach the situation? Would you take the same course Dipoto has and simply refuse to seriously entertain offers for your elite group of young pitchers, looking to upgrade the team in other ways like by dealing Castillo? Would you listen to offers while holding firm on a high asking price? Or would you compromise on the value of one of your top assets in order to help bolster an offense in desperate need of impact?

Tyler Jay Elects Free Agency

By | at

The Mariners announced Tuesday that left-hander Tyler Jay, who was designated for assignment last week, went unclaimed on outright waivers. He’s elected free agency in lieu of an outright assignment to the minors. Seattle had claimed Jay off waivers from the Brewers earlier this month.

Selected with the No. 6 overall pick by the Twins back in 2015, Jay was viewed as a polished college arm who could move quickly as a reliever but also had a chance to start. He ranked as one of the Twins’ top prospects — and one of the top prospects in the sport — following that lofty selection, but repeated injury troubles derailed his once-promising trajectory. Jay dealt with continued shoulder and neck injuries throughout his time in the Twins’ system; Jay was at one point evaluated for symptoms believed to be related to thoracic outlet syndrome but wound up avoiding surgery.

Jay was out of affiliated ball entirely and pitching for the Joliet Slammers of the independent Frontier League when he caught the Mets’ attention and landed a minor league deal several years later, in 2023. The Mets gave him his big league debut in 2024 at 30 years old. He wound up splitting time between the Mets and Brewers, allowing four earned runs on nine hits and six walks with six punchouts in 7 2/3 innings of work.

While it was far from a dominant debut showing, Jay pitched quite well in the minors. In 56 2/3 innings at the Triple-A level this past season, the lefty notched a tidy 3.02 ERA with a 20.9% strikeout rate and very sharp 5.1% walk rate. He also kept the ball on the ground at a strong 47.3% clip and averaged just 0.64 homers per nine innings pitched.

Jay doesn’t throw especially hard, sitting just over 92 mph with his heater, but it was a nice season in the upper minors for a former top pick who seems to have put a good deal of the health troubles that plagued him early in his professional career behind him. He’ll now head to the market and look to latch on as a depth option for a club, likely one with a more pressing need for left-handed bullpen help (or at least fewer candidates to fill said need) than the Mariners have.
