Royals Acquire Matt Strahm

By Nick Deeds | December 19, 2025 at 10:47pm CDT

The Royals and Phillies announced a one-for-one reliever swap on Friday morning. Left-hander Matt Strahm heads to Kansas City with righty Jonathan Bowlan going to Philadelphia.

It’s a reunion for Strahm and the Royals, as Kansas City drafted the lefty in the 21st round of the 2012 draft. Strahm made his big league debut for the Royals in 2016 and spent parts of two seasons with the club before being shipped to the Padres in a six-player trade alongside Travis Wood and Esteury Ruiz in order to acquire Trevor Cahill, Brandon Maurer, and Ryan Buchter. Strahm had a career 3.81 ERA and 4.12 FIP in 56 2/3 innings at the time of the trade. He’ll now return to Kansas City nearly a decade later with more than 500 MLB innings and an All-Star appearance under his belt.

Much of Strahm’s tenure with the Padres was fraught with injuries and ineffectiveness, but a solid season with Boston back in 2022 convinced the Phillies to bring him into the fold. Since arriving in Philadelphia, the lefty has emerged as one of the league’s most effective relievers. He has a 2.71 ERA in 212 2/3 innings of work over the past three years with a 2.82 FIP and a 3.01 SIERA. That’s the eighth-most innings of any pitcher with ten starts or fewer over the past three seasons, and among qualified relievers his ERA ranks 10th, his FIP ranks 15th, and his SIERA ranks 21st.

That’s an elite combination of quality and quantity that virtually any bullpen would benefit from adding, and the Royals are no exception. Strahm figures to join closer Carlos Estevez and righty Lucas Erceg at the back of the Kansas City bullpen to create the best late-inning trio the Royals have had since the 2015 club’s “three-headed monster” of Greg Holland, Wade Davis, and Kelvin Herrera. With solid arms like Nick Mears, John Schreiber, and Daniel Lynch IV set to cover the middle innings, it’s not hard to imagine the Royals entering 2025 with one of the stronger top-to-bottom bullpens in the American League thanks to this trade. Mears just came over in the same trade that netted Isaac Collins for the Royals but sent lefty Angel Zerpa to the Brewers. Sending out Zerpa cut into Kansas City’s lefty relief group but they have quickly pivoted to Strahm to restock in that department.

The loss of Strahm will surely sting for the Phillies somewhat, but the club remains fairly well set up in terms of their late-inning mix. Jhoan Duran remains one of the league’s top closers, and the recently-acquired Brad Keller was one of the top setup men in the majors last year with the Cubs. From the left side, Jose Alvarado and Tanner Banks should form a quality duo, and Alvarado in particular has offered elite production in the past. Strahm’s name has long been in trade rumors this winter, and clearing his $7.5MM salary off the books could help the Phillies in the pursuit of a reunion with catcher J.T. Realmuto or help them to afford the addition of another outfielder, who could help contribute alongside Brandon Marsh, Adolis Garcia, and top prospect Justin Crawford.

Aside from the financial incentive to make the trade, the Phillies will also receive the services of Bowlan, a 29-year-old righty who made his big league debut in 2023 but just got his first extended look in the majors last year. Bowlan pitched quite well across 44 1/3 innings for Kansas City in 2025, posting a 3.86 ERA with a 3.97 FIP in that time. He struck out 25.6% of his opponents with a 9.4% walk rate and a solid 48.7% ground ball rate.

That ability to generate both strikeouts and grounders should make Bowlan an effective, low-cost addition to a Phillies pen that has plenty of solid options in the late innings but has plenty of spots still fairly unsettled. With less than one year of service time under his belt, Bowlan can be controlled through the end of the 2031 season, affording Philadelphia the opportunity to bring in an arm that could be part of their relief mix for years to come.

Robert Murray of FanSided first reported that Strahm was being traded to Kansas City. MLB.com’s Mark Feinsand had Bowlan going the other way.

Padres To Sign Sung-Mun Song

By Nick Deeds | December 19, 2025 at 9:55pm CDT

The Padres are in agreement with infielder Sung Mun Song on a contract, according to a report from Robert Murray of FanSided. According to Francys Romero of BeisbolFR, it’s a three-year deal that guarantees Song around $13MM.

Song, 29, has broken out in a big way over his last two seasons playing for the KBO’s Kiwoom Heroes. After typically being a slightly below average hitter by that league’s standards in the early years of his career, Song exploded with a .340/.408/.518 (143 wRC+) slash line across 602 plate appearances during the 2024 season. He flashed 20/20 potential at the plate and walked at a career-high 10.6% clip while primarily playing third base for the Heroes. He followed up on that season with an even better year in 2025, as he slashed .315/.387/.530 (151 wRC+) with 26 homers, 25 steals, and 37 doubles in 646 trips to the plate.

Those dominant back-to-back campaigns in the KBO league were enough to convince Song to try his hand in the majors, and the Heroes made Song’s goal a reality when they posted him for MLB clubs last month. That opened a 30-day window (set to close on the 21st of December) for Song to negotiate with MLB clubs. Song has typically been viewed by scouts as a step below MLB Gold Glove winner Ha-Seong Kim, the best South Korean player to make the jump to the majors in recent years, and there’s been some debate about whether he’s more of a utility player or a proper starter at the big league level.

Song’s reported price tag is certainly affordable enough for the Padres to stomach in the event he’s more of a bench piece than a regular. A multi-year pact that pays Song less than $5MM annually figures to be quite affordable for San Diego; Jose Iglesias earned $3MM last year after being added to San Diego’s roster on a minor league deal to fill out the club’s bench mix. Song figures to fill a similar role this year to the one Iglesias held last season, chipping in around the infield and serving as a pinch-hitter.

While Song has primarily played third base throughout his career in the KBO league, that position is manned by Manny Machado in San Diego. Perhaps the Padres will look to get Machado occasional DH reps headed into his age-33 campaign, but aside from those occasional fill-in days Song figures to spend most of his time at first and second base, both of which are positions he logged significant time at in South Korea. Jake Cronenworth is currently slated to serve as San Diego’s second baseman next year, though his name has popped up in trade talks this winter. First base meanwhile, is unsettled after the departure of Luis Arraez. Gavin Sheets has some experience at the position but may be better suited for DH duties. As a result, first base could be Song’s best shot at regular reps, though it’s possible a trade of Cronenworth or the addition of a more traditional first base option like Paul Goldschmidt or Rhys Hoskins changes things.

The signing of Song comes just one day after the club agreed to reunite with right-hander Michael King on a three-year, opt-out laden contract. According to RosterResource, the Padres project for a payroll just under $217MM in 2026, with a payroll of nearly $258MM for luxury tax purposes. That’s before the addition of Song to the payroll, which at the currently reported numbers would push the team’s payroll up to around $221MM and around $262MM for luxury tax purposes. That would put them just barely below the second, $264MM luxury tax threshold for 2026.

If the Padres don’t want to go over that line, they would need to subtract salary from the roster to make virtually any more additions to the roster. That’s far from impossible, as rumors have percolated around not only Cronenworth but also players like right-hander Nick Pivetta and Ramon Laureano. A trade of Pivetta would save $20.5MM in 2026 and $13.75MM for luxury tax purposes. Cronenworth being dealt would save roughly $12.3MM in 2026 and $11.5MM for luxury tax purposes. Laureano wouldn’t save nearly as much money, as he’s due just $6.5MM next season on the final year of his contract.

Of course, it’s also possible the Padres simply stand pat from here, though doing so without adding another bat to the first base/DH mix would certainly be risky. Perhaps an addition on the trade market that comes with a lower financial cost could make some sense if San Diego neither wants to exceed the second luxury tax threshold nor trade salary to make room in the budget. Players like Triston Casas of the Red Sox and Mark Vientos of the Mets could potentially be available this winter and remain under affordable team control.

Diamondbacks Sign Merrill Kelly

By Nick Deeds | December 19, 2025 at 2:45pm CDT

The Diamondbacks officially announced a reunion with Merrill Kelly on a two-year contract with a 2028 vesting option. The Apex Baseball client is reportedly guaranteed $40MM. He receives a $2MM signing bonus and will make successive $17MM and $21MM salaries. If Kelly reaches 170 innings in 2027, he’ll lock in a $12MM salary for the 2028 season. If he reaches 185 innings in ’27, that ’28 guarantee will jump to $14MM. The D-Backs cleared a roster spot earlier by flipping Kyle Backhus to the Phillies.

The 37-year-old Kelly returns to the team with which he has spent nearly his entire major league career. Though initially drafted by the Rays in the eighth-round of the 2010 draft, Kelly made his big league debut with the Diamondbacks back in 2019 after a four-season stay in Korea as a member of the KBO’s SK Wyverns (now known as the SSG Landers). After a pedestrian rookie campaign in the majors where he pitched to a league-average ERA in 32 starts, Kelly managed to fashion a role for himself as one of the better mid-rotation arms in the majors.

Since the start of the 2022 campaign, Kelly has pitched to a 3.47 ERA in 108 starts. He’s struck out 23.1% of his opponents while walking 7.7% in that time, leaving him with a 3.81 FIP. Although a 4.03 SIERA and other so-so peripherals cast him as a step down from your prototypical front-end starter, the veteran has managed to remain a durable and productive rotation piece. Kelly particularly endeared himself to Arizona fans when he delivered a brilliant 2.25 ERA over 24 postseason innings during the club’s run to the World Series in 2023.

Amid a disappointing 2025 season where the Diamondbacks were ravaged by injuries to everyone from star closers Justin Martinez and A.J. Puk to newly-signed ace Corbin Burnes, the team engaged in a sell-off at trade deadline and shipped Kelly to the Rangers in exchange for a trio of pitching prospects. Kelly put up fairly pedestrian numbers across ten starts with the Rangers: a 4.23 ERA and near-matching 4.18 FIP across 55 1/3 innings of work.

Even while the veteran was in Texas, an offseason reunion with the Diamondbacks was already being speculated upon. Kelly spoke fondly of Arizona and expressed an openness to re-signing when asked about the possibility while the Rangers were visiting Chase Field in the season’s final few weeks. “Definite” interest in a reunion with Kelly was reported on Arizona’s side shortly before last week’s Winter Meetings, and now the sides have come together on a deal.

Turning to the deal itself, Kelly’s $40MM guarantee clocks in just ahead of the two years and $36MM MLBTR predicted for the right-hander when ranking him as the #25 free agent in this offseason’s Top 50 MLB Free Agents list. The Snakes were aggressive both in their offer and the timing of the deal; while the free agent market for position players and especially relievers has kicked into gear already, Kelly is just the third starting pitcher from MLBTR’s Top 50 to sign a contract this offseason. He joins Dylan Cease and Cody Ponce, both of whom received guarantees that slightly eclipsed MLBTR’s predictions.

Now that he’s set to return to Arizona, Kelly stands as the favorite to start for the Diamondbacks on Opening Day this year. He’ll join a rotation that already added Michael Soroka and will reunite with former teammates Eduardo Rodriguez, Brandon Pfaadt, and Ryne Nelson. Burnes could be a factor later in the season but is not expected to pitch until sometime in the second half after undergoing Tommy John surgery in June. While the team’s rotation certainly looks much more complete with Kelly back in the fold, bringing the right-hander back shouldn’t stop the team from pursuing other rotation additions after the club’s pitching staff finished 19th in the majors with a 4.29 ERA last year.

Of course, adding beyond this could prove to be easier said than done. The Diamondbacks are projected for a payroll just north of $171MM in 2026, according to RosterResource. That rises to north of $205MM for luxury tax purposes. GM Mike Hazen has suggested that, while Arizona’s payroll would likely be moving downward from its 2025 level, that would still leave the team with room to spend. The club spent $188MM on its payroll last season, however, meaning they currently sit less than $17MM from that mark.

Perhaps that leaves enough wiggle room to reunite with Paul Goldschmidt on an affordable one-year deal, a move the Diamondbacks have been said to be contemplating, but Kelly will surely go down as the team’s biggest expenditure unless an increase in payroll is approved or the team makes a trade that clears salary. To that latter point, the hot stove has been burning with Ketel Marte trade buzz in recent weeks. Moving Marte would certainly clear payroll off the books (and simultaneously add some young rotation options as part of the return), though Hazen has consistently downplayed the likelihood of a deal surrounding Marte actually coming together.

Ken Rosenthal of The Athletic first reported the Diamondbacks and Kelly were finalizing a two-year, $40MM deal. Nick Piecoro of The Arizona Republic reported the option specifics. David Brandt of The Associated Press had the salary structure.

Poll: Who Will Sign Kyle Tucker?

By Nick Deeds | December 18, 2025 at 12:29pm CDT

As the New Year approaches, star outfielder Kyle Tucker is reaching rarely-charted territory as this winter’s top free agent. Juan Soto signed just before the Winter Meetings last year, while two years ago Shohei Ohtani signed with the Dodgers shortly thereafter. Aaron Judge signed with the Yankees on the final day of the Winter Meetings three years ago, and Carlos Correa agreed to $300MM deals with both the Giants and Mets in December 2021, though both of those deals ultimately ended up falling through.

If Tucker is going to follow in the trend of top free agents finding a new home in December, he’s running out of time to do so. It’s been an unusually quiet free agency for the offseason’s biggest star. While any lineup would be significantly better off for adding someone who’s hit .277/.365/.514 over the past five seasons, few teams have actually been connected to Tucker directly. Some of that could be due to a lack of interest from the teams that know Tucker best. While Ohtani, Judge, and Soto were all pursued by the teams they were departing in free agency, that’s not so for Tucker.

The incumbent Cubs have made it extremely clear this offseason that they don’t have much intention of reuniting with Tucker, instead preferring to peruse the high-end rotation market and go with youngsters like Moises Ballesteros and Owen Caissie to replace Tucker’s big lefty bat in the lineup. Tucker’s previous team, the Astros, have never spent anywhere close to what it would take to bring Tucker back to Houston on a free agent deal and seem unlikely to start now. While both clubs’ lack of interest in Tucker seems to be more about a hesitance regarding long-term deals than anything regarding Tucker specifically, it still takes two logical fits out of his marketplace.

That doesn’t mean there’s been zero interest in Tucker, of course. The Blue Jays reportedly invited Tucker to their Spring Training facility earlier this month and have been by far the team most frequently connected to the outfielder. With that being said, Toronto is also known to have interest in retaining star infielder Bo Bichette. After signing Dylan Cease last month, the club may not have the appetite to add two more megadeals to the books. The Orioles are in a similar boat, having been expressly connected to Tucker on multiple occasions but now appear to be more or less out of that market after bringing in Taylor Ward and Pete Alonso.

Other more speculative suitors have few clear obstacles to signing Tucker but come with their own caveats. The Dodgers have space in their outfield and were connected to Tucker early in the winter but have expressed concerns about the aging nature of their roster, have a stable of intriguing outfield prospects, and seem to prefer to go smaller this winter than they have in recent years. That doesn’t mean they won’t sign Tucker, but it seems as though they might only have interest in him on a shorter-term deal (or perhaps following a trade of Teoscar Hernandez, though that appears unlikely).

The New York teams appear to be in a similar boat to Los Angeles. The Yankees pursued Tucker on the trade market last winter and have space in their outfield for another big bat, but appear to be focused on Cody Bellinger at this point. Even if they miss on Bellinger, GM Brian Cashman has expressed concerns over their lineup being too left-handed. The Mets, meanwhile, cleared a spot in their outfield mix when they dealt Brandon Nimmo to the Rangers. With owner Steve Cohen’s willingness to spend, a big contract for a star can never be entirely ruled out. With that said, president of baseball operations David Stearns has mostly shied away from longer term deals. While exceptions were made for pursuits of Soto and Yoshinobu Yamamoto, both of those stars were three years younger than the soon-to-be 29-year-old Tucker.

It’s always possible a surprising team steps up and makes a big offer, but there aren’t many clear candidates for that sort of bid looking around the league. The Giants are known to be interested in adding to their outfield, but they just landed a big contract over the summer when they traded for Rafael Devers and might not want to add Tucker to books that already include Devers, Willy Adames, Matt Chapman, and Jung Hoo Lee long-term. The Phillies seemed like a fit at one point, but their reunion with Kyle Schwarber and their signing of Adolis Garcia make that difficult to see now. The Tigers once spent at a high level with big deals for players like Miguel Cabrera, but haven’t done so under Chris Ilitch even while competitive. The Angels have made big splashes in free agency for position players before but might not want to add another big contract as they negotiate a buyout for the player they brought in on their last megadeal.

Where do MLBTR readers think Tucker will ultimately land? Will the Blue Jays pony up for him, even if it means spurning Bichette? Will he be the latest star to fall into Andrew Friedman’s lap in free agency? Will a New York team step up? Or could a surprise contender swoop in and sign him? Have your say in the poll below:

The Opener: Bichette, Relief Market, Noel

By Nick Deeds | December 18, 2025 at 9:01am CDT

Here are three things we’ll be keeping an eye on around the baseball world today:

1. How would Bichette’s market change as a second baseman?

Reporting yesterday indicated that star infielder Bo Bichette is open to moving off shortstop and playing second base for interested clubs. That’s not necessarily a surprise, as free agents such as Willy Adames and Alex Bregman have suggested a similar level of positional flexibility in recent free agent classes, and Bichette of course played second base during the World Series after returning from a knee injury. Bichette’s defensive metrics at shortstop have ranged from slightly below average to well below average throughout his career, and a move to the keystone could make him a stronger defender overall.

The market for second base help has been rather hot this winter. Brendan Donovan and Ketel Marte have been two of the most talked-about names on the trade market, and other second basemen like Brandon Lowe and Jazz Chisholm Jr. have also drawn interest. Given the questions about Bichette’s glove at shortstop and the lack of big-spending teams looking for a new starting shortstop, voicing a willingness to play second base should open up Bichette’s market a bit more.

2. High-leverage relievers continue to dwindle:

The relief market has been bustling all winter, and yesterday was no exception. Right-handers Brad Keller and Luke Weaver signed identical two-year, $22MM contracts with NL East clubs as Weaver joined the Mets and Keller joined the Phillies. That leaves precious few high-end relievers available for teams like the Yankees, Cubs, and Marlins to pursue. Pete Fairbanks and Seranthony Dominguez are among the best options remaining on the market at this point, with hurlers like Shawn Armstrong and Pierce Johnson sitting a tier below those two.

3. Big Christmas in DFA limbo:

The Guardians parted ways with Jhonkensy Noel yesterday, designating the outfielder for assignment to make room on the 40-man roster for southpaw Justin Bruihl. It’s not necessarily a shock to see Noel lose his roster spot given his brutal 2025 season; the 24-year-old slashed just .162/.183/.297 across 69 games with Cleveland last year. With that said, fans surely remember Noel’s far stronger 2024 campaign where he slugged 13 homers in 67 games with a wRC+ of 118 before going on to hit a game-tying home run against the Yankees in the ALDS. Will any clubs look past Noel’s strikeouts and approach and bet on his immense raw power with a small trade or waiver claim?

Athletics Sign Mark Leiter Jr.

By Nick Deeds | December 17, 2025 at 4:30pm CDT

December 17th: The A’s have officially announced their signing of Leiter.

December 11th: The Athletics have reportedly reached an agreement with right-hander Mark Leiter Jr. on a one-year, $2.85MM contract. The signing is still pending a physical. Leiter is a client of VC Sports Group.

Leiter, 35 in March, made his big league debut back in 2017 but didn’t fully establish himself at the big league level until joining the Cubs in 2022. He served as a swing man and long reliever for Chicago that year, with a 3.99 in 67 2/3 innings of work in that role, but moved to a short relief role full-time in 2023. In 100 2/3 innings of work for the Cubs over the next two seasons, Leiter pitched to a 3.75 ERA with a 3.12 FIP while striking out 30.9% of his opponents and walking 8.8%.

Those exciting peripherals were enough to convince the Yankees to swing a trade for the right-hander at the 2024 trade deadline, but he struggled in New York even as his peripheral numbers remained strong. In 70 innings of work for the Yankees over parts of two seasons with the club, Leiter posted a 4.89 ERA despite a 4.07 FIP. In 2025, Leiter struck out 24.7% against a 7.8% walk rate while generating grounders on 45.5% of his batted balls allowed. Unfortunately for the righty, the results weren’t there enough for the Yankees to tender him a contract last month, and he wound up reaching free agency a year earlier than anticipated.

Headed into 2026, the A’s can expect Leiter to be a solid middle relief arm at least. His 4.15 ERA over the past four seasons is exactly league average (100) by ERA+, and the right-hander’s impressive splitter actually makes him particularly effective against left-handed batters. In 104 2/3 innings of work against lefties the last three years, Leiter has posted a 2.49 ERA and 2.57 FIP with a 32.1% strikeout rate. With league average results overall and elite numbers against lefties, Leiter has a much higher floor than a typical non-tendered middle relief arm, which is surely why he was able to command a solid guarantee even coming off a tough year in New York.

Leiter hasn’t managed to play up to his peripherals throughout his career, but if he can do so he could wind up a valuable setup man for the A’s this year. The righty’s 3.13 SIERA over the past three seasons ranks 13th among relievers with at least 150 innings of work since the start of the 2023 season, and that puts him on a similar level to well-regarded late-inning arms like Luke Weaver. Leiter’s .359 BABIP and 66.5% strand rate over the past two years indicate extremely poor fortune when it comes to batted balls and sequencing; if those numbers experience enough positive regression to get within spitting distance of league average, Leiter’s a good bet to be impactful at the back of the A’s bullpen next year.

It’s been a quiet offseason for the A’s so far, though there’s certain reasons for optimism regarding the club’s future. Nick Kurtz emerged as a potential superstar this year, and he’s backed by a core of exciting positional talent like Brent Rooker, Shea Langeliers, Jacob Wilson, and Lawrence Butler. The club’s pitching staff needs plenty of work if the team is going to contend in 2026, but adding Leiter to a bullpen that already houses respectable arms like Hogan Harris and Michael Kelly should be a small step towards accomplishing that goal. Jeffrey Springs and Luis Severino remain in the fold as solid back-of-the-rotation veterans, though it remains to be seen how much A’s ownership is willing to spend in order to augment that group. Whether the A’s are facing significant budget constraints or not, however, bringing Leiter into the fold as a reliever with possible late-inning upside on a relative bargain can only be a good thing for the club.

Robbie Hyde of Foul Territory first reported the agreement. Janie McCauley of The Associated Press reported the $2.85MM guarantee, after ESPN’s Jesse Rogers first noted it would close to $3MM.

Poll: Should The Mets Trade Mark Vientos?

By Nick Deeds | December 17, 2025 at 12:51pm CDT

After losing Pete Alonso to the Orioles in free agency and trading Brandon Nimmo to the Rangers, the Mets will need to reconfigure their lineup in a big way this winter. They’ve already added some of the pieces with which they’ll try to do that, bringing in Marcus Semien as the return for Nimmo and following that up by signing Jorge Polanco, but there’s clearly more work to do. It’s with that backdrop that reporting yesterday indicated the Mets could look to trade infielder Mark Vientos this winter, perhaps while eyeing the addition of a big bat to the lineup.

Trading Vientos certainly has some merit. The 26-year-old was a merely league average hitter by the numbers this year, with a 97 wRC+ thanks to his 40 extra-base hits (including 17 homers) propping up a paltry .289 on-base percentage. That sort of production won’t cut it for a poor defensive third baseman who figures to get the majority of his playing time at first base or DH next year, but his youth and power potential could still be enough to catch the eye of some teams in need of right-handed pop in their lineup, with the Mets perhaps getting some pitching back in return.

With that being said, trading Vientos wouldn’t come without risk. Still in his mid-20s, Vientos has already demonstrated the ability to potentially be an All-Star caliber bat. In 2024, he slashed .266/.322/.516 (132 wRC+) with 27 homers in 111 games. It was a strong enough performance to play as a regular at first base or overlook his defensive deficiencies at the hot corner. If the youngster can rediscover that form, he would offer the Mets a major boost. After all, the Mets themselves need additional righty pop in the lineup after losing Alonso. Letting their veteran slugger walk was already tough for fans to stomach and it would surely get even worse if Alonso’s heir apparent was traded away and broke out somewhere else.

How likely is a return to form for Vientos? The underlying metrics are mixed. Vientos didn’t live up to his expected numbers last year, which could be a sign that some positive regression is on the way. He actually lowered his strikeout rate substantially, dropping from 29.7% in 2024 to just 24.8% this year. Those are good signs and his .277 BABIP this season seems likely to improve going forward. With all of that being said, however, there are certainly some red flags. While his BABIP is likely to improve from last year, it’s unlikely to reach the level of his .324 mark from 2024. While his strikeout rate dropped by nearly five points, his once-elite barrel rate dropped by nearly three. In all likelihood, his true talent level lies somewhere between his weak 2025 and his impressive 2024.

The question then becomes about which side of the spectrum Vientos is more likely to fall on. If he figures to offer a bat with a wRC+ of 120 or greater on a consistent basis going forward, that would be hard to part with for a team in need of right-handed power like the Mets. With that said, if Vientos is more likely to be just a touch better than league average this year, it would be fair to wonder if the Mets would be better off focusing on adding a more impactful player like Kazuma Okamoto and Munetaka Murakami to the first base/DH mix.

Perhaps going with a free agent hitter in Vientos’s place and turning Vientos into a trade chip for pitching would be a smart call. Despite his uneven performance, other clubs would surely be interested in him, especially since he’s cheap. He has not yet qualified for arbitration and can be controlled for four full seasons before he’s slated for free agency.

With that said, it’s also worth considering how a more expensive addition like Okamoto or Murakami could impact the Mets’ ability to pursue an impactful outfielder. Cody Bellinger has been tied to the Mets frequently this winter, and while the rumors connecting the club to Kyle Tucker haven’t been nearly as ubiquitous, the possibility of a deal there is worth considering given the club’s need for outfield help and the small numbers of teams that could realistically meet his rumored asking price. If sticking with Vientos gave the Mets a better shot to land a big outfield bat, then perhaps the club would be better off keeping Vientos in the fold and trying to deal other young players and prospects for pitching help.

How do MLBTR readers think the Mets should proceed with Vientos? Should they keep him, risking an underwhelming 2026 season in order to keep their focus on improving the outfield in free agency? Or should they trade him and risk a breakout elsewhere in order to add more certainty to the lineup? Have your say in the poll below:

The Opener: Giants, Lefty Relievers, Posting Windows

By Nick Deeds | December 17, 2025 at 8:52am CDT

Here are three things we’ll be keeping an eye on around the baseball world today:

1. Giants 40-man roster moves incoming:

The Giants signed right-handers Adrian Houser and Jason Foley to major league deals yesterday, and in doing so created in a logjam on their 40-man roster. San Francisco’s roster was already at capacity before those signings, so they’ll need to make a pair of corresponding moves in order to finalize those additions. Those transactions could be simply designating two other players for assignment, but it’s also possible that the Giants could look to work out a trade of some kind that clears 40-man roster space.

2. Market for lefties heating up:

While the bullpen market has been buzzing virtually the entire offseason, the market for specifically left-handed relief pitching had been a bit quieter until recently. As of early last week, Gregory Soto was most notable lefty to sign, but that dam has broken. Hoby Milner and Tyler Alexander signed late last week, and things picked up further yesterday with a trio of agreements: Caleb Thielbar returned to the Cubs after a strong rebound season, Drew Pomeranz signed with the Angels, and the Reds landed Caleb Ferguson. With that group off the board, the most notable lefties still on the market include Sean Newcomb, Taylor Rogers, Justin Wilson and Danny Coulombe.

3. Posting windows for Song, Murakami nearing their end:

When international players are posted for MLB teams, they’re given a limited window during which to sign. That window lasts 30 days for players coming over from the KBO, while NPB players have 45 days. Two such players are having their windows draw to a close in the next few days: KBO infielder Sung Mun Song, who will need to sign by December 21 at 4pm CT, and NPB slugger Munetaka Murakami, who will need to sign by December 22 at 4pm CT.

Murakami is by far the more well-known player, heralded for his youth and prodigious power despite concerns about his contact ability. He should land a healthy multi-year deal in free agency, though his camp has kept things very quiet to this point. Song hasn’t garnered as much fanfare but is coming off a pair of terrific seasons, wherein he combined to his .327/.397/.524 with a 10.5% walk rate and just a 14.3% strikeout rate.

Mutual Interest In Reunion Between Luke Weaver, Yankees

By Nick Deeds | December 16, 2025 at 9:37am CDT

The Yankees have expressed “genuine interest” in bringing right-hander Luke Weaver back into the fold, according to a report from The Athletic’s Chris Kirschner. Weaver has likewise expressed interest in a reunion, though Kirschner notes that the righty is weighing his options and is seeking a multi-year deal this winter. The report adds that “about 10 teams” have at least checked in on Weaver this offseason.

Weaver, 32, was a first-round pick by the Cardinals back in 2014 and struggled as a back-of-the-rotation starter in the majors for years before moving to the bullpen with the Yankees in 2024. He’s been excellent in that role over the past two years, with a 3.21 ERA and 3.58 FIP across 148 2/3 innings of work. He’s picked up 12 saves with the Yankees in that time, but struggled late in the 2025 season with a 5.35 ERA from the start of July onwards, including a 9.64 ERA in 12 September appearances. Worrying as that late-season meltdown might be, however, a 2.96 xERA and 3.44 SIERA both indicate that he’s still a quality reliever and remains among the best options available on the market.

That’s especially true after the run on high-end relievers that’s taken place in the early weeks of free agency. Edwin Diaz, Devin Williams, Tyler Rogers, Raisel Iglesias, Kyle Finnegan, and Emilio Pagan are just some of the names on an expansive list of late-innings arms who have already landed somewhere, while the Yankees have yet to add to their bullpen at all this winter. The summer’s additions of David Bednar and Camilo Doval help to reduce pressure to land a high-end relief arm, but the loss of Williams and the potential loss of Weaver still leave a hole towards the back of the Yankees’ bullpen. Weaver is joined by former Rays closer Pete Fairbanks and 2025 standout Brad Keller as the top remaining relief arms in free agency, and it would surely behoove New York to add at least one of those players.

Of course, that doesn’t mean a deal will necessarily come together. The Yankees, as Kirschner notes, have recently been hesitant to give out multi-year deals to relievers in free agency. With Weaver seeking a multi-year contract and garnering interest from as much as a third of the league, it’s entirely possible that he’ll find the offer he’s looking for elsewhere if the Yankees aren’t willing to meet that price tag. The Cubs, Marlins, and Mets are among the other teams known to be looking for late-inning relievers this winter. If the Yankees continue to be hesitant about adding a multi-year reliever, they could move down a tier in free agency and target arms like Pierce Johnson, Chris Martin, or perhaps even old friend David Robertson. The trade market could provide another alternative, where Cardinals lefty JoJo Romero is among those known to be available.

The Opener: Griffin, Rangers, Roster Moves

By Nick Deeds | December 16, 2025 at 8:21am CDT

Here are three things we’ll be keeping an eye on around the baseball world throughout the day today:

1. Griffin nearing deal?

Yesterday, it was reported that left-hander Foster Griffin has received major league offers, including at least one multi-year offer. A former first-round pick by the Royals, the southpaw has just eight innings of MLB experience but enjoyed a brilliant campaign in Japan this year, with a 1.62 ERA and a 25.1% strikeout rate in 78 innings of work for Nippon Professional Baseball’s Yomiuri Giants. MLBTR’s Steve Adams reported yesterday that Griffin has spoken to eight different teams with varying interest levels in his services, while MLBNetwork’s Jon Morosi added that a deal could come together soon for Griffin. Which team will land the intriguing lefty?

2. Rangers press conference today:

The Rangers made official a pair of previously reported free agent signings yesterday when they announced the additions of catcher Danny Jansen and left-hander Tyler Alexander. Jansen replaces Jonah Heim in Texas’s catching tandem alongside Kyle Higashioka, while Alexander adds another lefty to the club’s bullpen to complement setup man Robert Garcia. At 11am local time today, president of baseball operations Chris Young and GM Ross Fenstermaker will be holding a press conference over Zoom to discuss the club’s latest signings with reporters. Amid an offseason where the Rangers are known to be limited in their ability to spend, today’s press conference could offer some indication towards the club’s plans for the remainder of the offseason and how much flexibility remains in the team’s budget.

3. 40-man roster moves incoming:

The Tigers, Diamondbacks, and Cardinals worked out deals with free agent right-handers Kenley Jansen, Merrill Kelly, and Dustin May, respectively, over the weekend. All three of those clubs have 40-man rosters already at capacity, however, and as a result each club will need to make a corresponding move the clears space on the 40-man before it can bring its new player into the fold officially. Those corresponding moves could be as simple as designating a player for assignment, though it’s also possible that a trade could be worked out that creates additional breathing room on the roster by trading someone already on the 40-man for non-roster prospects. That could be a particularly realistic route for the Cardinals, who are known to be engaging in trade conversations regarding a number of players on their roster as they enter a rebuilding period.
