Mets Interested In Willson Contreras, Lars Nootbaar
The Mets have grabbed headlines for the moves they haven’t made this offseason, namely watching Pete Alonso sign with Baltimore and Edwin Diaz head to Los Angeles. The club is actively working to add on the offensive side, though, with the Cardinals as a potential trade partner. Will Sammon of The Athletic reports the Mets have interest in outfielder Lars Nootbaar, while John Denton of MLB.com reports New York reached out about Willson Contreras.
Neither Contreras nor Nootbaar would replace the Alonso-sized void in the lineup, but both would fill holes in the roster. Contreras could slot right into Alonso’s vacated spot at first base, while Nootbaar would help cover the gap left by Brandon Nimmo, who was dealt to the Rangers.
Contreras and Nootbaar are just a couple of the many Cardinals popping up in trade conversations. Brendan Donovan is drawing widespread interest. JoJo Romero has intrigued several teams. Nolan Arenado has been a trade candidate for multiple seasons. Nolan Gorman and Alec Burleson have been mentioned as possibly getting moved. Despite the interest around the league, nothing materialized during the Winter Meetings. “To some degree, it’s binary — either you have something or you don’t. Right now, we don’t,” president of baseball operations Chaim Bloom told reporters.
As Anthony Franco pointed out in this piece about replacing Alonso (Front Office subscription required), Contreras would be the most straightforward fit in the trade market. He has a no-trade clause, but is reportedly open to waiving it. Contreras is under contract for the next two seasons, with a club option for 2028. He’s slated to make $18MM next season and $18.5MM in 2027. The price tag isn’t exorbitant for his level of production, but it might be too costly for the rebuilding Cardinals to keep around.
Contreras has been a firmly above-average bat in his three seasons with St. Louis. He’s posted a wRC+ of at least 124 in each campaign. Contreras has a pair of 20-homer campaigns as a Cardinal, and the lone miss was his most productive year with the team. He hit 15 home runs in just 84 games in 2024, but a broken finger ended his season in late June.
The 33-year-old Contreras hasn’t missed a beat as he’s entered his 30s. His profile has arguably looked even better under the hood in recent years. Contreras posted a career-high 49% hard-hit rate this past season. He ranked 95th percentile in bat speed. Contreras has been one of the hardest swingers in the game since bat speed data became widely available.
The Nootbaar fit isn’t as seamless, largely due to availability. The outfielder had surgery on both heels in October and may miss the beginning of the 2026 season. The procedure may have already removed one team from contention for Nootbaar’s services. Replacing Nimmo’s strong on-base skills and steady all-around production will be difficult, but so will finding another option to match his durability. The former Met has topped 150 games in four straight seasons. The oft-injured Nootbaar has maxed out at 135 games in a season, and that came this past year, which ended with the double-heel surgery.
Nootbaar has generally been productive when available. He’s routinely posted well above-average walk rates and solid slugging numbers. Nootbaar is typically good for a dozen home runs, a handful of steals, and a respectable OBP. The 2025 season was a healthy one, but Nootbaar declined in production. He slashed just .234/.325/.361, recording his first sub-100 wRC+ since his rookie season in 2021.

Braves Sign Mike Yastrzemski
The Braves announced a two-year, $23MM contract with outfielder Mike Yastrzemski. He’ll make $9MM in 2016 and $10MM in 2027 and is guaranteed a $4MM buyout on a 2028 club option valued at $7MM. Yastrzemski is represented by Jack Toffey Sports Management. Atlanta designated outfielder Michael Siani for assignment in a corresponding move.
Atlanta hadn’t waded too far into the free agent market outside of re-signing closer Raisel Iglesias. The club now improves its outfield/DH mix by bringing in Yastrzemski. The lefty-swinging veteran finished last season with the Royals after getting dealt by the Giants at the trade deadline. After spending his first six seasons in San Francisco, Yastrzemski will now be on his third team in the calendar year.
Before the move, the Braves were looking at a pair of speed-first options in holdover Eli White and waiver claim Siani as their bench outfielders behind the trio of Ronald Acuna Jr., Michael Harris II, and Jurickson Profar. Yastrzemski gives them a more viable offensive contributor as the fourth outfielder. Braves president of baseball operations Alex Anthopoulos recently mentioned he preferred to leave the DH spot open and split the duties between multiple players. Yastrzemski figures to factor into that equation against right-handed pitching, grabbing left field reps with Profar moving to DH.
Yastrzemski was having one of his weakest offensive campaigns with the Giants prior to getting traded. He had managed just eight home runs and a career-low .355 SLG across 97 games. The move to Kansas City flipped his season, as he quickly emerged as a crucial top-of-the-order contributor. Yastrzemski slugged nine home runs in 50 games with the Royals, while walking more than he struck out. He capped off his season with a two-homer game against the Athletics.
The 35-year-old Yastrzemski didn’t reach the big leagues until age 28. He immediately made an impact in the power department, swatting 21 home runs in 411 plate appearances as a rookie. Yastrzemski earned near-regular playing time over the next five seasons, providing solid production against righties while typically sitting against lefties. He tended to strike out at an above-average rate, but still finished with a wRC+ of at least 106 in all but one season with the Giants.
Yastrzemski has spent the majority of his time in right field, though he has experience at all three outfield spots. He made six starts in left field, five starts in center field, and 29 starts in right field during his brief stint with the Royals. Yastrzemski graded out as a neutral fielder by Outs Above Average. His range received poor marks, but he offered value with his arm, per Statcast.
Kansas City was reportedly interested in a Yastrzemski reunion. Given his strong two months for the team, it made sense the Royals would look to bring him back. The club is currently short on proven outfielders, with Jac Caglianone, Kyle Isbel, and John Rave penciled in as starters. Considering that the trio is entirely left-handed, targeting a righty bat might be a better fit for Kansas City.
Robert Murray of FanSided first reported the Braves were nearing a deal with Yastrzemski. Jon Heyman of The New York Post first had the two-year, $23MM guarantee and the option.
Blue Jays Finalize 2026 Coaching Staff
TODAY: The Blue Jays officially announced their 2026 coaching staff. Duncan will be a Major League field coordinator, Atkinson will be an assistant hitting coach, and Butera will have the general role of Major League coach. Bannon believes Butera and Duncan will also share in bench coach duties with other members of the staff, as the Jays plan to divvy up Mattingly’s responsibilities rather than name a full-time bench coach.
DECEMBER 9: The Blue Jays have reportedly made multiple additions to manager John Schneider’s staff. Former catcher Drew Butera is expected to be in the dugout next season, reports Shi Davidi of Sportsnet. He’ll be joined by Eric Duncan and Cody Atkinson, reports Mitch Bannon of The Athletic.
Butera was a catching instructor with the White Sox for the past two seasons. He had previously been a bullpen catcher and catching coach with the Angels. Butera spent 12 seasons behind the plate in the big leagues. He played for five different teams, with his longest stints coming with the Royals and Twins. Butera won a World Series ring with Kansas City in 2015.
Duncan served as Toronto’s director of position player development in 2024, per Bannon. His first MLB coaching gig was with the Marlins as an assistant hitting coach in 2019. He also worked as a quality control coach with the team. Duncan was a first-round pick by the Yankees in 2003. He topped out at Triple-A as a player. New York hired him as a minor league coach in 2015.
Atkinson had been the Rangers’ minor league hitting director, per Bannon. He’s been in charge of the organization’s minor league hitting program since 2019, according to MLB.com. It’s unclear which roles the trio will fill, though it’s fair to assume Butera will contribute in the catching department, with Duncan and Atkinson helping out on the hitting side. The only news prior to today regarding Schneider’s staff had been the departure of bench coach Don Mattingly, who is being pursued by the Phillies.

Red Sox Checked In On Corey Seager
The Red Sox have had talks with the Rangers about a Corey Seager deal, reports Tim Healey and Alex Speier of the Boston Globe. Seager joins a growing list of Boston trade targets that includes Ketel Marte, Isaac Paredes, and Brendan Donovan. The club has also been connected to free agentsBo Bichette, Pete Alonso, and Eugenio Suarez. WEEI’s Rob Bradford reports there isn’t any momentum regarding Boston’s pursuit of Seager.
While the club has been connected to several players in the trade market, chief baseball officer Craig Breslow admitted some discussions have been slow to progress. “In a lot of the conversations that we’ve had, a number of teams have conveyed that they’re very comfortable holding onto their players, as are we,” Breslow said. “So that does add a little bit of a layer of difficulty to try to make these things work.”
Seager delivered a typical season in 2025, providing stellar offensive production in between IL stints. The 31-year-old notched a 138 wRC+ across 102 games. Seager fell short of 30 home runs for the first time as a Ranger, largely due to missing time with a hamstring strain (twice) and an appendectomy. His 445 plate appearances were his fewest since his final year with the Dodgers in 2021.
Texas landed Seager on a massive 10-year, $325MM deal ahead of the 2022 season. He’s been an integral part of the lineup over the past four seasons and led the team to a World Series win in 2023. Seager finished second in AL MVP voting that year, but still went home with individual hardware after securing World Series MVP honors.
Seager will make $31MM in each of the next six seasons. There have been whispers that Texas would be trimming payroll this offseason. The team already chose to non-tender Adolis García and Jonah Heim instead of paying their arbitration price tags. The Rangers also traded Marcus Semien, who had three years and $72MM remaining on his contract, but the deal brought back Brandon Nimmo, who is slated to make $101.25MM through the 2030 season. The Mets did toss in $5MM as part of the trade.
Texas could use some help in the rotation and the bullpen. Linking up with Boston in a trade could help cheaply patch those holes. Breslow has said the team is willing to deal controllable starting pitching. Boston bolstered the rotation by adding Sonny Gray and Johan Oviedo via trade. Garrett Crochet and Brayan Bello are locked into rotation spots, which leaves little room for youngsters Payton Tolle, Connelly Early, and Hunter Dobbins. Veterans Patrick Sandoval and Kutter Crawford are also expected to be back healthy.
Trevor Story served as Boston’s primary shortstop last season. After multiple injury-riddled seasons, the former Rockie came through with a resurgent year. Story launched 25 home runs and stole a career-high 31 bases. He remains on the books for $25MM in each of the next two seasons. The contract also includes a $25MM club option for 2028. Story exclusively played second base in his first year in Boston, with Xander Bogaerts holding down shortstop. He could slide back to the keystone if the club acquires Seager, though that would require some reshuffling with Ceddanne Rafaela and potentially others. Center fielder Jarren Duran has been the subject of frequent trade talks, and his departure would clear a spot for Rafaela in the outfield.

Orioles Made $150MM Offer To Kyle Schwarber
The first major free agent chip fell this morning with Kyle Schwarber returning to Philadelphia on a five-year, $150MM deal. The reunion seemed likely from the start, though the slugger had several other suitors, including at least one willing to match the $150MM price tag. Ken Rosenthal of The Athletic reported the Orioles offered Schwarber the same deal he ultimately accepted with the Phillies.
President of baseball operations Mike Elias has made it clear the team is looking for an impact bat, even after acquiring Taylor Ward. The Orioles still have a significant gap between last year’s payroll and their financial outlook for next season, giving them the potential flexibility for a large expenditure. The club has already spent some money this offseason, though it’s all gone to the bullpen. Baltimore added Ryan Helsley on a two-year, $28MM deal and picked up the $9MM option on Andrew Kittredge after acquiring him from the Cubs.
Camden Yards would’ve been a fun fit for Schwarber. Statcast’s Park Factors ranked it as the third-best home run venue for left-handed hitters. Citizens Bank Park tops the list, so Schwarber isn’t missing out on much by spurning the Orioles.
Baltimore will now turn its attention to the remaining free agent bats, including Pete Alonso. The Orioles and Red Sox are expected to meet face-to-face with the former Met this week. Baltimore’s lineup is strong up the middle and behind the plate, but there should be room to make additions at the corners and DH. Youngsters Samuel Basallo and Coby Mayo will likely factor in at first base and DH, but they wouldn’t preclude the club from adding a player like Alonso. Rosenthal noted the club is also considering Kyle Tucker in its pursuit of an elite hitter.
Pittsburgh’s interest in Schwarber was met with skepticism, but the club came through with a legitimate offer. Rosenthal had the Pirates’ proposal at four years and $120MM, while Alex Stumpf of MLB.com reported the club offered $125MM. Pittsburgh’s offer either met or exceeded the Philles’ deal in terms of average annual value, according to those reports. The fifth year could’ve been the trump card, but it’s hard to scoff at an offer worth upwards of $30MM per season.
Landing Schwarber for anywhere near those reported numbers would have easily set a franchise record for a free agent signing. The current mark is $39MM for Francisco Liriano in 2014. Pittsburgh’s last multi-year signing was a three-year deal with Ivan Nova heading into the 2017 campaign.
GM Ben Cherington previously touted the team’s increased financial flexibility this offseason, and the front office is doing what it can to make a big splash. Pittsburgh was also in on Josh Naylor before he re-signed with Seattle. Stumpf noted that the club will now turn its attention to another former Mariner, Jorge Polanco. The Pirates are expected to have an offer to him soon, per Stumpf.
Cincinnati had been connected to Schwarber given its proximity to his hometown. Rosenthal had the Reds’ offer at five years, but closer to $125MM. C. Trent Rosecrans of The Athletic reported that Schwarber and his wife met with Cincinnati brass before Thanksgiving.
Unlike the Orioles and Pirates, the Reds are not expected to redirect the money offered to Schwarber elsewhere. Their pursuit of the slugger was driven by the idea that signing him would benefit ticket sales, per Rosenthal. Schwarber is from Middletown, Ohio, less than an hour from Great American Ball Park.

White Sox Win Draft Lottery
The White Sox have won the MLB Draft Lottery and earned the first pick. They had the best odds to land the top spot at 27.73%. Chicago will be followed by the Rays and Twins.
Here’s the first round order:
- White Sox
- Rays
- Twins
- Giants
- Pirates
- Royals
- Orioles
- Athletics
- Braves
- Rockies
- Nationals
- Angels
- Cardinals
- Marlins
- Diamondbacks
- Rangers
- Astros
- Reds
- Guardians
- Red Sox
- Padres
- Tigers
- Cubs
- Mariners
- Brewers
This is the fourth edition of the draft lottery. The system was introduced through the most recent collective bargaining agreement to deemphasize tanking. The top six overall selections are determined by the lottery. There are limitations on picking in the lottery in multiple years. Clubs that aren’t revenue sharing recipients are barred from getting lottery picks in consecutive years, and no team can pick in the lottery three years in a row. Those parameters knocked out the Rockies, Nationals, and Angels this year.
Record still has weight when it comes to the draft order, which propelled the 60-win White Sox to the top of the odds board for the No. 1 selection. The Twins had the second-highest odds to earn the first pick at 22.18%, followed by the Pirates at 16.81%. No other team had better than a 10% chance to win the lottery.
This is the second time the team with the best odds received the top pick. The Pirates, along with two other teams, had the top odds when they won the 2022 lottery and earned the right to select Paul Skenes. The Guardians were a long shot to win in 2023, and the Nationals had the fourth-best odds in 2024.
The Giants and Royals came out as big winners, finding themselves with lottery picks after winning 80+ games last season. San Francisco went .500 and finished just two games out of a Wild Card spot. Kansas City ended up above .500 for the second straight year.
The Cardinals had a significant drop, falling from the eighth-best odds down to the 13th pick. The Marlins also fell five spots, going from the ninth-best odds to the 14th pick.
UCLA shortstop Roch Cholowsky is widely regarded as the top prospect in the 2026 draft. High school shortstop Grady Emerson and Alabama infielder Justin Lebron are candidates to be selected with early picks.
Pirates Made Four-Year Offer To Kyle Schwarber
TODAY: In a follow-up to his original report, Rosenthal specified that the Pirates’ four-year offer was worth roughly $120MM.
DECEMBER 7: Ken Rosenthal of The Athletic reported the Pirates have made a four-year offer to free agent slugger Kyle Schwarber. Rosenthal adds that the proposal is likely worth more than $100MM.
The club has been mentioned multiple times as Schwarber’s market takes shape this offseason. He’s not the only big bat they’ve been in on, as they also pursued Josh Naylor before he re-signed with Seattle. Rosenthal notes the Pirates remain an unlikely landing spot for Schwarber, though GM Ben Cherington previously said the team has “more [financial] flexibility” than they’ve had in prior offseasons.
Schwarber had a career year at just the right time. As a pending free agent, he launched 56 home runs to lead the National League. He posted a career-high 152 wRC+, which ranked behind only Shohei Ohtani and Juan Soto in the NL. Schwarber had a strong case for NL MVP if not for the two-way dominance of Ohtani.
While the free agent market features prodigious power hitters like Pete Alonso and Eugenio Suarez, plus high-upside thumpers like Munetaka Murakami, it’s hard to find an available slugger who matches Schwarber’s consistency. The 32-year-old has hit at least 38 home runs in all four seasons with Philadelphia. He’s topped 100 runs in each campaign, while averaging more than 108 RBI per year. Schwarber had a minimum stint on the IL for a hamstring strain in 2024, but has otherwise been healthy, reaching 150 games every season in Philly.
The note that the Pirates’ offer to Schwarber is in the nine figures isn’t a surprise. We had him getting $135MM over five years in our Top 50 Free Agents article. If Pittsburgh were to lure Schwarber on that kind of commitment, it would be a historic deal for the franchise. As Rosenthal points out, the club’s record free agent contract is $39MM to Francisco Liriano back in 2014. Cherington and his cohorts did give Bryan Reynolds a $100MM deal, though it was a contract extension.
Pittsburgh’s largest outlay in free agency last offseason was $5.25MM to Andrew Heaney. The club has spent more than $10MM just once this decade, giving Aroldis Chapman $10.5MM prior to the 2024 season. The Pirates haven’t handed out a multi-year contract in free agency since re-signing Ivan Nova for three years and $26MM ahead of the 2017 season. They also grabbed Daniel Hudson for two years and $11MM that offseason.
RosterResource has Pittsburgh’s payroll at $64MM for 2026. The team was at $87MM in each of the past two seasons. Nearly half of next year’s payroll will be going to Reynolds and Mitch Keller, who signed a five-year, $77MM extension in 2024.
A return to Philadelphia is among the most likely outcomes for Schwarber, though the two sides aren’t on the same page just yet. Boston, Baltimore, and San Francisco have also been mentioned as possible destinations. Cincinnati, Schwarber’s hometown team, is said to be in the mix.

Dodgers Notes: Hernandez, Betts, Edman
Outfielder Teoscar Hernandez has come up in trade talks recently, though both manager Dave Roberts and general manager Brandon Gomes shot down the notion of moving the veteran. “That doesn’t feel likely,” Gomes told reporters, including Jack Harris of the Los Angeles Times. “Obviously, you can never say never on those types of things. I know that’s come up [in reports]. But that’s not something we anticipate at all.”
Hernandez is heading into the second season of a three-year, $66MM deal. He’s coming off a down 2025 campaign in which he provided close to league-average results by wRC+. The veteran slashed .247/.284/.454 with 25 home runs as LA’s primary right fielder. Hernandez posted a decent .788 OPS in the postseason.
The 33-year-old Hernandez spent time in center field early in his Toronto tenure, though those days are long gone. He might be better suited as a DH at this point, but that spot is obviously taken in LA. Hernandez has delivered back-to-back brutal seasons in the field in terms of Outs Above Average, posting a -10 in 2024 and a -9 this past year. Roberts seems to disagree with Statcast’s assessment of Hernandez’s defense, calling his play “at least average” in right field, though he indicated a change could be possible. “I do think that with the versatility [of our roster] and how we potentially shape this roster, there’s some options,” Roberts said. “But right now, he’s our right fielder.”
One player who won’t be an option to replace Hernandez in right field is Mookie Betts. Roberts confirmed the versatile Betts will remain at shortstop next season. “He put a lot of time in at shortstop, a lot of bandwidth, and it certainly worked because he was a lockdown shortstop for us,” Roberts told reporters, including Katie Woo of The Athletic. Betts started 148 games at short last season.
Betts is a six-time Gold Glove award winner in the outfield, but he’s moved to the dirt the past two seasons. He split his time between second base and shortstop in 2024, before moving full-time to the latter spot in 2025. Betts earned modest defensive grades when he first moved to the infield, but posted strong numbers last season. Defensive Runs Saved was especially kind to Betts, giving him a +17 mark.
Some of the roster versatility Roberts mentioned might also take a hit after Gomes provided a health update on Tommy Edman. The GM said Edman recently underwent a debridement procedure to address his ankle injury. Gomes added that the infielder/outfielder would likely be limited heading into Spring Training, and the club doesn’t expect the recovery to “affect a meaningful part of the season.” The phrasing of that timeline cast a bit of doubt on Edman’s availability to start the year.
Edman hit the injured list with ankle inflammation in May. He returned after only missing a few weeks of action, but went down again with an ankle sprain in August. Edman made it back for the final few weeks of the regular season. He started every postseason game for LA, primarily playing second base, along with a couple of starts in center field. Edman also missed significant time in 2024 with a wrist injury.
The surgery could potentially help Edman bounce back offensively next season. He posted a career-worst 81 wRC+ over 97 games in 2025. More concerning, he managed just three steals. After three consecutive seasons of at least 25 thefts with St. Louis, Edman has totaled nine steals across his two years in LA.

White Sox Interested In Pete Fairbanks
The list of suitors for free agent reliever Pete Fairbanks continues to grow. Scott Merkin of MLB.com reports that the White Sox are interested in the veteran right-hander. Chicago joins the Diamondbacks, Tigers, Marlins, Blue Jays, and Dodgers as teams connected to Fairbanks.
Tampa Bay declined its $11MM option on Fairbanks back in November. The 31-year-old piled up 75 saves over the past three seasons with the club. Fairbanks posted a strong 2.83 ERA over 61 appearances in 2025, setting a career high in innings by 15 frames. The price tag seemed reasonable for Fairbanks given his recent production, though it ended up being too much for the cost-conscious Rays.
Fairbanks cruised through this past season without any health issues for the first time since the shortened 2020 campaign. Over the previous four years, he had missed time with rotator cuff, shoulder, lat, forearm, and hip injuries. Fairbanks also dealt with a nerve-related issue in 2024. After his fastball sat at 99 mph in 2023, it’s been in the 97 mph range over the past two years.
Even with the frequent IL stints, Fairbanks was a valuable member of Tampa Bay’s bullpen during his tenure. He posted a 3.19 ERA over 265 1/3 innings with the club. Fairbanks was virtually unhittable for stretches, including a two-year run from 2022 to 2023 where opponents hit .155 and .163 against him, respectively. Sending Nick Solak to Texas straight up for Fairbanks before the reliever found his footing in the big leagues certainly paid off for Tampa Bay.
The White Sox bullpen had the fifth-worst SIERA and the third-worst xFIP last season. The closer role was a moving target, with nine different relievers recording a save. Jordan Leasure led the way with seven saves and would likely be Chicago’s closer if the season started today, though he would likely be supplanted by Fairbanks or any other notable free agent acquisition. No White Sox reliever has recorded double-digit saves since 2022 (Liam Hendriks with 37).
Chicago shelled out $24MM for Kendall Graveman and $17MM for Joe Kelly ahead of the 2022 season. Since then, the club has been hesitant to spend on relievers (or any other position). The most expensive bullpen addition over the past three seasons was John Brebbia on a one-year, $5.5MM deal in 2024. The White Sox’s only reliever signing last offseason was Bryse Wilson, who got a one-year, $1.05MM pact.

Mariners Not Planning To Trade Luis Castillo
The Mariners were willing to listen to offers for Luis Castillo at this time last year, but the right-hander ultimately remained with Seattle. The club doesn’t intend to shop Castillo during this year’s winter meetings, reports Adam Jude of the Seattle Times.
The 32-year-old Castillo delivered steady results last season, pitching to a 3.54 ERA over 32 starts. He topped 175 innings for the third straight year. Castillo’s strikeout rate fell to a career-low 21.7%, but he countered the downturn with a career-best 6.2% walk rate. The veteran has now improved his walk rate in each of the past four seasons.
Castillo has two years and $45.5MM remaining on the five-year, $108MM deal he signed with Seattle back in 2023. The contract also includes a vesting option for 2028, which is triggered if Castillo reaches 180 innings in 2027. He’ll easily be the Mariners’ highest-paid player next season, though it’s a reasonable commitment for Castillo’s reliable innings.
Seattle acquired Castillo from Cincinnati at the 2022 trade deadline for a package of Noelvi Marte, Edwin Arroyo, Levi Stoudt, and Andrew Moore. Marte hasn’t completely lived up to his lofty prospect pedigree, but he provided meaningful contributions at the big-league level last season. Arroyo is among the club’s top infield prospects and could reach the majors as soon as 2026. Still, the deal has worked out well for the Mariners.
Castillo has been remarkably consistent with Seattle, recording an ERA between 3.34 and 3.64 in his three full campaigns with the team. His approach has changed significantly as a Mariner, with an increased focus on his fastball/slider instead of the changeup. Castillo boasted one of the more effective changeups in the league while in Cincinnati, and he used it as his primary pitch from 2019 to 2021. With Seattle, he’s pushed the offering behind his four-seamer, sinker, and slider in terms of usage. The changeup has easily been Castillo’s least-effective pitch by Run Value since he joined the Mariners. His fastball has emerged as a dominant pitch, notching a Run Value of at least 12 in four straight years.
Seattle’s standout starting rotation struggled with injuries last season. George Kirby and Logan Gilbert both missed extended stretches. Bryan Woo, who had largely been healthy for the first time, went down in September, but made it back for the ALCS. With Bryce Miller expected to avoid elbow surgery, the group should be back to full strength next year.
The Mariners have been on the offensive this offseason, re-signing Josh Naylor and swapping Harry Ford for Jose A. Ferrer. Even with Ferrer joining the squad, Seattle isn’t done making tweaks to the bullpen, per president of baseball operations Jerry Dipoto. “We will continue to add to our bullpen, in all different ways, like we always have,” Dipoto told reporters, including Jude. Dipoto mentioned that the team has been in touch with multiple veteran relievers and expects a deal to get done.
Led by Andres Munoz, the Mariners’ bullpen ranked eighth in SIERA last season. Ferrer will give the team a hard thrower from the left side, joining Matt Brash as a setup option ahead of Munoz. With Emerson Hancock preparing as a starter, Seattle could target a swingman on the open market. Another lefty alongside Ferrer and Gabe Speier could also make sense.
