Giants, Max Stassi Agree To Minor League Deal

By | at

The Giants agreed to a minor league contract with Max Stassi, as first reported by Just Baseball’s Aram Leighton (on X) and subsequently reflected on the catcher’s MLB.com transaction log. It’s likely the Wasserman client will get a non-roster invite to big league camp.

Stassi hasn’t appeared in the majors since 2022. He started the ’23 season on the injured list with a left hip problem and was eventually transferred to the restricted list as he attended to a family matter. (The Stassis later announced that their son was born prematurely and spent weeks in intensive care.) He was traded twice last offseason, going from the Angels to the Braves to the White Sox in a chain of salary-driven moves.

The Sox intended to give Stassi a look as their backup catcher, but he reaggravated his hip injury and underwent season-ending surgery in June. Chicago paid a $500K buyout in lieu of a $7.5MM option, ending his White Sox tenure without any games. The consecutive lost seasons made it apparent he’d need to accept a minor league contract.

Stassi’s most recent healthy season was a disappointment. He hit .180/.267/.303 across 375 plate appearances in 2022. The two preceding years were far more impressive. Stassi combined for a .250/.333/.452 slash between 2020-21. He rated as an above-average receiver and looked like a late-blooming #1 catcher. The Halos signed Stassi to a $17.5MM extension in Spring Training 2022, though his numbers fell off almost immediately thereafter.

Patrick Bailey is locked in as San Francisco’s starting catcher. The backup job could be up for grabs. Tom Murphy had an injury-ruined season in year one of a two-year free agent deal. Blake Sabol is also on the 40-man roster but carries a questionable defensive profile.

Jake Cave Signs With KBO’s Doosan Bears

By | at

The Doosan Bears of the Korea Baseball Organization announced this week that they’ve signed outfielder/first baseman Jake Cave to a one-year, $1MM contract (hat tip to Dan Kurtz of MyKBO.net). Cave, a client of the Ballengee Group, will head overseas for the first time in his career and earn the maximum salary for a first-year foreign player in the KBO.

A veteran of seven big league seasons, Cave spent the 2024 season with the Rockies and hit .251/.290/.396 with seven home runs in 346 plate appearances. The Rockies passed Cave through waivers following the season, and he elected free agency once he went unclaimed.

Cave, 32 next month, has spent the bulk of his career with the Twins but was also with the Phillies in 2023 and the Rox this past season. Overall, he’s a lifetime .236/.292/.400 hitter in the majors (85 wRC+). Contact, or a lack thereof, has been a notable issue for him. Cave has fanned in 30.8% of his career plate appearances. He does have a knack for making decent contact when he puts the ball in play, with nearly 25% of his career batted balls being line drives. That’s several percentage points north of league-average, but his lack of contact offsets that penchant for solid contact.

Cave has logged more than 1000 big league innings at each of the three outfield spots. The Phillies also gave him 122 innings at first base in 2023. He spent a good bit of time in center field with Minnesota early in his career but has worked primarily in the corners in recent seasons, drawing solid grades for his glovework. Statcast credits him with above-average sprint speed and above-average arm strength in the outfield, ranking him in the 60th and 61st percentile of MLB players this past season, respectively.

As Jee-ho Yoo of South Korea’s Yonhap News Agency points out, Cave will round out the Bears’ international signings for the year. KBO clubs are permitted to carry three foreign players, and Doosan already signed pitchers Cole Irvin and Thomas Hatch earlier in the offseason.

KBO’s Kiwoom Heroes Sign Kenny Rosenberg

By | at

The Kiwoom Heroes of the Korea Baseball Organization announced their trio of foreign-born players for the 2025 season. The Heroes signed outfielders Yasiel Puig ($1MM) and Ruben Cardenas ($450K salary with $150K in incentives) and left-hander Kenny Rosenberg ($700K salary with $100K in incentives). The deals were relayed (on X) by Dan Kurtz of MyKBO.net.

Rosenberg is the only one of the trio who appeared in the majors in 2024. The 29-year-old southpaw pitched in seven games for the Angels, allowing an even 6.00 ERA across 24 innings. It was the third straight season in which Rosenberg made a handful of appearances for the Halos. He worked as a depth option for the rotation or low-leverage relief and combined for a 4.66 mark over 67 2/3 frames.

Los Angeles released Rosenberg within the first few days of the offseason. This will be the first overseas stint for the Cal State Northridge product. Rosenberg had previously split his eight-year professional career between the Rays and Angels organizations. He has a solid Triple-A track record. Over parts of five seasons at the top minor league level, he carries a 4.10 ERA while striking out a quarter of opposing hitters.

Puig hasn’t appeared in the majors since 2019. He played the 2022 season in Korea with the Heroes. Puig spent the ’24 campaign in Mexico. Cardenas spent most of this this year in Triple-A. He divided his time between the Rays’ and Phillies’ systems but didn’t get a big league call. He signed with the KBO’s Samsung Lions late in the year but only made seven appearances. The Cal State Fullerton product should get a more significant opportunity for the Heroes.

Guardians Re-Sign George Valera To Minor League Deal

By | at

The Guardians announced they’ve brought back former top outfield prospect George Valera on a minor league deal. He’ll get an invite to big league Spring Training as a non-roster player.

Valera, 24, was a notable international amateur signee back in 2017. He raked in the low minors and got to Double-A at age 20. Valera’s offensive promise made him one of Cleveland’s most touted minor leaguers. He landed in the back half of Baseball America’s overall Top 100 prospects entering both 2022 and ’23. The Guardians made the easy call to put him on the 40-man roster after the ’21 season rather than expose him to the Rule 5 draft.

The left-handed hitter’s stock has dropped significantly over the past couple years. While Valera had an impressive age-21 season at Double-A, he hasn’t carried that over to the top minor league level. Over parts of three seasons with Triple-A Columbus, he owns a middling .229/.336/.424 batting line. He has walked at a strong 13.5% clip but gone down on strikes in 26.7% of his 865 Triple-A plate appearances.

A litany of injuries hasn’t done him any favors. Valera has missed time with hamstring issues and underwent surgery to repair a hamate fracture in his right hand over the 2022-23 offseason. His ’24 campaign was cut short in September, as he injured his right knee and required patellar tendon surgery. That came with at least a six-month recovery timeline, so his availability for Spring Training games is in question.

Cleveland no longer felt they could carry that profile on their 40-man roster. They designated Valera for assignment last week as they added four players to the roster to ensure they wouldn’t lose them in the Rule 5 draft. The non-tender deadline allowed the Guards to cut Valera loose without putting him on waivers. He had a few days to gauge the market but seemingly didn’t find any team springing to offer him a 40-man spot. Valera returns to the only organization he’s known but will need to play his way back onto the roster as he tries to reach the majors.

KBO’s Samsung Lions Re-Sign Lewin Díaz, Denyi Reyes

By | at

The Samsung Lions of the KBO League announced that they have re-signed first baseman Lewin Díaz and right-hander Denyi Reyes, per Dan Kurtz of MyKBO.net and Jiheon Pae (X link). Díaz will get a $100K signing bonus, a $500K salary and $200K of incentives while Reyes gets a $200K signing bonus, $700K salary and $300K of incentives.

Díaz, now 28, was a very popular player during his time in North America, though without getting an extended big league opportunity. He started his major league career with the Marlins but only got limited looks in the three years from 2020 to 2022.

Having exhausted his options after that stretch, his grip on his roster spot became tenuous and he was designated for assignment by the Fish. Before the 2023 season started, he went to the Pirates, Orioles, Atlanta and Orioles again via waivers or cash trades. The O’s did eventually run him through waivers and didn’t call him up in 2023.

In general, Díaz has performed well everywhere except the majors. He hit .181/.227/.340 in his brief looks in the big leagues but had a much nicer line of .258/.340/.479 at the Triple-A level over the 2021-2023 seasons. He is also considered a strong defender at first base, so that made for an intriguing combination, likely why he kept getting so much attention.

He went to the Mexican League in 2024 and put up a huge slash of .376/.452/.647 in 75 games there. He then got a deal with the Lions in the middle of August, with a strong .282/.331/.518 line in 29 games in Korea, seemingly enough to convince the Lions to bring him back.

Reyes, now 28, was a similarly fringe roster player during his time in the affiliated ball. He got to make three appearances for the 2022 Orioles and then got into nine games for the 2023 Mets, posting a 6.26 earned run average in his 27 1/3 innings.

He posted some intriguing rate stats in the minors but was victimized by the long ball. From 2021 to 2023, he threw 209 1/3 innings on the farm with a 21.4% strikeout rate that was close to average and 5.7% walk rate that was quite strong. But thanks to 47 balls leaving the yard in that time, he had a 5.59 ERA.

Reyes signed with the Lions going into 2024 and went on to have a solid year, with the groundball-heavy league seeming to be a good fit for him. He logged 144 innings over 26 starts with a 3.81 ERA, 18.5% strikeout rate, 4.9% walk rate, 62.3% ground ball rate and 15 homers allowed. The Lions were evidently pleased with that performance and will bring him back for 2025.

Both players are still relatively young and could try to return to MLB in the future if they continue to have good results overseas, as players like Erick Fedde or Eric Thames have done. For now, they will lock in some decent money that’s in the vicinity of the MLB minimum, which will be $760K next year.

Brewers, Thomas Pannone Agree To Minor League Deal

By | at

The Brewers agreed to a minor league deal with lefty Thomas Pannone, reports Todd Rosiak of the Milwaukee Journal-Sentinel. The BHSC client will be in major league camp as a non-roster invitee to spring training in 2025.

It’ll be the second Brewers stint of Pannone’s career. He was also with the organization in 2023. While the 30-year-old’s broader track record in Triple-A doesn’t necessarily stand out, he’s been sharp against non-MLB competition in recent seasons. Pannone tossed 53 1/3 innings of 2.70 ERA ball with the Brewers’ Triple-A club in 2023, and he also spent parts of the 2022-23 seasons with the KBO’s Kia Tigers, pitching to a combined 3.49 ERA in 165 innings across those two seasons. Most recently, Pannone hurled 152 1/3 innings of 3.54 ERA ball between the Triple-A affiliates for the Cubs and Yankees in 2024. He fanned 21.9% of opponents against a 5.9% walk rate this past season.

All of that should allow Pannone to head to camp with the Brewers and compete for a rotation spot or long relief role. He’s stretched out and built up, meaning workload wouldn’t be an issue if the Brewers need to utilize him as a starter between Nashville and Milwaukee. (Notably, he’s out of minor league options, so if he’s added to the 40-man at any point, he’d have to stick or else be placed on waivers.)

For a Brewers club that is currently light on rotation depth, adding a lefty who’s pitched well for the past three seasons in the upper minors and in the KBO makes good sense. At the moment, Milwaukee’s rotation likely includes Freddy Peralta, Brandon Woodruff (likely on an innings limit after missing 2024 due to shoulder surgery), Aaron Civale, Tobias Myers and one of Aaron Ashby or DL Hall. That group could change, of course, depending on how the rest of the offseason plays out. Each of Myers, Ashby and Hall can be optioned. Civale has been a speculative trade candidate (as is the case with most Brewers veterans when they’re down to one final season of club control remaining). Lefty Robert Gasser could join the bunch late in 2025, but he’s recovering from UCL surgery performed in June.

Twins Sign Alex Speas To Minor League Contract

By | at

The Twins have signed right-hander Alex Speas, as initially announced by Speas’ agency, Munger English Sports Management (X link).  Bobby Nightengale of the Minneapolis Star Tribune confirmed that it is a minor league deal, and SKOR North’s Darren Wolfson adds that Speas will get an invitation to the Twins’ big league Spring Training camp.

Minnesota becomes Speas’ sixth different MLB organization within the last 14 months.  A second-round pick for the Rangers in the 2016 draft, Speas spent his entire pro career with Texas until October 2023, when the White Sox claimed the righty off waivers.  The A’s traded for Speas last April, and he subsequently went to the Astros and then the Red Sox on other waiver claims after being designated for assignment.  Boston DFA’ed Speas as well and outrighted him off their 40-man roster in August, and Speas finished out the season pitching with Triple-A Worcester.

Speas’ transactional whirlwind resulted in just a single game at the Major League level, as he tossed two relief innings for the Astros on May 31 (in a 6-1 loss to his new team, the Twins).  Speas’ overall MLB resume consists of four games, as he first reached the Show with three appearances for Texas during the 2023 season.  Speas has a 9.00 ERA in that small sample size as a big leaguer, and an 8.69 ERA in 58 career innings at the Triple-A level.

Those struggles can be directly traced to a garish 23.05% walk rate, as Speas’ inability to find the plate has left him unable to claim any sort of foothold in the majors.  Since Speas has a 28.13% strikeout rate at Triple-A and a fastball in the 100mph range, it is easy to see why teams keep taking chances on Speas, and the Twins will become the latest club to see if it can harness Speas’ control and turn him into a useful relief pitcher.  Speas turns 27 in March, so it isn’t too late for him to break out if he can deliver even a passable walk rate.

Mariners Sign Adonis Medina To Minor League Deal

By | at

The Mariners have signed right-hander Adonis Medina to a minor league deal, as reported by Matt Eddy of Baseball America. The deal presumably comes with an invite to big league Spring Training next year.

Medina, 28 next month, first signed with the Phillies out of the Dominican Republic and made his pro debut back in 2014. A starting pitching prospect at the time, Medina spent the early years of his career climbing the minor league ranks and was a consensus top-100 prospect in the sport after a strong showing at Single-A in 2017. The right-hander struggled a bit over the next two years, however, and his prospect star lost some of its shine as he struck out just 17.5% of opponents while allowing a 4.94 ERA at the Double-A level back in 2019.

Those struggles didn’t stop the Phillies from calling up Medina for his big league debut during the abbreviated 2020 season, however. In a spot start against the Blue Jays on September 20, Medina got his first cup of coffee in the big leagues. He performed solidly enough, surrendering two runs on three hits and three walks while striking out four in four innings of work, but was quickly optioned off the club’s roster. He remained with the Phillies for the 2021 season and performed well in the majors in a small sample while shuttling between the big leagues and Triple-A. Despite his 3.52 ERA in four appearances at the big league level, however, Medina struggled badly in the minors with a 5.05 ERA and a lackluster 18.4% strikeout rate at Triple-A.

Medina’s lackluster performance in the minors led the Phillies to place Medina on waivers, where he was promptly claimed by the Pirates only to be traded to the Mets the following month. The right-hander converted to relief full time in his new organization, and his results at the Triple-A level improved slightly (4.65 ERA in in 31 innings) after the role change. That step forward did not translate to the major leagues, however, as Medina was shelled to the tune of a 6.08 ERA in 23 2/3 innings of work across 14 appearances in Queens that year. While some peripheral numbers, such as his 3.89 SIERA, were more bullish on his performance, that wasn’t enough to keep Medina on the roster as the Mets designated him for assignment that September.

That led the right-hander to depart stateside ball for South Korea, where he signed with the KBO’s KIA Tigers. His new club tried to convert him back to starting, but that experiment did not go well as he struggled to a 6.05 ERA in 58 innings of work across 12 starts. Unlike his time in Queens, Medina’s struggles on the field were now reflected in his peripheral numbers as he struck out just 13.4% of batters faced while walking opponents at a 10.8% clip. Medina’s rough performance led to him being released that July, and he didn’t catch on with another club until he signed with the Nationals on a minor league deal in February of this year.

While Medina’s time with D.C. didn’t ultimately result in a return to the big leagues, he did show off the best results at Triple-A of his career after converting back to full-time relief with the Nationals. In 49 relief appearances, Medina posted a 3.76 ERA in 64 2/3 innings of work for the club’s affiliate in Rochester. He struck out a respectable 21.9% of opponents faced while walking 9.5%, the best ratio he’s flashed since his days as a top prospect in the late 2010’s. Now, Medina has latched on with a Mariners club that figures to give him the opportunity to earn a spot in the club’s bullpen out of Spring Training or act as non-roster depth in the minors should he ultimately not make the Opening Day roster.

Rangers Re-Sign Codi Heuer To Minor League Deal

By | at

The Rangers have re-signed right-hander Codi Heuer to a minor league deal, according to Matt Eddy of Baseball America. The deal presumably includes an invitation to big league Spring Training next year.

Heuer, 28, was a sixth-round pick by the White Sox back in 2018. The right-hander made it to the big leagues in fairly short order after being drafted, as he made his MLB debut during the shortened 2020 season. It was an impressive debut, as he pitched to an excellent 1.52 ERA in 23 2/3 innings of work in his first taste of big league action. He struck out 27.2% of opponents while walking 9.8% and posted a solid 2.77 FIP during the regular season, though he struggled in two postseason appearances against the A’s during the Wild Card series that October.

The youngster’s strong first impression was more than enough to earn him a spot with the White Sox headed into 2021, though he struggled early in the year. In 23 innings of work through June 4 of the year, Heuer posted a lackluster 6.26 ERA despite striking out a solid 25% of opponents and walking just 4%. Those strong peripherals left him with a solid 3.34 FIP despite his lackluster run prevention results, and the righty went on to post a much more characteristic 3.45 ERA over his next 18 appearances, which proved to be his final outings in a White Sox uniform. At the trade deadline, Heuer found himself traded across town to the Cubs alongside Nick Madrigal in exchange for closer Craig Kimbrel.

Results-wise, Heuer was impressive over the final two months of the season with the Cubs. He stepped into a late inning role with the club and collected two saves and four holds, posting a 3.14 ERA in 28 2/3 innings of work. Unfortunately, however, the peripheral numbers raised several red flags about the righty’s performance. His strikeout rate fell to just 14.8%, only slightly higher than his 11.3% walk rate during his time on the north side. Concerning as those warning signs were, however, the Cubs retained Heuer headed into the 2022 season with little to lose given they were just beginning to embark on a rebuild after dismantling their 2016 World Champion core of Anthony Rizzo, Kris Bryant, and Javier Baez.

Unfortunately, Heuer wouldn’t make it back to the mound in order to try and dispel any concerns that arose after his stretch run with the Cubs. He underwent Tommy John surgery in March of 2022, a procedure that left him away from the big league mound until midway through the 2023 season. Just when he was nearing a return to action, however, the right-hander underwent his second consecutive season-ending surgery in as many years when he suffered a fractured elbow. The right-hander eventually signed with the Rangers on a minor league deal after being non-tendered by the Cubs last November, and though he did not make it back to a pro mound in 2024, that they’ve now re-signed him seems to suggest they believe he could impact the club at some point in 2025.

Given the fact that he’s pitched just 12 2/3 innings over the past three years, it’s hard to know what to expect from Heuer once he finally makes it back to the mound. If he manages to shake off the rust of that long layoff, however, it’s not hard to imagine the right-hander proving to be a valuable piece of the bullpen puzzle next year for a Rangers club that had the fifth-worst bullpen in the majors by ERA last year despite standout performances from veterans David Robertson, Jose Leclerc, and Kirby Yates, all three of whom elected free agency earlier this month. That said, this reunion with Heuer won’t come close to moving the needle as much as is required for the Rangers to bolster their weakened bullpen, and they’re sure to look into more certain options for their relief corps as the winter continues.

Mariners Sign Yunior Marte To Minor League Deal

By | at

The Mariners have signed right-hander Yunior Marte to a minor league deal, according to a report from Francys Romero. Romero adds that the deal comes with an invite to MLB Spring Training.

Marte, 30 in February, signed with the Royals out of the Dominican Republic and made his pro debut back in 2013. He worked his way up the minor league ladder with Kansas City until he reached minor league free agency following the cancelled MiLB season in 2020, and eventually signed a minors pact with the Giants prior to the 2021 season. The right-hander spent two years in the Giants organization and pitched well at Triple-A despite the inflated offensive environment of the Pacific Coast League, prompting Marte’s promotion to San Francisco in April of 2022.

In the majors, Marte collected 48 innings with the Giants across 39 appearances. He posted a lackluster 5.44 ERA during that time, though his peripheral numbers (including a 4.38 FIP and 3.80 xERA) were solid enough. He struck out just 20.6% of opponents while walking 10.3%, but helped make up for that by generating poor contact, as evidenced by an impressive 48.6% groundball rate and a microscopic 3.5% barrel rate. That performance was solid enough to earn Marte a spot on the club’s 40-man roster throughout the offseason, but he nonetheless found himself traded to Philadelphia that January in exchange for southpaw Erik Miller.

Philly would serve as Marte’s home in each of the next two seasons, though his struggle to find results at the big league level continued. While Marte impressed with a 1.80 ERA in 20 Triple-A innings in 2023, his time in the majors told a different story as he surrendered a 5.03 ERA with a 4.68 FIP across 39 1/3 frames. While Marte’s strikeout, walk, and grounder rates all improved, opposing hitters began to find more success barrelling him up and that led to a spike in homers, which perhaps isn’t especially surprising given he moved from Oracle Park in San Francisco to the Phillies’ homer-happy home of Citizen Bank Park.

2024 turned out even worse for Marte, as the 29-year-old pitched to a 6.92 ERA with a 5.63 FIP while posting the worst strikeout rate, walk rate, groundball rate, and home run rate of his major league career. The disastrous results even carried over to Triple-A this season, as he surrendered a 6.88 ERA in 17 innings at the level. That led the Phillies to outright Marte off their roster earlier this month, and he subsequently elected free agency. The right-hander has now found a new home in Seattle, and he’ll have the opportunity to try and find his footing in an organization that boasts one of the best pitching staffs in the majors. That strong pitching staff could mean that Marte faces an uphill battle in trying to secure an Opening Day roster spot this spring, and barring him securing that roster spot he’ll likely open the season as non-roster depth for the Mariners in case of an injury.
