Daniel Castano Announces Retirement

By | at

Left-handed pitcher Daniel Castano announced his retirement via a post on his personal Instagram account. “After 25 Baseball seasons, 9 years pro, 3 in college, 4 in HS, and 10 years of little league, I’m finally hanging up the cleats and for my more important career in life,” the post reads. “To be a loving Husband, father, friend, churchman and employee.” He goes on to thank the many people who helped him on his journey and mentions he will be pivoting to a role with Entrusted Contracting.

As Castano himself mentioned, his baseball journey had many stops. He pitched at Lake Travis High School in Austin, Texas, which then led him to Baylor University. He pitched three seasons for the Bears before the Cardinals selected him in the 19th round of the 2016 draft.

Just over a year later, Castano was flipped to the Marlins. Zac Gallen, Sandy Alcántara, Magneuris Sierra and Castano were sent to Miami in the December 2017 trade that sent Marcell Ozuna to St. Louis. Castano made it to the big leagues with the Fish in 2020, the first of four straight major league campaigns in which he appeared. He logged 88 2/3 frames over those four seasons, allowing 4.47 earned runs per nine. His 12.4% strikeout rate wasn’t especially strong but he limited walks to a 7.9% clip and kept 45.2% of balls in play on the ground.

The Marlins shuffled Castano on and off their roster in 2023 but he wasn’t holding a 40-man spot at the end of the season and became a free agent. In December, he landed a deal with the NC Dinos of the Korea Baseball Organization. He made 19 starts for the Dinos this year, posting a 4.35 ERA in 111 2/3 innings. At the end of July, the Dinos signed Eric Jokisch and bumped off Castano, as a KBO team can only have two non-Korean pitchers on its roster.

Now it seems Castano has decided it’s time to move on from baseball and move towards, as he puts it, his “more important career in life.” We at MLBTR salute him on carving out a big league career and we wish him the best for the upcoming chapters of his life.

Darin Ruf Joins University Of Nebraska Omaha Coaching Staff

By | at

Former big league first baseman/outfielder Darin Ruf has joined the University of Nebraska Omaha baseball program as an assistant coach, the school announced Wednesday. There’s been no formal announcement of retirement for the 38-year-old Ruf, but this certainly seems to indicate he’s turning the page on his playing days and moving onto the next phase of his baseball journey.

“We are thrilled to have Darin join our baseball family,” Mavericks head coach Evan Porter said in a statement within today’s announcement. “Darin’s incredible track record speaks for itself, but his character and work ethic are perhaps more impressive. I’ve been fortunate to know Darin for the past 20 years, his respect for the game and for the people around him is admirable. I couldn’t be more excited to work with Darin, he is a tremendous addition to our program.”

A 20th-round pick out of Omaha’s Creighton University back in 2009, Ruf reached the majors with the Phillies in 2012 and went on to enjoy a nine-year career in the major leagues in addition to an excellent three-year run with the Samsung Lions of the Korea Baseball Organization (2017-19).

Ruf’s debut campaign with the Phils was brief but showed clear potential for a meaningful big league career. He appeared in 12 games as a September call-up and popped three homers while batting .333/.351/.727 in 37 trips to the plate. The following season saw Ruf tally 293 plate appearances while hitting .247/.348/.458 with 14 round-trippers. He’d ultimately spend parts of five seasons with the Phillies, from 2012-16, batting a combined .240/.314/.433 while serving as a part-time first baseman and corner outfielder who could provide some right-handed thump off the bench.

From there, Ruf’s next stop was overseas. He not only found success with the KBO’s Lions — he took the entire league by storm. Ruf smacked 38 homers in his first Korean season and wound up posting a massive .313/.404/.564 batting line in 1756 plate appearances as a Lion. He belted 86 homers, 105 doubles and six triples during his run in the KBO, with overall offense about 45% better than league-average, by measure of wRC+.

Ruf returned stateside for the 2020 season, taking a minor league deal with the Giants that proved to be an outstanding deal for San Francisco. He cracked the Giants’ opening day roster in the shortened 2020 campaign, his age-33 season, and in 100 plate appearances turned in a .276/.370./517 slash that made him an easy call to keep for the Giants to tender him a contract in arbitration in the 2020-21 offseason. Ruf’s 2021 output was even better than that small-sample 2020 showing; in 312 plate appearances he hit .271/.385/.519 with 16 homers.

That sudden resurgence in the majors prompted the Giants to ink Ruf to a two-year, $6.25MM contract. His bat took a step back in the first season of the deal, but Ruf was still hitting at a slightly better-than-average level when the Mets acquired him at that summer’s trade deadline. His bat cratered following the move to Queens, however, and New York designated Ruf for assignment just before Opening Day 2023. He was released in early April, signed a minor league deal to return to the Giants, and split the 2023 season between San Francisco and Milwaukee, seeing brief playing time at both stops.

It now seems likely that’ll be the final stage of Ruf’s playing career. If he’s indeed shifting his focus to a coaching track, he’ll conclude his time in the majors with a career .239/.329/.427 batting line, 351 hits, 67 homers, 69 doubles, three triples, six steals, 198 runs scored and 205 runs driven in. Between MLB and the KBO, he cracked more than 150 homers and piled up more than 800 hits — all while earning more than $9MM in the majors and more than $4MM in South Korea.

The Omaha native will now help mold a younger generation of players while returning to his hometown. Ruf expressed excitement and gratitude in a statement of his own within today’s announcement:

“I am thrilled to be joining Evan’s staff in Omaha. I have been blessed with amazing coaches throughout my career and I am honored Evan has given me the opportunity to give back and work with these student athletes. I look forward to working with them on the field to become the best ball players they can be and off the field as they continue to develop into great people for the community of Omaha.”

KBO’s Kia Tigers Sign Eric Stout

By | at

The Kia Tigers of the Korea Baseball Organization announced this week that they’ve signed former MLB left-hander Eric Stout. He’s a temporary injury replacement for righty James Naile, who sustained a broken jaw when he was hit in the face by a comebacker off the bat of Matt Davidson (link via Jeeho Yoo of Yonhap News).

Stout, a 31-year-old southpaw, has 23 major league appearances under his belt. Three of them came with the Royals in 2018. The remainder were in ’22, when he combined for 20 outings between the Pirates and Cubs. Stout turned in a 5.64 ERA across 22 1/3 innings, striking out 22.7% of batters faced against an elevated 14.5% walk rate. He spent most of last year in Triple-A and signed in Taiwan’s Chinese Professional Baseball League for the ’24 season. Stout had a 2.77 ERA across 113 2/3 innings spanning 20 appearances to earn the bump to the KBO.

Naile, 31, appeared in 17 games for the Cardinals between 2022-23. While he struggled to a 7.40 earned run average, he parlayed a strong Triple-A season into a deal with the Kia Tigers. The UAB product had a 2.53 ERA with a decent 21.5% strikeout rate over 149 1/3 frames in his debut year in Korea. The jaw injury unfortunately ends his regular season, though Yoo suggests he could return in the playoffs.

KBO’s Samsung Lions Sign Lewin Diaz

By | at

The Samsung Lions of the Korea Baseball Organization announced this week that they’ve signed first baseman Lewin Díaz (relayed on X by Dan Kurtz of MyKBO). The CAA Sports client receives a $50K salary with up to $20K in incentives for the stretch run. The Lions also paid a $100K release fee to the Diablos Rojos del Mexico, the Mexican League team with which Díaz had been playing. Samsung waived outfielder Ruben Cardenas in a corresponding move.

Díaz, 27, was an MLBTR staple during the 2022-23 offseason. He changed teams via waivers or minor trade four times that winter. The Orioles eventually succeeded in sneaking him through waivers and kept him in Triple-A for all of last season. Díaz had a decent year in the minors, hitting .268/.362/.442, but never got an MLB look from Baltimore. He qualified for minor league free agency over the winter and signed a non-roster deal with the Nationals.

Washington released Díaz at the end of camp. He didn’t land another affiliated deal, instead making the move to Mexico. The left-handed hitter has mashed at a .376/.452/.647 clip with 19 homers across 75 games in that very hitter-friendly league.

Díaz was a fairly well-regarded prospect with the Twins early in his pro career. Minnesota dealt him to the Marlins as part of a deal for reliever Sergio Romo in 2019. Díaz didn’t hit major league pitching over parts of three seasons in Miami, running a .181/.227/.340 slash in 112 games. He has been an above-average Triple-A batter, posting a .258/.341/.479 mark in nearly 1200 plate appearances at the level.

Astros’ Eric Lauer Granted Release, Will Reportedly Pursue KBO Opportunity

By | at

The Astros released left-hander Eric Lauer, who’d been with their Triple-A club in Sugar Land, per the transaction log at MiLB.com. It seems that’ll pave the way for the former Brewers and Padres hurler to sign in the Korea Baseball Organization. Per KBO reporter Daniel Kim, Lauer will sign a deal with the Kia Tigers for the remainder of the 2024 campaign.

Lauer, 29, opened the season with the Pirates’ Triple-A affiliate after signing a minor league deal in spring training and joined Houston’s Triple-A club a couple months later after opting out of that deal with Pittsburgh. He’s had rough results on the whole in Triple-A this season, working to a combined 5.26 ERA between the two teams. However, he’s been on a good run as of late (2.86 ERA over his past five starts), has maintained respectable strikeout/walk rates throughout the ’24 season (25.3%, 9.1%), and of course has a big league track record of some note.

Selected by the Padres with the No. 25 overall pick in the 2016 draft, Lauer made his big league debut with San Diego in 2018 and spent two seasons pitching at the back of the Friars’ rotation. He logged a 4.40 ERA over 53 appearances (all but one of them as a starter) and looked well on his way to cementing himself as a serviceable back-end option. The Padres traded him to Milwaukee alongside Luis Urias in a trade shipping Trent Grisham and Zach Davies back to San Diego. Lauer made four ugly appearances during the pandemic-shortened 2020 season, yielding 16 runs in 11 innings, but bounced back in a major way the following year.

Early in the 2021 season, Lauer added a slider to his repertoire and saw his results take off. He posted a 3.19 ERA and fanned 24% of his opponents in 118 2/3 innings that year, including a minuscule 2.41 ERA after incorporating his new breaking ball. The strong results continued into 2022, and Lauer wound up pitching to a combined 3.47 ERA in 277 1/3 frames across the two seasons, fanning 23.8% of his opponents against an 8.7% walk rate.

Lauer’s 2022 season was slowed by a shoulder issue, however, and he battled shoulder and elbow troubles the following year as well. The lefty saw his average fastball plummet from 93.3 mph in 2022 to 91.2 mph in 2023. In 46 2/3 big league frames, he was tattooed for a 6.56 ERA as his K/BB rates both went in the wrong direction. The Brewers sent him to Triple-A Nashville to try to get him right, but Lauer’s struggles continued, as he was knocked around for a 5.15 ERA there and did not return to the big leagues.

Lauer clearly hasn’t recaptured his 2021-22 form in Triple-A this season, but he’ll aim to do so down the stretch in the KBO with a Kia club that’s currently sporting the league’s best record at 60-41. It’s feasible that a big showing overseas could lead to interest from MLB clubs this winter, but it could also open the door for Lauer to re-sign with the Tigers for the 2025 campaign. He’d pitch all of next season at 30 years of age, and if he can either rebound to 2021-22 form or reinvent himself with some new offerings (a la Erick Fedde), an additional year in the KBO could catapult him back onto the big league radar.

KBO’s NC Dinos Sign Eric Jokisch, Release Daniel Castano

By | at

The NC Dinos of the Korea Baseball Organization announced yesterday that they’ve signed left-hander Eric Jokisch to a $100K deal for the rest of the season. The news was relayed (on X) by Dan Kurtz of MyKBO, who tweeted earlier this week that the Dinos were waiving southpaw Daniel Castano to facilitate a deal for another foreign player.

KBO teams can have a maximum of two non-Korean pitchers on their roster. The Dinos signed former Red Sox left-hander Kyle Hart over the offseason. He’s having a very nice season, working to a 2.47 ERA through 124 innings. Castano had a more pedestrian 4.35 mark in 111 2/3 frames. He struck out 18.7% of opponents against a tidy 5.3% walk percentage.

Castano is a former 19th round pick by the Cardinals who went to the Marlins in the Marcell Ozuna/Sandy Alcantara/Zac Gallen trade. He’d go on to make 24 appearances over parts of four seasons in Miami, working mostly as a depth starter. Castano turned in a 4.47 ERA in 88 2/3 big league innings. He made the jump to Korea last offseason, not long after being waived by Miami in September.

Jokisch is also a former big leaguer, though he’s been far more established in Korea. His major league work consists of four appearances for the Cubs a decade ago. The Northwestern product subsequently kicked off a very successful KBO run in which he turned in a 2.85 earned run average over five seasons as a member of the Kiwoom Heroes. His tenure with the Heroes came to an unfortunate end last summer when he suffered a muscle tear in his leg that led the team to release him. (Injured players would still count against a KBO team’s foreign player limit.) The 35-year-old gets a new opportunity to resume his career.

In one other bit of KBO news — or more accurately, lack thereof — reporter Daniel Kim tweets that July 31 was the Korean league’s trade deadline. There were zero trades made.

KBO’s Doosan Bears Sign Jared Young

By | at

The Doosan Bears of the Korea Baseball Organization announced they’ve signed utilityman Jared Young (h/t to Jeeho Yoo of Yonhap News). The Old Dominion product had been playing in Triple-A with the Cardinals.

Young was a 15th round pick by the Cubs back in 2017. He reached the majors late in the 2022 season and appeared in 22 games over the next two years. The left-handed hitter ran a .210/.290/.435 line with a pair of home runs across 69 trips to the plate. Chicago placed Young on waivers at the start of last offseason. St. Louis nabbed him from their rival and successfully passed him through waivers during Spring Training.

Assigned to their top farm team in Memphis, Young was hitting .285/.411/.506. He connected on 11 homers and walked at a strong 14.3% clip against an 18.5% strikeout rate. The Cards never called him up, but his excellent work in the upper minors gets him a look in the KBO. That surely comes with a nice pay bump compared to his Triple-A salary.

KBO teams are only permitted to roster three foreign-born players. As a corresponding move for signing Young, they waived outfielder Henry Ramos. The 32-year-old signed with the Bears over the winter. He was hitting .306/.360/.482 in 80 games. That’s strong production, but Yoo notes (on X) that the Bears’ coaching staff has taken issue with Ramos’ defense and baserunning. A veteran of 12 minor league seasons, Ramos has logged brief MLB time with the Diamondbacks and Reds.

Elieser Hernández Signs With KBO’s LG Twins

By | at

The LG Twins of the Korea Baseball Organization announced that they have signed right-hander Elieser Hernández, as relayed on X by Dan Kurtz of MyKBO.net. The righty will make an annual salary of $440K. KBO clubs are only allowed to roster two foreign-born pitchers, so the Twins have put righty Casey Kelly on waivers to make room for Hernández.

Hernández, 29, once looked like he was emerging as a viable rotation candidate with the Marlins but has endured his share of struggles in recent years. He started 17 times for the Fish over 2020 and 2021, logging 77 1/3 innings with a 3.84 earned run average. He struck out 26.3% of batters faced in that time and limited walks to a 5.7% clip.

Unfortunately, he hasn’t been near that kind of form since then. He struggled in 2022, getting bumped to the bullpen and also to the minors at times, finishing the year with a 6.35 ERA at the major league level. He was traded to the Mets going into the 2023 season but that ended up being a lost year for him as a shoulder strain prevented him from pitching in the majors and limited him to just 9 1/3 minor league frames pitched on a rehab assignment.

Here in 2024, he spent some time with the Dodgers and Brewers. He has a 6.32 ERA in 15 2/3 innings at the major league level and a 2.83 ERA in 28 2/3 innings in Triple-A. He recently elected free agency after being designated for assignment by Milwaukee and will now look for a rebound overseas.

Plenty of pitchers have been able to reinvent themselves in the KBO and have then come back to Major League Baseball, including Josh Lindblom, Merrill Kelly and Chris Flexen. The most recent success story is Erick Fedde, who won MVP in the KBO last year and parlayed that into a two-year deal with the White Sox. He’ll make $15MM on that pact and seems likely to be traded to a contender since he has a 2.99 ERA through 19 starts this year. That would be an absolute best-case scenario for Hernández but there’s plenty of precedent for guys going down this road and doing well for themselves.

As for Kelly, 34, he pitched for a few MLB clubs last decade but has been with the LG Twins since 2019. He has a 3.25 ERA in almost 1,000 innings for that club but his ERA has jumped to 4.51 this year. He was striking out 23% of batters faced in 2022 but that number dropped to 17.3% last year and is down to 13.9% in 2024.

Jordan Balazovic Signs With KBO’s Doosan Bears

By | at

Right-hander Jordan Balazovic has signed with the Doosan Bears of the Korea Baseball Organization, according to Jeeho Yoo of Yonhap News. Balazovic had previously been pitching for the Twins on a minor league deal he signed back in February.

Balazovic, 25, was selected by Minnesota in the fifth round of the 2016 draft and has spent his entire professional career with Minnesota to this point. The right-hander posted big numbers in the lower minors early in his career, including a 2.69 ERA with a 33.9% strikeout rate in 93 2/3 innings of work split between the Single-A and High-A levels back in 2019. That was enough to get the Ontario native some attention on top-100 prospect lists, and his respectable 3.62 ERA in 20 starts as a 22-year-old at the Double-A level did little to dissuade that.

Unfortunately, the wheels came off from Balazovic a bit from there. Since being promoted to the Triple-A level to open the 2022 campaign, the righty has struggled mightily at the level with a 6.35 ERA with an 11.5% walk rate against a 25% strikeout rate in 68 appearances at the level. A difficult 2022 season saw the youngster move to the bullpen in 2023 and, while he made his big league debut with the Twins last year and posted a 4.44 ERA in 24 1/3 innings of work, that didn’t help him with his control as he walked 15.2% of batters faced in Triple-A last year. Those struggles led the Twins to designate him for assignment this past winter, though he re-upped with Minnesota on that aforementioned minor league pact and returned to Triple-A with the club to start the season.

Balazovic’s results have once again left something to be desired as he’s posted a 5.60 ERA in 35 1/3 innings of work this season. Those numbers hide the fact that Balazovic has looked greatly improved in terms of underlying performance, however. He’s struck out 30.1% of batters faced this year, the first time he’s punched out 30% of more of his opponents in half a decade. He’s paired that with an elevated but manageable 9.2% walk rate, and he’s even posted an impressive 56.2% groundball rate. That’s left him with strong peripherals, including a 3.21 FIP and 3.18 xFIP, but his results have been skewed by an elevated .368 BABIP allowed and a shockingly low 58.2% strand rate.

Doosan has clearly looked past Balazovic’s shaky results and is hoping that those strong peripherals in Triple-A this year can translate to success overseas. The right-hander now figures to head to Korea in hopes of finding success there and, perhaps, eventually establishing himself enough to get another crack at the big leagues at some point in the future. KBO teams are only allowed to carry a maximum of two foreign-born pitchers on their rosters, and to make room for Balazovic on the roster Yoo notes that the club parted ways with right-hander Raul Alcantara. Alcantara, 31, pitched for the A’s in the majors in 2016 and ’17 and posted a 4.76 ERA in 12 starts with Doosan this year.

KBO Infielder Hyeseong Kim Hires CAA Ahead Of Expected Posting For MLB Teams

By | at

Infielder Hyeseong Kim, who stars for the Korea Baseball Organization’s Kiwoom Heroes, has hired CAA Baseball to represent him ahead of his expected move to Major League Baseball in the upcoming offseason, reports Jeeho Yoo of South Korea’s Yonhap News Agency. (Kim’s name is commonly written as Kim Hye-Seong or Hye-Seong Kim, but Yoo further notes via X that CAA specifically informed him the infielder will go by Hyeseong Kim if he indeed moves to North American ball.)

Kim, who’ll turn 26 next January, is old enough and has enough experience in a major foreign league to be considered a “professional” under Major League Baseball’s international standards. He’ll be exempt from international amateur free-agent bonus pools and thus able to sign a major league contract for any length and dollar amount with an interested team.

The former double-play partner of current Padres infielder Ha-Seong Kim, the younger Kim is  a lifetime .301/.361/.398 hitter in 876 games with the KBO’s Heroes. One of the primary knocks on his MLB outlook throughout his pro career has been a lack of power, but he’s begun to change that narrative in his age-25 campaign. The lefty-swinging Kim has appeared in 50 games and taken 224 plate appearances this year but has already set a new career-high with eight home runs. (He’d previously hit seven homers in two different seasons, including 2023.) Overall, Kim is slashing .309/.366/.471 this season — his fourth consecutive season with a .300 or better average.

Kim has also picked up seven doubles and a triple this season in addition to going 15-for-16 in stolen bases. The 6.7% walk rate Kim has posted so far in 2024 is a career-low — perhaps a sign of a more aggressive approach as he tries to showcase for MLB teams, speculatively speaking — but his minuscule 9.8% strikeout rate is also the lowest of his career. Kim has dropped his strikeout rate in every season of his pro career, beginning with a 25.2% mark back in 2018. He’s now seen as a hitter with plus contact skills, well above-average speed — he’s 195-for-226 (86.3%) in career stolen base attempts — and a strong glove in the middle infield.

Prior to the 2023 World Baseball Classic, Baseball America’s Kyle Glaser ranked Kim ninth among the top-ten MLB prospects for fans to track (landing behind current big leaguers Yoshinobu Yamamoto, Jung Hoo Lee and Yariel Rodriguez). Glaser called Kim a plus defender at second base (and a capable defender at short) with a “preternatural feel for contact,” good pitch recognition and the ability to catch up to good velocity. At the very least, he could profile as a utilityman with high-end speed and contact skills, though it should come as little surprise if there are clubs who view him as a potential regular at second base. Given his age, Kim should find big league interest — particularly if he can continue his newfound power output.

CAA most famously represents Dodgers star Shohei Ohtani but is also one of the industry’s largest firms, representing dozens of clients, including high-profile names like Willy Adames, Sandy Alcantara, Corbin Carroll, Jack Flaherty, Max Fried, Lucas Giolito, Jon Gray, Josh Hader, J.T. Realmuto and Trea Turner — among many others (as can be seen in MLBTR’s Agency Database).
