KBO Reliever Woo Suk Go Requests To Be Posted For MLB Teams

By | at

TODAY: Go and his representatives have asked the Twins to post him for MLB teams this winter, according to reporter Daniel Kim and MyKBO.net’s Dan Kurtz.  (Both links via X.)  It isn’t yet known if the Twins will agree to Go’s request.

NOVEMBER 15: Major League Baseball has tendered a status check with the Korea Baseball Organization on LG Twins closer Woo Suk Go, reports Jee-ho Yoo of South Korea’s Yonhap News Agency. The status check is a formal procedure when big league clubs are showing interest in a player with the potential to be posted. Yoo writes that MLB has also tendered a status check on Kiwoom Heroes outfielder Jung Hoo Lee, for instance, although it’s been known for months now that Lee would be posted for MLB clubs, making the status check even more of a formality. Go, however, has not been the subject of potential posting rumors until now.

Go, 25, closed out the Twins’ victory in this year’s Korean Series — the team’s first KBO title in nearly three decades. He’s been the primary closer for the Twins for the past five seasons, pitching to a collective 2.39 ERA with 139 saves, a 30.2% strikeout rate, a 10% walk rate and a ground-ball rate north of 60% in that time. Go missed time this past season with a lower back injury but still pitched 44 innings of 3.68 ERA ball with a 31.1% strikeout rate, 11.6% walk rate and massive 65.8% grounder rate.

To be clear, tendering a status check is not a definitive declaration that the player will be making the jump to Major League Baseball. The Twins have yet to publicly indicate that they’ll post Go for big league clubs, apparent interest in him notwithstanding. Even if he is posted, there’s no guarantee he’ll ultimately sign in the Majors. For instance, star KBO outfielder Sung Bum Na was posted by the NC Dinos two seasons ago but ultimately returned to his former club after failing to reach an agreement. He played another season with the Dinos before becoming a free agent and signing a four-year, $12.6MM contract to remain in the KBO with a new team, the Kia Tigers.

That said, Go is still an interesting name to keep on the radar for MLB fans. Like Lee and Japanese ace Yoshinobu Yamamoto, he’s quite a bit younger than the majority of professional players from Asia who become available to big league clubs, having only turned 25 in early August. The 5’11”, 198-pound Go has a heater that sits mid-90s and was regularly in the 94-96 mph range during his recent Korean Series appearance. Prior to the season, Sports Info Solution’s Ted Baarda noted in his WBC preview that Go’s fastball has topped out at 98 mph. Dan Kurtz of MyKBO.net offered up some video of Go recording a save in Game 3 of the Korean Series earlier this month.

Because he has fewer than nine seasons of KBO service time, Go would need to enter Major League Baseball through the posting system. Upon being posted by the Twins, he’d have 30 days to agree to a contract with an MLB team. The team that signs Go would owe a posting/release fee to his former KBO club. That would be equal to 20% of the contract’s first $25MM, 17.5% of the next $25MM and 15% of any subsequent dollars committed to Go. (That’s on top of the money paid to Go himself — not subtracted from his guarantee.)

Interestingly, Go and Lee are brothers-in-law, though that holds little bearing beyond its sheer anecdotal nature. Perhaps the pair would prefer to land on the same team or at least in close proximity to one another if indeed both land in North American ball, though that’s purely speculative. And as always, the driving force behind the vast majority of free-agent signings is simply the strength of the offer in both years and dollars.

Despite his youth, Go has seven seasons of service time in the KBO, Yoo notes in his piece for Yonhap. Even if he doesn’t end up joining a big league team this offseason then, he’ll be on track to accrue the requisite nine years of KBO service time needed to qualify for unrestricted international free agency. That would allow him to field offers from MLB clubs in the 2025-26 offseason and make the jump to MLB without being subject to the posting system.

KBO’s Lotte Giants Re-Sign Aaron Wilkerson

By | at

The Lotte Giants of the Korea Baseball Organization announced Thursday that they’ve re-signed righty Aaron Wilkerson to a one-year deal for the 2024 season (English link via Jee-ho Yoo of the Yonhap News Agency). He’ll be guaranteed $750K and can take home another $200K of incentives.

Wilkerson, 34, logged big league time with the Brewers each season from 2017-19 but posted  a 6.88 ERA in a combined 35 1/3 innings. He’s since pitched in Triple-A with the A’s and Dodgers in addition to stints in Japan’s NPB and, in 2023, in the KBO.

His first year of KBO ball was a strong one. The 6’3″ righty joined the Giants midseason and made 13 starts with a sterling 2.26 ERA in 79 1/3 frames. Wilkerson fanned 24.8% of his opponents against a tidy 6.1% walk rate alongside a strong 56.1% grounder rate.

The journeyman righty, who’s pitched in four different MLB teams’ minor league systems in addition to stints in indie ball and in Asia, will now take home a nice seven-figure salary that can reach nearly $1MM — a nice windfall at this stage of an 11-year grind through professional ball.

Perhaps he can further parlay strong overseas results into an MLB return in his late 30s. Even if that’s not in the cards for Wilkerson, a nice 2024 campaign would likely put him in position to re-sign in the KBO and continue earning at levels he’s rarely, if ever seen to this point in his career.

Adam Plutko Eyeing MLB Return

By | at

Right-hander Adam Plutko is eyeing a return to the Major Leagues after a strong two-year stint in the Korea Baseball Organization, tweets Jon Heyman of the New York Post. The 32-year-old hurler landed with the 2023 KBO champion LG Twins after a largely nondescript five-year run between Cleveland and Baltimore and has found plenty of success pitching overseas.

In two seasons with the KBO’s Twins, Plutko has pitched to a 2.40 ERA in 285 1/3 innings. He’s still not a prolific strikeout arm, fanning just 21.7% of his opponents, but Plutko sports a sharp 6% walk rate and a solid 46% ground-ball rate during his time overseas. That’s a marked increase over his MLB numbers; from 2016-21 he logged 273 2/3 innings between the Indians and Orioles, recording a 5.39 ERA, 17% strikeout rate, 7.2% walk rate and 28.8% ground-ball rate — primarily working as a fifth/sixth starter with Cleveland.

Given his age, Plutko isn’t likely to command particularly long-term interest if MLB clubs are intrigued to roll the dice and see what he can bring to the table in a return affair. But he’s a year younger than Josh Lindblom was when he signed with the Brewers out of South Korea (three years, $9.125MM) and two years younger than Drew Rucinski was last year when he signed with the A’s following a successful KBO run of his own (one year, $3MM).

A low-cost deal for one or two years doesn’t seem out of the realm of possibility. Even if guaranteed rotation spots are tough to come by, Plutko could be targeted by clubs looking for an affordable swingman to serve as a sixth or seventh starter in the inevitable event that injuries thin out their more prominent rotation options. With 51 career relief outings in the Majors, Plutko is no stranger to being a long man in the bullpen.

Erick Fedde Drawing Interest From MLB Clubs

By | at

Right-hander Erick Fedde is drawing interest from major league clubs after spending 2023 with the NC Dinos of the Korea Baseball Organization, reports Jon Heyman of The New York Post.

Fedde, 31 in February, was once a highly-touted prospect, with the Nationals selecting him 18th overall in the 2014 draft. But he didn’t find much success in the big leagues, making 102 appearances for the Nats from 2017 to 2022 with a 5.41 earned run average.

As mentioned, he joined the Dinos for this past year and the move to Korea could hardly have gone better for him. He threw 180 1/3 innings over his 30 starts with his ERA finishing at an even 2.00. He struck out 29.5% of batters faced while walking just 4.9% and also kept the ball on the ground at an incredible 70% clip. For reference, the MLB ground ball rate was 42.5% in 2023. The overall results were strong enough for him to win the Choi Dong-won award, which is given to the best starting pitcher in the league each year, making it roughly the KBO equivalent of the Cy Young.

That figures to make Fedde an interesting wild card entry into the free agent pitching market this offseason, with MLBTR having given him an honorable mention in our recent Top 50 Free Agents post. The results for North American pitchers returning from a stint in Korea are mixed, with some recent examples ranging from Merrill Kelly to Chris Flexen to Josh Lindblom. Kelly has made 127 starts for the Diamondbacks over the past five years with a 3.80 ERA. Lindblom had great results in Korea but posted a 6.39 ERA in his 20 appearances for the Brewers. Flexen had a 3.66 ERA for the Mariners over 2021 and 2022 but was torched for an ERA of 6.86 in 2023.

Each pitcher is unique and precedent can only tell us so much about Fedde as an individual. Given his excellent 2023 campaign and status as a former top prospect, he should garner plenty of interest, particularly from the clubs priced out of the top of the market. Pitchers like Yoshinobu Yamamoto, Blake Snell, Aaron Nola and Jordan Montgomery seem positioned for nine-figure guarantees while sizeable eight-figure deals should be attainable by guys like Sonny Gray, Eduardo Rodriguez and Shota Imanaga.

Kelly got a two-year, $5.5MM deal from Arizona going into 2019. A year later, Lindblom got $9.125MM plus incentives over three years from the Brewers. Flexen got $4.75MM over two years from the Mariners prior to 2021, plus a vesting option for 2023. Fedde may be able to top those figures through a combination of his superb season, his former prospect pedigree and inflation, but the guarantee still figures to be lighter than the top available arms.

Latest On Jung Hoo Lee

By | at

KBO star Jung Hoo Lee has been one of the more intriguing potential free agents of the upcoming offseason ever since reports back in January indicated that he would be posted by his KBO club, the Kiwoom Heroes. A wrench was thrown in that plan when he recently required ankle surgery, though Jon Morosi of MLB.com reports today that Lee is still expected to sign with a major league club this winter.

Lee, 24, already has an impressive résumé in his short career. He won Rookie of the Year in the KBO in 2017 by hitting .324/.395/.417 when he was just 18 years old for most of the season. He continued to take steps forward in the years to come, especially in 2022. He launched 23 home runs and finished with a batting line of .349/.421/.575 for a wRC+ of 175. He struck out in 5.1% of his plate appearances while walking in 10.5% of them. He stole five bases and won a fifth straight Gold Glove, with all of those attributes leading to a Most Valuable Player award.

This year won’t be the perfect platform season for him, as he’s been a notch below that MVP form. His walk rate went up to 12.7% but he hit just six home runs, leading to a .319/.407/.456 batting line. His 142 wRC+ indicates he’s still been well above league average but not quite as outrageously as he was last year. To top things off, he’s now missing the final months of the season due to his aforementioned ankle surgery.

Perhaps he or the Heroes would have given some second thought to his posting, maybe delaying it by a year, though it seems the plan has yet to be altered. Morosi relays that neither party has given any indication that the path forward has changed.

Lee will turns 25 years old later this month and will no longer be considered an “amateur” by MLB rules and won’t be subject to the bonus pool system. He will therefore be free to sign a contract of any length or dollar amount, with the signing club also responsible for paying a posting fee to the Heroes. That’s tied to the size of the contract itself, with the MLB team owing the KBO club 20 percent of the contract’s first $25MM, 17.5 percent of the next $25MM and 15 percent of any dollars thereafter. That fee is on top of any dollars guaranteed to the player himself, and subsequent earning (e.g. performance incentives, contract options) are also subject to the posting system once they become guaranteed to the player.

This winter’s free agent class is headlined by starting pitchers, with very few impact bats expected to be available. Assuming Lee’s ankle heals up in the months to come and he is posted as expected, he figures to still draw plenty of interest.

KBO’s Samsung Lions To Sign Taylor Widener

By | at

The Samsung Lions of the Korea Baseball Organization have agreed to a deal with right-hander Taylor Widener, reports Jeeho Yoo of Yonhap News (Twitter link). Righty Albert Suarez is being released in a corresponding move.

Widener has spent the ’23 campaign in South Korea. The former Diamondback signed an offseason deal with the NC Dinos. He started 11 games, working to a 4.52 ERA over 61 2/3 frames. Widener had a decent 22% strikeout rate against a slightly elevated 8.9% walk percentage.

While his production was serviceable, it wasn’t enough for the Dinos to commit one of their two allotted roster spots to foreign-born pitchers. They released him last week and signed left-hander Tanner Tully out of the Yankees’ organization. According to Yoo, Widener’s contract will be made official on Friday, as KBO rules require a player to wait a week upon being waived before signing with another team.

It’s not common to see foreign players immediately catch on with a different KBO team after being released. Widener is healthy, though, so the Lions will swap him in for Suarez. The Venezuelan-born hurler (and older brother of Padres reliever Robert Suarez) recently suffered a calf injury and is expected to be out around a month, tweets Dan Kurtz of MyKBO.

Suarez, a 33-year-old righty who pitched in the majors with the Giants from 2016-17, spent a year and a half with the Lions. He had an excellent 2.49 ERA showing through 173 2/3 innings a season ago and carried a 3.92 ERA over 19 starts this year. Unfortunately, the injury cut that productive run short.

Tanner Tully Signs With KBO’s NC Dinos

By | at

The Yankees announced they’ve granted minor league southpaw Tanner Tully his release to pursue a contract with the NC Dinos of the Korea Baseball Organization. According to Jeeho Yoo of Yonhap News, he’ll be paid $200K for the stretch run. The Dinos released right-hander Taylor Widener in a corresponding move.

Tully, whose MLB experience consists of three relief outings for the 2022 Guardians, never cracked the big league roster in the Bronx. He signed a minor league deal over the winter and has spent the season with Triple-A Scranton/Wilkes-Barre. The Ohio State product started all 19 appearances there. His 5.64 ERA through 91 innings isn’t eye-catching, though it’s at least partially inflated by a lofty .365 average on balls in play.

The 28-year-old has kept his walks to a tidy 6.3% clip for the RailRiders. His 18.6% strikeout rate is a few percentage points below average. Tully has had a pitch-to-contact approach throughout his career. Over seven seasons in the minors, he has a 17.4% strikeout rate and 4.8% walk percentage.

Widener heads back to the free agent market and could find minor league interest in the U.S. He made 49 appearances (13 starts) with the Diamondbacks between 2020-22, working to a 4.26 ERA across 107 2/3 innings. He moved to Korea after being waived off Arizona’s roster in January. Widener’s lone season with the Dinos consisted of 11 starts with a 4.52 ERA. He fanned 22% of KBO opponents against an 8.9% walk rate.

Lee Jung-hoo To Require Season-Ending Ankle Surgery

By | at

Outfielder Lee Jung-hoo of the Kiwoom Heroes in the KBO League will miss the next three months due to an ankle injury that requires surgery, reports Jeeho Yoo of Yonhap News Agency. There’s less than two months remaining in the KBO regular season schedule, meaning this will effectively end his season.

Lee, 24, has already established himself as one of the better players in the KBO League despite his young age. He won Rookie of the Year in 2017 after hitting .324/.395/.417 when he was just 18 years old for much of the year. He continued to improve his game in subsequent seasons, including last year. He hit 23 home runs and produced a batting line of .349/.421/.575 for a wRC+ of 175. He struck out in just 5.1% of his plate appearances while walking in 10.5% of them. He also stole five bases and won a Gold Glove for a fifth straight year, with his combined efforts leading to a Most Valuable Player award.

He was surely hoping for another strong season here in 2023, since the Heroes announced in January that he will be posted for major league clubs afterwards, allowing him to attempt to make the move to North America at the age of 25. But it’s not going to end up playing out in ideal fashion for Lee. In 85 games this year, he still played well, but at a level below his MVP campaign last year. His walk rate ticked up to 12.7% but he hit just six home runs, leading to a .319/.407/.456 batting line. His 142 wRC+ indicates he’s still been way above average but not quite as outrageously as last year.

On top of that relatively diminished output, he’ll now have to miss the final few months of the season and will likely go into the winter with uncertainty surrounding his health status. It’s obviously an ill-timed development for Lee, who was surely hoping to earn a significant contract in making the jump to Major League Baseball. Since he turns 25 in August, he will no longer be considered an “amateur” by MLB rules and won’t be subject to the bonus pool system.

He will therefore be free to sign a contract of any length or dollar amount, with the signing club also responsible for paying a posting fee to the Heroes. That’s tied to the size of the contract itself, with the MLB team owing the KBO club 20 percent of the contract’s first $25MM, 17.5 percent of the next $25MM and 15 percent of any dollars thereafter. That fee is on top of any dollars guaranteed to the player himself, and subsequent earning (e.g. performance incentives, contract options) are also subject to the posting system once they become guaranteed to the player.

Lee seemed to be set up to be one of the more intriguing free agents this winter, especially since the class seems heavy on pitchers and light on position players. That might still be the case, though it’s possible that this injury situation has an impact on things, depending on how he progresses between now and the winter.

KBO’s Lotte Giants Sign Aaron Wilkerson, Release Dan Straily

By | at

The Lotte Giants of the Korea Baseball Organization announced an agreement with right-hander Aaron Wilkerson this morning (h/t to Jeeho Yoo of Yonhap News). He’ll be paid $350K through season’s end.

Wilkerson, 34, has pitched professionally since 2013. He logged 14 big league appearances, all of which came with Milwaukee between 2017-19. Wilkerson spent part of last season in Japan with the Hanshin Tigers before returning to the U.S. for 2023. He’d been in the A’s system on a minor league pact, working to a 6.51 ERA through 47 innings with Triple-A Las Vegas.

The A’s granted Wilkerson his release last week. That was apparently so he could pursue the KBO opportunity, which’ll be the first of his career. (Oakland subsequently signed righty Zack Godley as non-roster rotation depth). Wilkerson has a 4.02 ERA over parts of five Triple-A seasons, striking out just under a quarter of opponents in the process.

In a corresponding transaction, Lotte released veteran righty Dan Straily. KBO teams are permitted a maximum of three foreign-born players (two pitchers) on the roster. The Giants will move forward with Charlie Barnes and Wilkerson. Straily has spent four of the last five seasons with Lotte. He was effective for the bulk of that time, including a 2.50 ERA in 2019 and a 2.31 mark over 11 starts after re-signing last August.

Straily hasn’t quite found his groove in 2023, however. He has a 4.37 ERA with a 19.2% strikeout rate and elevated 10.2% walk percentage through 80 1/3 innings. That led the Giants to move on and put Straily back on the open market. The 34-year-old was in affiliated ball last season, spending some time with the Diamondbacks’ Triple-A club. He hasn’t pitched in the majors since an eight-year run from 2012-19.

KBO’s Kiwoom Heroes Sign Ronnie Dawson

By | at

The Kiwoom Heroes of the Korea Baseball Organization announced yesterday they’ve signed outfielder Ronnie Dawson to a contract for the remainder of the 2023 season (h/t to Jeeho Yoo of Yonhap News). He’ll be paid an $85K salary through year’s end. In a corresponding transaction, the Heroes released infielder Addison Russell.

Dawson, 28, got cups of coffee at the MLB level in 2021-22. The Ohio State product debuted with three games for the Astros — the club that originally selected him in the second round of the 2016 draft — late in the ’21 season. He returned to the majors for a one-game stint with the Reds last year while the team was dealing with COVID-19 issues.

The left-handed hitter spent the rest of last season with the Reds’ top minor league club in Louisville. He hit .252/.339/.394 with 11 homers and stolen bases apiece. He’d been playing in the independent ranks this year. Dawson was off to a .282/.363/.512 start with 13 longballs in 64 games for the Atlantic League’s Lexington Counter Clocks.

Making the jump to the KBO surely comes with a nice pay bump. If he hits well in this audition, he could play his way into another deal there or in Japan’s Nippon Professional Baseball for 2024. Dawson has scant MLB experience but might put himself back on the big league radar with a strong KBO showing, particularly if he does spend multiple seasons there.

Russell returns to free agency after hitting .286/.339/.400 in 59 games. Yoo notes that he hasn’t played in nearly a month because of a wrist injury. KBO teams are limited to three foreign-born players on the roster, so they typically have a short leash when one of those players is hurt for a notable stretch of time. The former Cub shortstop hasn’t played in the majors since 2019 after serving a 40-game domestic violence suspension the year prior.
