He left the LG Twins as one of the best closers in the KBO, bound for a big-league bullpen with the San Diego Padres. He returns to LG three years later with a very different job description. On September 1, LG announced it had signed right-hander Go Woo-suk and completed his player registration — bringing the 28-year-old back to the only Korean club he had ever pitched for, just three days after the Minnesota Twins designated him for assignment.
It is the kind of story that translates instantly, even for readers who have never watched a KBO game. A pitcher chases the majors, gets there, gets traded, gets cut — and comes home. What makes Go’s version notable is the shape of the arc: he did not wash out of affiliated ball or bounce around the minors for years. He posted for MLB rights as a proven closer, signed with a well-known National League franchise, got traded mid-season to a second team, and was let go by that second team in the span of about fourteen months. Now he is back in LG navy, wearing the same number he wore for seven seasons, with a specific and more modest role waiting for him in the bullpen.
The Announcement: One Year, Number 19
LG’s front office confirmed the deal on September 1, 2026. The contract is a one-year agreement worth a total of 500 million Korean won. Because Go is rejoining the club mid-season, with roughly three months of the schedule remaining, his actual payout for 2026 is prorated down to 150 million won for the balance of the year. The club also handled a smaller but symbolically loaded detail immediately: Go was reissued uniform number 19, the number he wore throughout his seven years with LG before he left for the United States.
Numbers like that do a lot of narrative work in Korean baseball, where fans track uniform numbers the way NBA fans track jersey retirements. Number 19 was Go’s number when he was LG’s closer of record, when he was closing out games in the KBO’s biggest ballparks, and when he represented Korea internationally. Getting it back, rather than being issued a new number as a returning player often is, was treated by outlets covering the signing as a small but pointed signal that LG was welcoming him back as himself, not as a reclamation project wearing a stranger’s digits.
Go addressed the move directly in LG’s official announcement. His comment was brief and functional rather than triumphant: he said he would “pitch for the team’s wins.” No grand statement about redemption, no direct reference to what happened in the U.S. — just a pitcher saying what he is there to do. In a league that tends to lean into narrative, the understatement is notable in itself.
How He Got to the Majors — and Why He Left
To understand why this return matters, it helps to rewind to how Go got to America in the first place. After the 2023 KBO season, Go went through the posting system — the mechanism South Korean clubs use to let a player negotiate with Major League teams while the KBO club receives a release fee. It’s the same system that has sent a long line of Korean players to MLB over the past two decades, and it is specifically why a KBO club can lose a player mid-contract without the player simply walking away as a free agent under U.S. rules. Posting is a negotiated exit, not a defection, and it usually happens because a player, his KBO club, and often the player’s camp all believe he is ready for a MLB roster spot.
Go was posted as one of the more established closers in the KBO at the time, and he landed with the San Diego Padres — a franchise recognizable to American sports fans well beyond the specifics of the transaction, thanks to stars like Fernando Tatis Jr. and Manny Machado anchoring the roster in recent seasons. For a KBO reliever, signing with a Padres bullpen was as high-profile a landing spot as the posting system typically produces.
What happened over the ensuing two-plus seasons in the Padres organization is not detailed in the confirmed reporting behind this story, and it would be irresponsible to guess. What is confirmed is the next hard transaction: this July, Go was traded from San Diego to the Minnesota Twins. Trades of this kind — a player moving from one MLB organization’s system to another mid-contract — are common enough in professional baseball, and on their own they don’t necessarily signal anything negative about a player’s standing. Rosters get reshuffled around trade deadlines for all sorts of organizational reasons that have nothing to do with the traded player’s performance.
But the next step in Go’s timeline is where the story turns. On August 29, the Minnesota Twins designated Go for assignment — a DFA. For readers unfamiliar with the mechanics: a DFA is not a release, but it starts the clock toward one. It means the team has taken the player off its 40-man roster and given itself a short window to trade him, place him on outright waivers (where any other team can claim him), or release him outright. It is one of the more unambiguous signals in professional baseball that a club, in the near term, does not see a role for a given player on its active roster. The specific baseball reasons behind Minnesota’s decision — performance, health, roster fit — are not established in the confirmed reporting on this story, and none should be assumed or implied here. What is established is the sequence of events: DFA on August 29, and an LG contract announced just three days later, on September 1.
From Closer to Long Man: LG’s New Plan for Go
Perhaps the most concrete piece of information in this story, for anyone trying to figure out what actually happens next, is what LG manager Yeom Kyung-yeop said about how he intends to use his returning pitcher. According to reporting from MoneyToday, Yeom laid out the bullpen picture plainly: incumbent closer Son Ju-yeong will continue closing games, while Go and Asia-quota pitcher John Kennedy will handle long relief innings out of the bullpen.
That is a meaningful demotion in job title from where Go left off in Korea. He was LG’s closer — the pitcher trusted with the ninth inning and the highest-leverage outs of the game — when he departed for the posting system after 2023. Long relief is a different job with a different rhythm: multiple-inning appearances, often in lower-leverage or unpredictable game situations, frequently used to save the rest of a bullpen after a starter exits early or a game gets out of hand. It’s a role built around innings and flexibility rather than the ninth-inning spotlight.
There is a version of this transition that reads as a step down, and there is a version that reads as a smart, low-risk reintegration plan for a pitcher who spent the last several weeks in the upheaval of a DFA and an international team change. LG did not need to hand Go the ninth inning to validate signing him; Son Ju-yeong has that job locked down, and installing Go directly into high-leverage save situations after a chaotic stretch would have been a bigger gamble than the club needed to take. Long relief lets LG get Go’s arm back into competitive innings, see where his stuff and health actually stand in September, and build toward whatever role makes sense from there — all without disrupting the ninth-inning role that is already working.
The Timing: A Mid-Season Reinforcement for a Playoff Push
Go isn’t walking into an offseason roster build — he’s walking into a team with roughly three months of regular-season games and a postseason push ahead of it. LG scheduled him to join the active roster on September 3, just two days after the signing was announced, which underlines how quickly the club wants him integrated into the bullpen mix rather than treated as a depth signing to be evaluated at leisure.
For a KBO club in playoff contention in September, adding a pitcher with genuine MLB-adjacent experience and a track record as a KBO closer — even in a long-relief role rather than a closing one — is the kind of depth move that can matter in October. Bullpens wear down over a long season, injuries and fatigue accumulate, and a fresh, high-pedigree arm capable of multiple competitive innings is a real asset heading into the stretch run, regardless of what specific inning he’s throwing.
Why the Posting System Makes This Different From a Typical DFA Story
In American baseball, a DFA is a routine transaction — dozens of players get designated for assignment every season, and most of the time it barely makes news outside the two clubs involved. What makes Go’s situation worth a second look is the posting system that got him to the majors in the first place, because it changes what “coming home” actually means for a player in his position.
When a KBO player is posted, his original Korean club receives a release fee from the MLB team that signs him, and the player himself signs a genuine MLB contract, subject to the same waiver rules, options, and roster mechanics as any domestically developed player. He is not on loan, and there is no guaranteed pathway back to his old KBO roster spot if things don’t work out in America — a posted player who gets cut has to actually re-sign with a KBO club as a free agent, the same way any player changing organizations would. That is exactly what happened here: LG had to sign Go to a new one-year contract, at a negotiated price, because his old contract with the club ended when he was posted after 2023. There was no automatic recall clause bringing him home; LG chose to bring him back, on new terms, because it saw a use for him in September.
That distinction matters for how readers should understand the 500-million-won deal. It isn’t a technicality or a formality — it’s a fresh contract negotiated from a position where Go had just been cut loose by an MLB club, for a player entering the final stretch of a KBO season already in progress. The prorated payout, the modest term length, and the bullpen role he’s stepping into all reflect a player and a club figuring out, in real time, what a mid-season reunion actually looks like.
A Familiar Story, Told in KBO Terms
American readers don’t need to know anything about the KBO, Jamsil Stadium, or Korean baseball’s ninth-inning culture to recognize the shape of this story. It is the same arc that plays out in American sports constantly: a player leaves home to chase the highest level of competition, gets a legitimate shot at a marquee organization, gets traded, gets cut loose, and has to decide what comes next. Some players in that spot fight for another shot in the same league. Go’s version of “what comes next” is going home — not to sit out the rest of the year, but to pitch immediately for a team fighting for a playoff spot, in whatever role that team needs.
There’s also a version of this story that resonates specifically because of who Go was before he left. He wasn’t a fringe prospect who got a look and didn’t stick — he was an established closer, good enough to be posted and signed by a Padres organization that had its pick of options on the international and posting markets. That’s what makes the DFA notable as a plot point, not as a verdict on his ability: a player who was trusted with the ninth inning in one league found himself, just over two years later, removed from a 40-man roster in another. Baseball’s hierarchy of trust — who closes, who sets up, who gets an inning in a blowout, who gets designated for assignment — resets constantly, and Go’s is resetting again, this time back on familiar ground.
What to Watch Next
The concrete facts of this story are locked in: the contract terms, the number, the DFA date, the trade timeline, and the stated bullpen plan from LG’s manager. What isn’t yet known — and what reporting has not established — is how Go will actually perform once he takes the mound for LG. His September 3 roster addition sets up an appearance sometime in the season’s final stretch, and how he looks in his first outings back in a LG uniform will say more about this move than any contract figure can.
For now, the story is simply this: a pitcher who left Korea as a closer, signed with a team many American fans recognize, got traded once, got designated for assignment once, and came home to a bullpen role built for innings rather than the spotlight — with a playoff race waiting for him three months from being decided. It is a smaller, quieter comeback than the one he probably pictured when he posted for MLB after the 2023 season. It is also, for a bullpen that needs arms in September, a genuinely useful one.
