Go Woo-suk, a Korean right-handed reliever for the Minnesota Twins’ Triple-A St. Paul Saints, was ejected on July 25 before his debut with the team after umpires discovered a foreign substance inside his glove during a mandatory pregame inspection. The 27-year-old was pulled from the mound in the seventh inning against Columbus without throwing a pitch, marking an unprecedented way to begin his minor league assignment after being demoted from MLB.

How the ejection unfolded

Go took the mound as the third pitcher in the top of the seventh inning at CHS Field in St. Paul with the Saints trailing 3-2. Before he threw a pitch, the umpire crew conducted a mandatory in-game inspection of his hands and glove under MLB rules introduced in 2021. One umpire discovered what appeared to be a foreign substance inside the glove, prompting all umpires to gather for a lengthy examination. The umpires then ejected Go and confiscated his glove. Local broadcasters called it the “wildest debut for a pitcher” and noted they had never witnessed such an incident.

Suspension and MLB comeback implications

If the violation is confirmed, Go faces a standard 10-game suspension under professional baseball’s foreign substance rules. The Minor League Baseball office had not yet announced disciplinary action as of July 26. The suspension poses a significant setback to Go’s bid to return to MLB after being demoted to Triple-A on July 25 following just four relief appearances with the Twins, where he posted a 9.00 ERA. Korean media outlet OSEN reported that the incident “raises the possibility of affecting his major league promotion plan.” Go’s path to rejoin his former Korean club LG Twins also appears blocked, as player registration procedures must be completed by month’s end and the foreign substance controversy remains unresolved.

Go’s troubled path to the majors

Go signed a two-year, $4.54 million contract with the San Diego Padres in January 2024 but never appeared in an MLB game before being traded to the Miami Marlins. After two seasons in the minors posting ERA figures of 6.54 and 5.10, he was acquired by the Twins this month. He made his MLB debut on July 8 and appeared in four games before being demoted. On July 21, Go was part of a Twins team that allowed seven home runs in a single game against Cleveland, the first time in 40 years the franchise had permitted that many in one contest. Patrick Bailey, a Cleveland batter, homered off Go twice in 11 days.

Controversy and fan reaction

Go’s use of a foreign substance contradicts his status as a pitcher seeking redemption after struggling in the majors. In 2023, while with the Angels, Go faced criticism for comments about Shohei Ohtani during the World Baseball Classic, stating he wanted to hit him “where it doesn’t hurt.” American fans responded harshly to the ejection, with social media users calling him a “fraud” and demanding the Twins release him outright. One commenter noted: “He seems to have known. He should be more careful going forward.”

Final Thoughts

Go’s ejection before his Triple-A debut marks a career-defining moment for the Korean reliever. With a 10-game suspension likely and his MLB comeback already stalled, Go faces an uncertain future in professional baseball.

FAQs

What foreign substance was found in Go Woo-suk’s glove?

The umpires did not specify the exact substance. Sticky materials like pine tar increase pitch spin rate and velocity when applied to a pitcher’s hand or ball.

How long is Go Woo-suk’s suspension?

If confirmed, the suspension is 10 games under Minor League Baseball’s foreign substance rules. The league had not yet announced final discipline as of July 26.

Why was Go demoted to Triple-A before the ejection?

Go appeared in four MLB games for the Twins with a 9.00 ERA before being sent down to Triple-A on July 25, one day before his ejection.

Can Go return to the Korean league instead?

Unlikely. Player registration with Korea’s LG Twins must be completed by July 31, and the foreign substance controversy remains unresolved, leaving insufficient time to clear it.
