Seung-hwan Oh

A product of the KBO, right-hander Seunghwan Oh spent nine seasons with the Samsung Lions before signing with the Hanshin Tigers of the Nippon Professional Baseball league for the 2014 and 2015 seasons. Oh made the move to the MLB during the 2015/2016 offseason, signing a one-year deal with an option for the 2017 campaign with the St. Louis Cardinals.

Following the 2017 season, Oh joined the Blue Jays on a one-year $2 million deal that included an option for the 2019 campaign. With the Jays, Oh posted a 2.68 ERA through 48 appearances with two saves and a 10.5 K/9. The front office ended up trading the reliever to the Colorado Rockies at the deadline in exchange for prospects Forrest Wall, Chad Spanberger, and a player to be named later (which ended up being new enemy Bryan Baker).

The Rockies released the South Korea product during the 2019 season after it was announced he would miss the remainder of the season with an elbow injury. Oh returned to the KBO and signed with the Samsung Lions for the remainder of the year. He was unable to pitch due to the injury and also because of disciplinary action stemming from a gambling conviction, which also sidelined him for the start of the 2020 season (which he was already going to miss due to injury). He rejoined the team in mid-June.

In 2021, Oh authored an impressive 1.92 ERA through 63 appearances for the Lions, finishing 60 games while also converting 44 saves.

This season, Oh has appeared in 50 games for the Lions and has 26 saves on the year to go along with a 3.24 ERA. He owns a 9.0 K/9 with a 1.280 WHIP while also finishing 41 games this season. Oh has not allowed an earned run through his last eight outings and has struck out at least one batter through nine of his last ten appearances.
