Blue Jays sign Korean pitcher Woo-jin Cho to an MiLB deal

The Toronto Blue Jays have added some pitching depth to the minor leagues.

Per the MiLB transactions page and Nolan on X, the organization signed Korean right-hander Woo-jin Cho to a minor league deal earlier this month, and he has been assigned to the Dominican Summer League roster.

Pitching for Jangan High School, Cho is 18 years old and works with a low-90s fastball combined with a slider, curveball, sinker, and a changeup.

Across 45 innings and 12 high school games, the sidearmer pitched to a 3.20 ERA with 60 punchouts, demonstrating a high strikeout count on the mound. Standing at 6-feet tall, it’s still to be determined whether the Jays plan to have him start games in 2027 or use him more as a reliever, or whether he will continue to work in the DSL next season or if he will move to Florida to take part in the rookie ball there.

Cho is just a handful of pitchers the Jays have signed out of Korea over the past two years.

Seojun Moon signed with the organization in September 2025 after a stellar high school career. Standing at 6-foot-4, Moon posted a 6.53 ERA across 11 outings and 30.1 innings this past season in the Florida Complex League with Dunedin. This included a 1.747 WHIP and a 9.2 K/9.

Toronto also signed Kwon Si-Woo back in September, worth $330,000. Si-Woo features a fastball in the low 90s and works with a slider and a curveball with a high release point and has yet ot appear in affiliated ball thanks to the late signing.
