A Doosan rookie, Seo Jun-oh, nicknamed Korea's Yamamoto, is sweating it out at the Miyazaki camp in Japan.
Seo Jun-oh, who attended Dongsan High School and Hanyang University (early admission), was selected by Doosan with the 27th pick in the third round of the 2026 rookie draft. In his third year of high school he suffered the disappointment of going undrafted as his small stature and a maximum fastball velocity of 141 km limited him, but after enrolling at Hanyang University he achieved a turnaround by increasing his velocity to 153 km in two years. Seo is being evaluated as an immediate bullpen asset for the 2026 season.
