When the St. Louis Cardinals signed Seung-hwan Oh last January, expectations were relatively tepid—that Oh could be a solid member of the bullpen, but that he would ultimately play a secondary role to Trevor Rosenthal and more established relief arms.
Oh was following a 2015 season with the Hanshin Tigers of Japan’s Central League in which he had a 2.73 ERA, his worst professional season in half a decade. But in his rookie season in Major League Baseball, Oh posted a 1.92 ERA, with a 2.13 FIP implying that if Seung-hwan Oh got lucky in 2016, he didn’t get that lucky. He appeared in 76 games, leading the team, while throwing 79 2⁄3 innings. Despite not inheriting the closer role from Trevor Rosenthal until late June, Oh led the Cardinals in saves in 2016 with 19.
Was what the Cardinals saw from Seung-hwan Oh in 2016 an aberration, or can the reliever, who turns 35 in July, maintain this level of performance going forward? Most projection systems believe that Oh will be worse, though still fairly effective, in 2017.
