In his 11 seasons across the Korean and Japanese professional leagues, Rockies reliever Seunghwan Oh dominated with a 1.81 ERA and 357 saves to cement his “Final Boss” nickname.
But Oh, now in his fourth major league season, is struggling worse than ever. He had a 2.78 career MLB ERA coming into 2019, but entering play Friday his season ERA was 7.90 in 15 appearances.
“The problem is elevated pitches, especially the fastball,” Rockies manager Bud Black said. “He’s going to pitch up in the zone a little bit — that’s what he does — but he’s got to incorporate the low fastball as well.
