Oh was the Cards' third pitcher to appear in the ninth. With the Cards leading 11-8, Matt Bowman got Jose Osuna on a fly ball to right field, but walked two batters straight and hit another to load the bases. Zack Duke replaced Bowman, but the left-handed pitcher also gave up a walk to Josh Bell and let the Pirates cut the deficit to 11-9. 

Oh then came up on the mound to secure the lead. The 35-year-old South Korean started the inning with a sacrifice fly to David Freese, which brought the Pirates within one with the tying run on third base. 

Oh next intentionally walked Adam Frazier to load the bases and faced Elian Diaz. On a 2-2 count, the Korea Baseball Organization's all-time saves leader got Diaz swinging on a slider to wrap up the game. 

With Trevor Rosenthal now on the disabled list, Oh is expected to regain the closer role that he served during last season. He went 6-3 with 19 saves in 76 games last year, marking a 1.92 ERA. (Yonhap)
