He had one at-bat as a pinch hitter in that game, striking out swinging to SK Wyverns pitcher Gary Glover in the top of the seventh inning.

He appeared in only five games with the Twins in 2009, getting one hit and striking out five times in nine at-bats.

During the 2010 season, Oh was impressive enough to earn the starting shortstop job for the Twins over another candidates.

He led the league in strikeouts with 137 but drove in 61 runs, the most in team history by a shortstop for a single season, and hit 13 home runs, the most among the starting shortstops in the league.

After the 2010 season, Oh was selected for the South Korea national baseball team to compete in the Intercontinental Cup held in Taichung.
