Professional baseball Doosan Bears has only won one win in three years of regular league-Korean series combined championship.

Doosan beat Kiwoom Heroes 5-0 in the 3rd round of Shinhan Bank's Maika KBO Korea Series held at Gocheok Sky Dome, Seoul, with a starter pitcher Seth Hulankov's six-inning loss.

Doosan, who won three games in a row after winning the first and second consecutive games, is ready to recapture the summit in three years since winning the combined championship in 2016.

So far, all ten teams that have won the first three games in the Korean Series have won the championship.
