The Lions blew the game wide open in an eight-run fifth inning before a sellout crowd of 23,550 fans, while starting pitcher Won Tae-in tossed five innings of one-run ball for the victory.

Captain Koo Ja-wook went 3-for-5 and scored twice en route to earning the Korean Series MVP award.

The Lions lost the series opener Tuesday on the road in Suwon, just south of Seoul, but then won the next four games in a row, including the past three at their home in Daegu.
