The Bears broke open a close game with a four-run seventh inning and added four more in the ninth. Jung Soo-bin homered and drove in three runs, while Yang Eui-ji had three hits and three RBIs.

Lotte starter Kim Jin-uk struck out nine but took the loss, allowing three runs over five innings. The Giants managed only eight hits total. Doosan improved to 9-11-1, while Lotte fell to 6-14-1. The teams meet again Thursday to conclude the series.
