Lee drove a two-out solo shot off Tsuyoshi Kikuchihara (0-1) into the right-field stands of Chiba Marine Stadium after Orix came back from a three-run deficit to tie the game in the seventh on an RBI single by Hiroaki Onishi and a two-run single from pinch-hitter Daisuke Hayakawa.

Dan Serafini pitched 6 1/3 innings and was charged with three runs before the Lotte bullpen held on. Yasuhiko Yabuta (1-2) worked a scoreless inning to earn the win and Masahide Kobayashi got the final three outs for his fourth save of the season.
