In the second, Hiroshi Narahara led off a six-run attack with a run-scoring hit, while Tanaka followed with his 10th roundtripper of the season. Tatsuya Ide capped the inning with a solo homer.

Nippon Ham starter Tsuyoshi Shimoyanagi pitched well by scattering two hits over four-plus innings, but left the mound in the fifth inning with an injury and lost the right to claim the win.

The Fighters sent four relievers to hold on for the victory. Yoshinori Tateyama (1-0) picked up the win and Carlos Mirabal earned the save.

Fumitoshi Takano nailed a two-run homer for the Buffs, who lead over the second-placed Daiei Hawks by only .001.
