Tomochika Tsuboi and Makoto Kaneko hit back-to-back RBI doubles in a three-run rally in the ninth inning as the Hokkaido Nippon Ham Fighters beat the Seibu Lions 8-6 on Sunday to extend their winning streak to five games.

Tsuboi's pinch-hit double tied the game at 6-6 with one out in the top of the ninth. Kaneko followed with a double of his own and Yoshio Itoi added a run-scoring single two batters later at Seibu Dome.

The Fighters took sole possession of the lead in the Pacific League. Naoki Miyanishi (1-0) won in relief.
