Kohei Arihara was impressive over seven innings and Haruki Nishikawa drove in four runs to lead the Hokkaido Nippon Ham Fighters to a 10-1 victory over the Fukuoka SoftBank Hawks at Tokyo Dome on Monday.

Arihara (5-2) allowed five hits and hit a batter, while striking out six over seven innings. The only run he allowed came when Seiichi Uchikawa homered to lead off the bottom of the seventh.

It was Arihara's first starting assignment since May 27. After allowing 13 runs over his previous two starts, he pitched four times in relief.
