Five innings from ace Chihiro Kaneko and Takahiro Okada's first grand slam in six years lifted the last-place Orix Buffaloes to a 6-0 win over the Pacific League-leading Fukuoka SoftBank Hawks on Monday afternoon.

"It's been a while since I hit one on the screws," said Okada, the Buffaloes' cleanup hitter, who broke open a scoreless game in the third. "You can't do better than that."

Kaneko (4-6) won for the first time since May 20, pitching out of jams in the first and second innings. The right-hander, who returned to the mound on July 7 after missing nearly a month with shoulder pain, had to leave after five innings due to stiffness in his lower back.
