Norichika Aoki went 4-for-5 and Masakazu Fukukawa hit a grand slam as the Tokyo Yakult Swallows routed the Yomiuri Giants 10-2 to sweep the three-game season-opening series on Sunday.
Tied 2-2 with none out in the sixth, reliever Shintaro Yoshitake (0-1) issued a bases-loaded walk to Aaron Guiel and Yasushi Iihara hit a two-run double for a 5-2 lead at Jingu Stadium.
Fukukawa's blast to the seats in left in a five-run seventh put the icing on the cake for Yakult. Lefty reliever Masaru Sato (1-0) won his career first decision.
