Seth Greisinger pitched one-run ball over six innings, setting the pace as the Yomiuri Giants handed the Yokohama BayStars their season-opening sixth loss in a row in a 9-2 rout on Thursday.

Greisinger (1-1) surrendered a game-tying solo homer to Yuki Yoshimura, who is batting cleanup for injury-hit Shuichi Murata, in the second but settled down later, allowing four hits with six strikeouts and a walk in Central League action at Yokohama Stadium.

Michihiro Ogasawara had four RBIs, giving the Giants the lead with his second RBI double in the third and adding a two-run double in a four-run seventh. Kazunari Tsuruoka went 3-for-4 with a two-run homer in the eighth for Yomiuri, which won its third straight.
