Seth Greisinger was back in his old stomping ground, but for all it mattered, he could've been on the moon.

Greisinger threw 7 1/3 innings of one-run ball and rookie reliever Naoya Masuda recorded the two biggest outs of the night as the Chiba Lotte Marines edged the Hokkaido Nippon Ham Fighters 2-1 on Tuesday at Tokyo Dome.
