The Seibu Lions and Chiba Lotte Marines traded errors and three-run half innings in the opening frame of their matchup on Friday night.

The Lions took care of everything after that.

Tomoya Mori nearly grazed the back wall with a solo home run in the third and connected on an RBI double during a three-run eighth as the roaring first-place Lions beat the Marines 9-3 at QVC Marine Field.
