Catcher Tatsuhiro Tamura had four hits and three RBIs to help power the Chiba Lotte Marines to a 10-4 thumping of the Seibu Lions in the Pacific League on Sunday afternoon.

Tamura doubled, homered and added a late RBI single, and Jason Standridge (5-5) pitched into the sixth inning as the second-place Marines bounced back from an extra-inning loss the night before.

"We have been giving up runs often, so we have been forced to score a lot," Tamura said. "I made some adjustments with coach Hori (batting coach Koichi Hori), eliminating some excess movement and working to get a better look at the ball.
