Hisayoshi Chono and Casey McGehee put the Yomiuri Giants in position for a win over their crosstown rivals.
Hayato Sakamoto made sure they got the job done.
Chono drove in four runs, McGehee had an RBI-single among his four hits and Sakamoto put the game away with a two-run homer in the eighth inning to help the Kyojin beat the Tokyo Yakult Swallows 8-5 on Friday night in front of a crowd of 46,851 at Tokyo Dome.
