Ryosuke Miyaguni allowed a run in six steady innings on Wednesday, helping the Yomiuri Giants beat the Yokohama BayStars 4-1 after the Central League leaders dropped their series opener the night before.

John Bowker homered for the second straight night, giving the Giants the lead in the second inning with his 11th homer of the year, a two-out, two-run shot off BayStars starter Kota Suda (3-2).

The BayStars halved that deficit in the top of the third, when Norihiro Nakamura's two-out single off Miyaguni (5-5) scored captain Takehiro Ishikawa from second.
