The Yomiuri Giants aren't giving up first place without a fight.

Especially not to their fiercest rivals.

Hirokazu Ibata drove in the tiebreaking run in the fourth inning, and the Yomiuri pitching staff, led on this night by Chris Seddon, kept the Hanshin Tigers caged during a 4-1 win in front of a crowd of 46,006 on Thursday at Tokyo Dome.
