On a night of dueling home runs at Tokyo Dome, Adam Walker had the final say.

Walker hit a solo homer to deep center to break a seventh-inning tie, and the Yomiuri Giants held on for a 5-4 win over the DeNA BayStars at the Big Egg on Wednesday night.

Walker was making up for missed opportunities in his fourth at-bat of the game after failing to drive in runs with runners in scoring position in the second and fourth innings.
