Pinch hitter Yoshiyuki Kamei hit a three-run walkoff homer with no outs in the ninth inning to give the Yomiuri Giants a 5-4 victory over the Chunichi Dragons on Saturday.
Kamei drove the first pitch he saw from Hitoki Iwase (0-1) over the center-field wall at Tokyo Dome, following back-to-back singles from Alex Ramirez and Yoshitomo Tani.
Kamei's first homer of the season came after Kazuhiro Wada's tiebreaking two-run homer put Chunichi up 4-2 in the top of the ninth.
