Taketoshi Goto hit a three-run home run in the early going as the Yokohama BayStars downed the Central League-leading Yomiuri Giants 3-0 on Wednesday night.
Yasutomo Kubo (7-4) yielded five hits over six innings for the win and three relievers polished off the shutout as Yokohama stopped a three-game-losing skid with a victory at Okinawa Cellular Stadium.
After a two-out double by Takayuki Kajitani and Yoshitomo Tsutsugo drew a walk in the first inning, Goto took Giants starter Tomoyuki Sugano deep to left on a first-pitch offering.
