Yuki Yoshimura hit a two-run homer and rookie right-hander Naoki Mitsuhashi and three relievers combined on a five-hit shutout as the Yokohama BayStars beat the Central League-leading Chunichi Dragons 4-0 for their third straight win Saturday.
Yoshimura sent a 1-0 curveball from veteran lefty Masahiro Yamamoto (7-7) over the left-field wall in the sixth inning, giving Yokohama a 3-0 lead, and Mitsuhashi (2-0) allowed just three singles and three walks in six innings in his first career start.
Seiichi Uchikawa got Yokohama on the board with a fourth-inning RBI single. Kazunari Tsuruoka capped the scoring in the game at Nagoya Dome with a run-scoring single in the ninth.
