Shoichi Ino struck out a season-high nine over seven innings and two relievers provided perfect relief as the Yokohama BayStars whipped the Chunichi Dragons 9-0 on Saturday.
Ino (4-4), who allowed five hits, walked a batter and hit one, and struck out four of the first five hitters he faced before the BayStars opened the scoring in the top of the third.
Masashi Kuwahara, who went 3-for-4 with a solo homer and three runs, got things going in the third against second-year lefty Shinnosuke Ogasawara (2-4).
