Kazuto Taguchi threw a six-hit shutout on Sunday to lead the Yomiuri Giants to a 4-0 win over the Yokohama BayStars.
Taguchi (4-1) was tagged with his first loss of the year a week ago but recovered with a 116-pitch effort and issued no walks at Yokohama Stadium.
The Giants led 4-0 by the fourth inning and when the lefty had runners on the corners with one out in the sixth, Takayuki Kajitani grounded into a double play to end Yokohama's best scoring chance of the game.
