Shinji Sasaoka tossed a five-hitter for his ninth victory of the season -- the best in Japan this year -- against one loss as the Hiroshima Carp blanked the Yokohama BayStars 3-0 at Yokohama Stadium on Friday night.
Sasaoka walked one and struck out three to pick up his career 100th win.
The lowly BayStars suffered their seventh straight defeat, their longest skid in four years.
