Hiroki Kuroda held the Tokyo Yakult Swallows to a run in seven innings and also hit a three-run double as the Central League-leading Hiroshima Carp won 8-1 on Wednesday, claiming their 11th straight game for the first time since 1984.
Former big leaguer Kuroda (6-3) allowed three hits and a walk, fanning four in 93 pitches.
Tetsuto Yamada scored the Swallows' only run with a solo shot over the center field wall in the second, the on-fire Yakult slugger hitting his CL-leading 26th of the season.
