Shota Imanaga struck out seven over as many shutout innings as the second-year lefty picked up his 10th win of the season in the Yokohama BayStars' 4-1 victory over the Chunichi Dragons on Thursday.
Imanaga (10-5) got early run support, with sluggers Yoshitomo Tsutsugo and Jose Lopez hitting back-to-back RBI doubles and catcher Hiroki Minei driving in a run in the bottom of the first inning to put the home team ahead 3-0 at Yokohama Stadium.
The BayStars added another run in the seventh on Tsutsugo's groundout, while Chunichi was able to score only once on Yohei Oshima's groundout in the eighth.
