Rookie right-hander Masaya Kyoyama pitched 8-2/3 strong innings and Masayuki Kuwahara scored the go-ahead run on a second-inning home run in the Yokohama BayStars' 9-1 triumph over the Chunichi Dragons on Friday.

In front of 26,099 at Yokohama Stadium, Kyoyama (6-5) took the mound with one out in the first inning and limited the Dragons to seven hits, while striking out six. The 20-year-old surrendered his only run to the first batter he faced, Yota Kyoda, who belted a home run.

The BayStars tied it in the bottom of the inning after Yamato Maeda doubled, went to third on a groundout to second and came home on Neftali Soto's sacrifice fly. Kuwahara homered off right-hander Ryosuke Oguma (3-4) in the following inning to give the home team the lead for good.
