Kazuhiro Kiyohara drilled a game-winning homer in the bottom of the ninth inning and the Yomiuri Giants extended their winning streak to four with a second straight "sayonara" victory over the Yokohama BayStars at the Tokyo Dome on Saturday.

The BayStars out-batted the Giants 13-6 but left 13 stranded on base as they lost 8-5. Akira Eto had two homers for Yomiuri -- a two-run clout in a three-run fourth and a solo homer in the eighth.
