Rookie southpaw Haruhiro Hamaguchi tossed seven solid innings as the Yokohama BayStars defeated the Hiroshima Carp 6-2 on Thursday to pick up their first win in the final stage of the Central League Climax Series.

On offense, CL batting leader Toshiro Miyazaki went 3-for-5 with three RBIs and pinch hitter Tomo Otosaka drove in two runs to ignite the third-place team's revenge against the Carp, who now have a 2-1 lead in the six-game stage, including the one-win advantage as league champion.

A day after a frustrating loss in Game 1 that was called after five innings due to rain, the 22-year-old Hamaguchi (1-0) struck out six and gave up two runs on seven hits and a walk in his 128-pitch effort at Mazda Stadium.
