Soma Yamauchi pitched seven scoreless innings and Ryosuke Hirata homered as the Chunichi Dragons held off the Seibu Lions 3-2 in interleague action at Nagoya Dome on Saturday.
Hirata hit a two-out, solo drive in the second inning and Masahiro Araki's suicide squeeze followed Yohei Oshima's one-out triple for the second run in the third. Motonobu Tanishige doubled down the right-field line to plate the decisive run in the seventh.
"I was glad to get the opening run for us, and I just hoped that Yamauchi-san would shut them down after that," said Hirata. "I thought it would hit the fence but the ball got some good lift and went over."
Yamauchi (4-2) scattered three hits, struck out four and walked one. Hitoki Iwase worked the ninth for his 15th save. Seibu saw its winning streak end at four games.

At Yokohama Stadium, Katsuya Kakunaka's two-out, RBI double sparked a three-run fourth inning, and Yoshihisa Naruse (4-2) limited the damage to two runs against Yokohama in six-plus frames as Chiba Lotte extended its undefeated run to seven games.
Lotte, which moved a season-high 10 games above .500, strung together four consecutive hits off Kentaro Takasaki (1-4) with two outs to grab a 3-0 lead in the fourth. Yokohama came within 3-2 in the seventh, but Lotte pinch hitter Masahiko Tanaka drew a bases-loaded walk in the ninth.
Carp 1, Fighters 0
At Mazda Stadium, Yusuke Nomura combined with two relievers in a five-hit shutout, and Eishin Soyogi homered off Yuki Saito (4-3) in the sixth for the only run necessary as Hiroshima downed Hokkaido Nippon Ham.
Nomura (3-3) gave up five hits while striking out six and walking two. Hiroshima won back-to-back games for the first time since a three-game sweep of Yokohama on April 17-19.
