Yuki Nishi and the Orix Buffaloes gave the Kansai rival Hanshin Tigers a 12-2 beating on Tuesday, the first day of interleague play.

Nishi (8-0) allowed two runs on eight hits over six innings, while striking out just one batter. His teammates, however, tormented Tigers right-hander Shintaro Fujinami (2-3), who surrendered six runs — three earned — in two innings.

Tomotaka Sakaguchi had three hits and drove in five runs for the Pacific League leaders, who won their sixth straight game.

“This was the first game of interleague play, so it was good to win and get off to a good start,” said the Orix captain. “When runners got on (against Nishi), he really bore down.”

The Buffaloes right-hander apologized for only going six.

“I made extra work for the bullpen, so next time I’ll go the distance,” Nishi said. “As for the streak, that’s something we achieve as a team, and I am grateful to the position players for making it possible. But I’m really just focusing on each game as it comes and trying not to get ahead of myself.”

Orix opened the scoring without a hit in the first on a walk, a sacrifice, an error and an RBI groundout off the bat of Esteban German, who later singled and homered. Sakaguchi made it a three-run first inning with a two-run single.

Buffaloes catcher Hikaru Ito also went deep with a three-run blast.

Otani, who batted seventh, was 0-for-3 at the plate. From the mound, Otani ran roughshod over Chunichi for five innings before a couple of walks led to a five-run sixth inning.

At Yafuoku Dome, Yuki Yanagita went 4-for-4 and opened the scoring for Fukuoka Softbank with a second-inning RBI single.

Hawks second baseman Yuichi Honda became the 28th player to steal 300 career bases in the fifth inning.

BayStars 3, Eagles 2

At Sendai’s Kobo Stadium, Yasutomo Kubo (3-3) allowed two runs in six innings as Yokohama came from behind to beat Tohoku Rakuten.

Giants 9, Lions 1

At Seibu Dome, Frederich Cepeda delivered the game’s first run with a sacrifice fly and hit his second homer for Yomiuri, which crushed Seibu behind seven strong innings from southpaw Toshiya Sugiuchi (4-2).

Hayato Sakamoto, the Giants’ 25-year-old shortstop, had his 1,000th career hit, a first-inning single.
