Cleanup hitter Seiya Suzuki went deep twice as the Central League-leading Hiroshima Carp scored all their runs on four home runs, beating the Yokohama BayStars 6-1 behind eight strong innings from Akitake Okada on Saturday.

Okada (3-1), who was 4-3 with a 3.02 ERA last year as a rookie, allowed a hit each in his first four innings but no runs until the eighth at Yokohama Stadium. He struck out six while scattering six hits and a walk in a 122-pitch outing.

Hiroshima led by two runs after as many pitches from Yokohama starter Shota Imanaga (1-2), Kosuke Tanaka singling off the lefty before Ryosuke Kikuchi connected on a fastball away for an opposite-field homer to right wall.

Imanaga recovered to retire his next 10 batters — including three strikeouts in the third inning — but was caught by Suzuki in the fourth with one out, who pulled it out to left.

“I’ve been passive recently so I was looking to swing whenever chances come my way, and I got to swing the way I’m capable of,” said Suzuki. “I just went for it and that paid off.”

Imanaga surrendered his third homer of the day in the seventh with one out to Takahiro Arai, who went 3-for-4. Imanaga allowed four runs on eight hits and a walk, while striking out six over 6⅔ innings.

It could have been worse for Imanaga as he left with the bases loaded. Shingo Hirata retired Kikuchi to end the inning, but the reliever issued a leadoff walk in the eighth before Suzuki, whose previous eight games as cleanup came in the absence of Arai, took him deep.

“I want him to think about overtaking Arai and grabbing it (the cleanup spot),” Carp skipper Koichi Ogata said. “If he can make his presence felt in this kind of manner then that possibility gets even higher.”
