SENDAI (Kyodo) -- Hiromi Oka hit a two-run second-inning home run that helped power the Lotte Marines to a 5-2 win over the Pacific League-leading Rakuten Eagles on Thursday.
The defeat at Rakuten Seimei Park marked the first time this season that the Eagles had lost consecutive games.
Oka, who drove in the first run in Wednesday's 3-1 win, hit his second home run of the year, off Eagles right-hander Takayuki Kishi (3-1), to put the visitors up 2-0.
Kishi allowed four runs over 6-1/3 innings, while Marines starter, former Eagle Manabu Mima (1-4), allowed two runs over six innings to pick up the win.
Leonys Martin, who walked ahead of Oka's home run, doubled in the fourth and scored on Adeiny Hechavarria's first double of the game. Hechavarria made it 4-2 in the seventh, when he doubled and scored.
Brandon Laird completed the scoring by leading off the eighth inning with his third home run. Closer Naoya Masuda worked the sixth to record his sixth save.
In the Central League, the Yakult Swallows salvaged the final game of their three-game series against the Chunichi Dragons with a 3-1 win, while the Yomiuri Giants beat the DeNA BayStars 4-1 to snap their five-game losing skid.
