Katsuya Kakunaka hit a tiebreaking single with two outs in the sixth inning as the surging Lotte Marines went on to beat the Softbank Hawks 3-2 on Sunday.
Kazuya Fukuura and Shoitsu Omatsu had RBI doubles down the right-field line in the second before Softbank designated-hitter Wily Mo Pena hit a two-run homer to tie the game in the fifth. Kakunaka then singled to center to drive home Toshiaki Imae from second, giving Lotte the lead for good at QVC Marine Field.
''I got a good swing on the pitch,'' said Kakunaka, who was the hero for the second day in a row after hitting a walkoff sacrifice fly in the 11th inning in Saturday's game.
Kakunaka, who began the season on the farm team before being called up and is batting fifth in the lineup, has six RBIs in his last nine games.
''This is the first time this year that I was able to have a really good read on a pitch,'' he said.
Shingo Ono (1-0) pitched two scoreless innings to get the win in relief, and Yasuhiko Yabuta worked the ninth for his 11th save. Softbank outhit Lotte 14-5 but stranded 15 runners and dropped three in a row for the first time this season.
