Yurisbel Gracial hit the second grand slam of the game in the 12th inning Sunday to help the Fukuoka SoftBank Hawks earn a 12-8 walk-off win against the Seibu Lions and a series sweep to move within five games of the Pacific League leaders.

Prior to Gracial's late heroics, Yuki Yanagita and Kenta Imamiya, who hit the game's first grand slam, drove in a combined eight runs as the defending Japan Series champs won their ninth straight.

"I needed to hit in that situation and the fans' support helped me get it done," Gracial said of his fourth home run of the season. "It doesn't matter who you are, any batter in that situation is going to find it hard to get a hit, but I tried to relax, hit the ball hard and bring in a run.
