Meiji Jingu Stadium
Dening made his debut on the same day as his presentation to the media playing as a pinch hitter against the Hokkaido Nippon Ham Fighters at Meiji Jingu Stadium. On 29 May, Dening hit his first NPB homerun in a game against the Fukuoka SoftBank Hawks. He would then go on to hit his first grand slam on June 7 against the Chiba Lotte Marines. However, with the return of Milledge to the team, Dening was dropped from the side where he found himself out of favour. He finished the season having played 64 games registering 4 homeruns and 22 RBIs. While he was listed for possible action in the 2015 Japan Series he did not see any further action during the season.
