Wada started the 2010 campaign pegged as the fourth starter in the rotation behind Toshiya Sugiuchi, Kenji Ohtonari, and D.J. Houlton. His first start of the season came against the Orix Buffaloes, and he gave up two runs on three hits in five innings, walking two and striking out eight. Despite the performance, he took the loss. More of the same came from Wada in his second outing against the Saitama Seibu Lions, as he gave up four runs on five hits in five innings, but he managed to get the win.
