Goro's currently in Triple-A for the Memphis Bats as their closer. He joins the major leagues next year(current issues in the manga) and does will for the first start until... he fucks up the last inning of a almost perfect game, hits some batters and loses the game. Then he gets shelled in the next game he starts, and then he gets shelled again in the next game he starts. So the team sends him to a shrink, because they think Goro's still fucked up over giving up a homerun to Joe Gibson's son over at the World Baseball Classic arc.
So yeah, Goro's head is fucked.
