Casilla’s cool demeanor belies competitive fire within
Santiago Casilla keeps his emotions mainly to himself, unlike a large percentage of his counterparts, who favor gesticulations, primal screams or both when they’re on the mound. “I am emotional, but I try to keep that inside,” Casilla said. “It depends on how I feel. I’m not going to show it just so people can see it, but I really am amped up.”
