(FD) Castillo got smoked by a nearly entirely RH LU at home last time out after pitching poorly in LA (AL) his previous time out. He’s allowed six barrels to Buehler’s two. They may both be toast, but the Padres have a comparable offense, better defense and base running with possibly the best bullpen in the league anchored by a game shortener. (Wouldn’t play much higher)
