Okay . . . I am going to guess why Yost did not pinch hit. 1) You need a pinch hitter for the pitcher coming up. 2) You will need a pinch hitter later in the game for the next reliever who has to bat. . . or you will need someone to go in after a double switch. Miller, Hart, Mench, Graffanino are left. Miller can't pinch hit because you need a backup catcher. Perhaps Ned was more concerned about being short-handed later?
