When the children arrive at the ball game, one of them asks Rebecca what the score is. She answers "3-2, but the other team has the bases loaded, and there is only one out." Nathan then strikes a man out, and his son calls out to him "Two more to go, Daddy!" But if there was already one out, he should have shouted out "One more to go." Nathen the picks a man off base, and that should have finished the inning and game with that being the third out. Instead, Nathan's son calls out "One more," and Nathan then pitches to another man, striking him out too, for a fourth out.
