I would like to understand the meaning of the phrase “to sit in the catbird seat”. It is assumed to express an advantage like the one held by “a batter with three balls and no strikes on him”. I do not have any baseball knowledge so I would like to know if this situation of a batter with 3 balls and no strikes on him gives a position of superiority or of influence. Or is it a somewhat hidden advantage? Please describe in which way.
Thank you very much,
