Due up意思
"Due up" is a term that is commonly used in baseball to indicate that a particular player is next in the batting order to bat. It means that the player is due to bat next, based on the lineup that has been established for the game.
For example, if the bottom of the first inning is over and the top of the second inning is about to begin, and the announcer says that "Player X is due up," it means that Player X is the next batter for the team that is about to bat.
The term "due up" can also be used more generally to mean "scheduled to happen next" or "expected to occur in the near future." For example, if a meeting is about to start and the chairperson says that the next item on the agenda is "due up," it means that it is the next thing that needs to be discussed or addressed.
