In baseball, each team's defensive players must know the order in which the opposing team's batters will hit. This information is recorded on cards kept by the outfielders, and they consult these cards before each pitch to help them make decisions about positioning and strategies.
There are a few reasons why outfielders look at cards before each pitch. First, it helps them remember the order of the batters. Second, it allows them to anticipate what type of play might be coming their way. Finally, it gives them a chance to adjust their positioning based on the current batter and situation.
Looking at cards may seem like a small thing, but it can make a big difference in the outcome of a game. Outfielders who take the time to study the batter cards can gain a significant advantage over those who don't bother with this step.
