When an infielder catches a ball classified as an infield fly, should all other umpires echo the signal given by the plate umpire?

When an infielder catches a ball classified as an infield fly, it is indeed the case that all other umpires should echo the signal given by the plate umpire. This practice is vital for maintaining consistency and clarity in the game. The infield fly rule is designed to protect base runners by ensuring that they are aware that a fly ball is being automatically ruled as an out, which affects their ability to advance.

When the plate umpire signals for an infield fly, this communicates to everyone on the field, including players and spectators, that the ball is live and the runners must be cognizant of their options. By having all umpires echo or confirm this signal, it ensures that there is no confusion regarding the ruling throughout the field. Clear communication among the umpiring crew reinforces the enforcement of the rule and helps maintain the integrity of the game.
