What does tapping your helmet mean in baseball and when do players use this signal?

I’ve noticed players sometimes tap their helmet during a baseball game and I’m curious what it means. Is it a signal between teammates or coaches, and does it have different meanings in different situations? Can someone explain when and why this gesture is used?

Tapping your helmet in baseball serves as a handy communication signal. It’s often a way for players to show they’re aware of what’s going on or to get instructions. For instance, it can alert a runner to pay close attention to a coach’s sign or confirm that they’ve understood a play call. In Major League Baseball, this gesture is also frequently used to indicate readiness or to acknowledge strategies during baserunning situations.
