If B1 steps out of the batter's box without requesting time while F1 is communicating with F5, what will be the consequence?

In this situation, when B1 steps out of the batter's box without requesting time, it compromises the game's flow and the pitcher's ability to play. The rules dictate that the batter must either remain in the box or formally request time before stepping out. Since B1 stepped out while F1 (the pitcher) was engaged in communication with F5 (a fielder), the proper call is to penalize B1 by adding an additional strike. This rule is in place to maintain a certain level of discipline and engagement in the game, ensuring that batters do not stall or disrupt the pitcher's rhythm without a valid request. The addition of an extra strike serves as a deterrent against such actions, promoting a smoother progression in the game.
