What is the outcome of B4's hit if he intentionally interferes with F3's throw?

When a player intentionally interferes with a throw from the fielding team, it constitutes a violation of the rules. In this scenario, B4's intentional interference with F3's throw means that B4 is demonstrating behavior deemed unsportsmanlike and contrary to the principles of fair play.

According to the rules, when a runner interferes intentionally with a fielder attempting to make a play, that runner is typically declared out. This is designed to maintain order in the game and ensure that fielders have the opportunity to make plays without unwarranted disruptions. Therefore, the correct outcome of this situation is that B4 is out for interference, reinforcing both the rules intended to promote fair competition and the consequences of actions taken by players on the field.

As such, the ruling applies regardless of the likely outcome of the play had the interference not occurred. This serves to deter players from engaging in similar unsportsmanlike actions in the future.
