What is the ruling on F1's jump turn in Situation J?

In Situation J, the ruling on F1's jump turn is that it is legal as long as he throws. This is based on the understanding that a pitcher may execute a jump turn if they are making a play on a runner or attempting to throw to a base.

The key factor is that F1 must legally throw the ball after the jump turn. The action of the jump turn itself is not prohibited; rather, it becomes a question of whether the pitcher remains within the rules concerning their delivery and throwing motion. If F1 successfully executes the throw following the jump turn without violating any pitching regulations, then the play is allowed.

Understanding the nuances of different actions on the mound is crucial for players and coaches, particularly in how they can use their movement to defend against base runners while still complying with the pitching rules set forth by the NFHS.
