What is the ruling when R3 attempts to hurdle F2, who is kneeling, during a play at the plate?

When R3 attempts to hurdle F2, who is kneeling, during a play at the plate, the ruling is that the runner is out. This situation falls under the rules governing obstruction and interference in baseball. When an offensive player (the runner) deliberately tries to avoid an obstruction by hurdling or jumping over a fielder who is in a position to make a play, it can be deemed as dangerous or reckless, especially if the fielder is in a vulnerable position, such as kneeling.

In this scenario, F2 has the right to occupy their position at home plate, and R3’s attempt to hurdle them is considered an act of interference, leading to R3 being called out. This decision promotes player safety, ensuring that the runner does not put themselves or the fielder in harm's way during a play. It's crucial to remember this ruling in similar situations to maintain the integrity of the game and safeguard all participants on the field.
