As a parent of a youth baseball catcher these types of plays are both exciting and a bit scary. Even though the runner is required to slide in youth baseball, plays at the plate are often rough.
In the pros, the catcher is allowed to block the plate without the ball and the runner is allowed to knock the catcher over. Super Star catcher Buster Posey of the San Francisco Giants knows this all to well. He was recently involved in a nasty collision at home plate and broke his leg. In youth baseball, the runner is required to slide or he / she will be called out automatically. If the runner knocks the catcher over the player will be called out and may be suspended for a game.
How to block the plate
My son, Nic, demonstrates an almost text book execution of how to block the plate without getting hurt in the following 5 pictures.
Hot grounder down the line. Runner moving on contact. Nic moved up the first base line slightly to give the 3rd baseman a direct line to throw the ball pass the runner. The ball was thrown in the dirt. Nic was able to pick up a tough hop because he was waiting for the throw in an athletic position (like a SS would await a ground ball).
