Malicious contact after scoring

[DG]

On the second subject:

In Fed, a catcher can not block the plate without the ball. If he does, obstruction, award the runner home. If the catcher has to go up the 3rd base line to receive the throw the runner should avoid him or he might be ruled to interfere with the catcher's ability to catch the incoming ball. If they should contact then the umpire makes big bucks to decide - obsruction, or interference, or incidental contact. Best thing for coaches is to tell the runners to avoid the catchers who are "up the line" and let the umpires rule obstruction. It is also the safest thing to coach, you don't want runners running into catchers. If the ball touches the catcher's mitt a millisecond before the runner makes contact, and the catcher does not hold the ball, I have nothing, unless the contact was malicious.
