Need clarification on obstruction call

[Klokard]

At any time did the catcher block the runner from reaching the plate without the ball? If so, obstruction in FED. If not, then without being there and seeing the play, sounds like the catcher did his job. Remember, for obstruction to happen, the catcher must block all of the plate without the ball. If he offered any of the plate at all for the R3 to slide into, we have no obstruction. If the catcher received the ball prior to the slide, great play by the catcher. That's how I would have called it.
