Placing Dirt On The Pitching Rubber
 

What, if anything, would you do as an umpire if a pitcher covers the rubber
before an inning and after you have cleaned it?

Seriously, do you as an umpire see a violation by this action?

I know of no rule that this violates... was her footwork suspicious? Perhaps she was trying to make it difficult to see if she was properly contacting the plate.

I'd place my brush in my ball bag and keep it there throughout the game. :D

You do absolutely nothing in ASA.

They always cover it back up.

Hey, this ain't the small ball board! ;)

Hmm.. I thought they kept in in their fanny pack on the bases.

Right next to their hidden indicators.

Speaking ASA

It is nothing as long as you know the location of the pitcher's plate. If you suspect a pitching violation and you are unsure of the location of the PP, would only need to call that once to get the point across that you need to see some portion.



edited to add ASA

So what is the call again?

"I suspect you arent on the dirty plate so I called it"??

Hope I'm never on the field with a partner dumb enough to make that call.

There is an NCAA rule.
2.15.2 A player shall not intentionally remove any lines in the batter’s box or
on the field nor intentionally cover the pitcher’s or home plate.
A.R. 2.15.2: Deliberately covering a line with infield material is considered
removing the line.
EFFECT—A strike shall be called on the batter if the offense intentionally
violates the rule and a ball shall be awarded to the batter if
the defense intentionally violates the rule.
Notes:

Laugh, maybe. :D
