I cringe every time I see some kid on the mound just digging, digging, digging. Just like the kid that goes around burning rubber in his car at every stop light (you know that kid doesn’t buy his own tires), the digger has never had to maintain a pitching mound. Now, the landing area is totally different. That’s just plain laziness (or incompetence) of a grounds crew. That should be at a minimum, filled and raked after every game, but at most parks you will never see that happen - just like you don’t see them re-line the batters box or foul lines. If there is no grounds crew between games, then it’s up to the coaches to make sure there is a safe playing field available for their kids. It doesn’t take much time to take a cup or two of water out to the mound, kick the dirt back into the holes, water it and compress it as best they can. Of course, I’ve seen some fields that haven’t been worked in weeks, those are the places you just don’t go back to.
