Al's got it right, and I can testify as a slow-pitch ump that it's the umpire's responsibility to make sure he watches 'his'** runners touch the appropriate bases. I do this as a force of habit at this point, and am surprised how infrequently the defensive team notices that a runner misses a base. I also closely watch 'my'** runners for leaving the base early, and will call them out if they do indeed attempt what Al's talking about. That said, I think it is the wrong thing to teach young men/women to cheat as long as they can get away with it. That lesson applies far beyond sports, and is a poor one for adults to endorse, IMO. Sounds like you have some green umps, and definitely any advantage to be had is a good one, but not at the expense of common-sense ethics. Laugh about it, say, 'Way to be heads-up' if you want to be nice, but reinforcing cheating as blatantly as the example cited, IMO, is poor judgment. While it's not the team's fault the umps stunk, at the same time the mentalitly that you'll cheat until you get caught will really come back to haunt the team at some point. You'll have umps who are on the ball, and will easily call the runner(s) out (or whatever play it may be). There certainly is a way to play 'The Game', whether it be baseball, softball, etc. I value a pure sense of competitiveness, but not one that is just blatantly cheating. That's just my 2 cents. ** - Each umpire is assigned to cover runners at certain bases, so the field ump not seeing the runner blatantly miss 3B is not as troublesome as the plate ump not catching it, as 3B & HP are his/her responsibilities
