I think you did the right thing in this situation...except that jicone brings up an interesting point. You are the senior umpire and therefore have an obligation to protect, teach and coach the less experienced umpire. But this brings the question - when do you let your partner swim for himself. In this case, I think this was the right time to let him sink with his call.

I would definately talk with my UIC about this kid -either he straightens up or goes away.

About the coach for black - I would be concerned about his coaching skills if he failed to at least argue a little bit about this call.
