Game Management Opinion

[CecilOne]

Please consider this play:

Play: With R1 on 1B, B2 has a 2-1 count. The next pitch is a ball and B2, thinking it is ball 4 heads to 1B and R1 advances to 2B. The plate umpire states that was only ball 3, so B2 comes back to bat with a 3-1 count. What happens to R1?
Ruling: In this play the offensive and defense have the responsibility to know the count. When R1 advanced to 2B the ball remains live as if they were stealing. B2 would be returned to bat and R1 would remain on 2B.

What do you think of the following comment versus allowing the play?

However this is a great preventative umpire situation. When the plate umpire sees B2 start to 1B, call time and now nothing can happen and we will have less of a problem than if we had allowed the play to continue.
