Close play at second

[Gre144]

Today, I was by myself and I called the R1 who was stealing to second out on the tag. From the sound of the crowd and the expression of the offensive coach, I think I might have made the wrong call.

Can anyone give me some advice that will help me make the right call on a close play at second,third or home? Assume that we are talking about a tag play and not a force out. I especially want to know if the positioning of the tag on the runner is the most important aspect in making a decision or do you focus more on whether the ball got to the ball before the runner?

Thanks
