This happened Sunday.
We had a runner on 1st, 0 out
Grounder to 1B, tags first and throws to second and nails our runner in the back. He whimpers. I am coaching first and yell for him to get to the base...2B tags him 5 feet from the base and BU calls him safe and calls time.
I jog out to check on the kid and the BU is hearing all sorts of exasperated hollering from the Defensive team's dugout. After about 90 seconds, I convince the kid that he is ok and when I turn around, BU says I think he should be out. I said, "Nope, too late. You called him safe." I turned around and jogged away and heard him say but, but....I never looked back.
The PU told me a couple of innings later that the BU had thought that the runner was awarded the base because he was hit.
