ASA Rules Question From Prospective Ump

[greymule]

I remember calling it once, after the BR touched 1B but saw F10 under his pop in short RF. He retreated back down the 1B line, but F10 dropped the ball. The BR tried to make it to 1B, but the throw beat him.

I can't remember having that call any other time.

It's most likely to happen on a play like this:

Abel on 1B, no outs. Baker hits a liner to short RF. Abel runs and touches 2B as F10 dives for the ball but traps it. Abel thinks F10 caught the ball and starts to return to 1B. F10 throws to F6 at 2B for the force out on Abel, even though Abel had touched 2B.
