ASA 10 and Under

[Ump_Dan]

Had a play in a ten and under game in the past tournament I would like the know what the ASA ruling might be.

The Situation:
ASA rules
Cold plate
Runner on first, no outs.
Catcher attempts a pick-off of the runner at first.
Ball goes off F3 glove out of bounds.
I award the runner two bases.
Defensive coach challenges saying that the ASA one base per pitch rule applies, so the runner should get only second.
UIC agrees and places the runner at second.

It had no impact on the game because the runner later advances and scores.

This a play that could reasonably happen again so I would like to know if this is the proper application of the ASA 10 and under rules.
