Amendment-Minor leaguers called up prior to auction

[Oregon Three Lions of Madison]

If you call up a minor leaguer prior to the MLB auction(i.e.. if he is on your roster during the MLB auction) that players MLB contract will begin. You can send him back down to your minor leagues before the season starts, but again, his MLB contract will have begun.

I am not certain how this was handled, or if it was handled consistently in the past by looking at certain players that are rostered right now.
