I believe it was some tome in the early evening, around 6:00 or so, altho I didn't find out about it until later.

I usually do my team for the next day around 8 or 9 PM, to make sure that no games on the East Coast or in the Midwest are encountering weather problems.

I didn't find out from ESPN, though. They still had a DH listed as late as this morning I believe. But I do have some other sources, of course. As, obviously, does everyone else who knew there would be no DH today.
