Who said R.A. Dickey is going to be a Blue Jay?

So my weekend was kind of ruined by the fact that RA Dickey is apparently going to be a Toronto Blue Jay.

I seriously spent at least 8 hours watching Twitter, in a mall's food court, while pretending to Christmas shop, waiting for the allegedly immanent trade to become official.

Ironically, neither the trade nor my Christmas shopping is done.

It got me thinking, though. Who is telling Ken Rosenthal et al about these trades?

Is it someone from the Jays? If so, who? How close are they? Are they THIS close:
