-- Nick Piecoro

Sources: #Dbacks close on Cahill. RHP Jarrod Parker, OF Collin Cowgill in play for #Athletics. Could be others coming from A's. #MLB... expected to receive Breslow as well as Cahill
-- Ken Rosenthal

But:

The #Dbacks plan on Parker being their 5th starter so he is NOT in potential deal
-- Bob Nightengale

That's the latest info. What, no Trevor Bauer? But I was told... We'll update as things progress, please discuss and post any verifiable reports in the comments.
