Pressly to start the inning isn't a bad choice. Sometimes he's bad, but a lot of times he's pretty good. But in any case he's miles better than sending Colon out there again, hoping for more luck. I've said this before, I'll say it again: Lose a game late with the bullpen? That's probably on the bullpen. Lose a game late with your starter? That's probably on the manager.
It's a mistake to bring Colon out for the 7th, and I don't care what the result is. You have like 10 relievers out there. Heck, it was questionable to bring him out for the 6th.
I think Dougie Baseball reacted poorly, and don't think he really fit in this regime...AND think Falvey, or at least Levine, need to make that call. He's a field manager in your organization, he deserves to hear the news from the top.
