I assume this time it's real, unlike last Thursday which was full of "he's signing", followed by Grilli denying each report. I only assume this one is real because Rosenthal wasn't involved in the reporting last Thursday, but was providing the best updates on the situation leading up to that date.
I think the question to ask now is "what happens with Joel Hanrahan?"
UPDATE 4:00 PM: If there was any doubt this time, several other writers are confirming the deal. No financial details yet.
UPDATE 4:03 PM: Bob Nightengale reports that Grilli turned down more money from another team to stay with the Pirates.
