I was offered Curtis Granderson and Joel Hanrahan for Jay Bruce.
I do need closer, but my team has underpreformed this year and I'll likely end up dealing Hanrahan for picks next year anyway. It is a 5 keeper league and I already have Fielder, Hanley, Crawford & Posey as 4 of my 5.
looks like a pretty good trade for you anyway - Granderson supplies power and with that lineup, he can put numbers as good as Bruce (maybe). Meantime, Hanarahan is a decent closer - so I think you bolster RP while only taking a small hit at OF.
