In response to cassvt2004's comment:
I was at the game in Bradenton last spring against the Pirates when Bailey hurt himself covering first base. Knowing he was the Sox projected closer, I immeadiately thought "this isn't good". Sure enough, he was out until early August. When he did come back, the Sox were a mess and out of any contention. Closer's thrive on adrenaline and save opportunities. There was neither to be had for him. He came here as a proven closer but it just didn't happen for him in 2012. Then the Sox saw a deal for Hanrahan because the Pirates weren't going to be able to afford him. Appparently they liked Joel better than Andrew. This doesn't mean that Bailey can't close games any more or doesn't have trade value.
On a side note, I'm glad that I could start a thread that my vote for top 3 posters of the year (Notin, Moon, & Drewski) all commented on. Good stuff.
The deal for Hanrahan was alo made with the possibility that, if the season unfolds poorly, Hanrahan, and not Bailey, is the reliever moved in July. He is a free agent after 2013 anyway, and there are always one or two teams looking for closers in July, and EVERYONE who still thinks they are in it is shopping for releivers...
