I don't think I would. I'm not too sure though. I think Bogaerts is a special talent (kind of like a Hanley in terms of blue chip prospects) and I would value one higher at SS than SP. In addition, we'd have 6+ starters in Sale, Lackey, Lester, Dempster, Doubront, and Buchholz. Granted that problem could be solved in the offseason. In addition I feel like our present needs for the team are in the bullpen, and perhaps 3B, rather than SP.
On the flip side, Sale is an exceptional pitcher thus far, and in the postseason you need at least 1 ace. 2004 was aided by our trade for Schilling, and 2007 was aided by our trade for Beckett (albeit getting rid of Hanley and Anibal in the process) In addition, with Buchholz hurt and Lester sucking, we really need that ace pitcher in the postseason, and a 1-3 of Buchholz, Sale, and Lackey would be difficult to beat. Another argument for is that Sale would make Webster expendable and Workman is a nice piece but not one I'd lose sleep over.
On paper I think it's a good deal for us but I don't think it matches what we are looking for (and looking to give up) this season.
