I honestly look at this more as possible leverage against Abreu signing an extension, rather than Abreu being marked as trade bait. I'd be shocked if Abreu is moved. Jimenez and Moncada have already praised him this year for helping them. Matt Skole is literally the next legitimate, pure 1B in line if Abreu goes down. I would think that Alonso was supposed to be that guy, but we all know how that ended up. Probably signals the Sox also realize Palka and Collins are not long term solutions at 1B. Low-risk, high reward type of move. Regardless, I'd expect nothing to really come of it.
