Lowell, Lowrie, Lugo, Youkilis.
With talks with the Tigers cooling off, Lugo needs to be ditched asap. Pay part of his salary. His stock is not going to go up anytime soon.
The Sox need a dangerous 30 HR hitter. Texeia would be a great signing, but would also increase the logjam. Ideally, an outfield that is a a more dangerous hitter than Jason Bay woud be ideal. But the Sox will probably not trade Bay, since he is fairly cheap ($7.5 million) for next year.
I would say trade JD Drew, but he has to be viewed as damaged goods, despite is All Star MVP aware and clutch post season hitting.
Make no mistake, the Sox have their hands tied in more ways than one. I think they'll sign or trade for a 30 HR hitter, then try to make moves during spring training. Look at it this way, Coco was hurt in Spring Training, but keeping him for the year worked out quite well.
