Is Giambi still out there? I would imagine he might be considering this is only a six team league -- he has found his stroke, and can help you a lot from the 1B pos. because Matsui should be one of your OF, with Sexson as DH, and Giambi, or someone like him as your 1B.
Also, is Huston Street available as a pick up? He would be a great reliever to snag.
I would have taken the Piazza trade for Konerko personally.
Is Chris Shelton available at C in your league? If he is, grab him.
