Of course they are.
The Oakland A's spent the first part of the offseason trading away their young pitchers. They spend the second part of the offseason acquiring all sorts of veterans. So which one was it -- rebuild or stopgap? Well, you can't spell "rebuild" without "holy hell what do you want with Manny Ramirez?", so that's the way they're going. From ESPN Deportes:
Oakland interesa a Manny Ramírez
You can go to translate.google.com if you need to, but it means what you think it means. And in no way is this surprising. If you take away all of the baggage and nonsense, Ramirez is very much like Frank Thomas, who resurrected his career in Oakland after injury-plagued final seasons in Chicago.
But saying "take away all of the baggage and nonsense" is like saying "if you remove all of the words and pages, Ulysses is a quick read." It's Manny Ramirez.
Things are likely complicated by Ramirez's need to serve out his suspension for banned substances, which was why he retired in the first place. He'll miss the first couple of months in the season no matter where he goes.
