From Peter Gammons:

5. Word is the Angels are worried enough about their starting pitching to look around, especially at the Reds. And several Arizona teams have expressed interest in Boston reliever Manny Delcarmen. Boston needs a catcher, and could use another infielder and even another outfielder.

If I were Walt, I'd offer Bronson Arroyo for shortstop Erick Aybar or Brandon Wood. I prefer Aybar. I'd hate to trade Arroyo but if we can land a shortstop of the future then I would have to make the deal.
