"One possibility could be to consider Derek Lowe, who's being made available by the Braves. The Angels could consider trading Juan Rivera to the Braves for Lowe, then think about signing Bay to replace Rivera"
Seems like a good get for the Los Angeles Angels. I don't think either player's fantasy value would change much.
Rivera would remain a solid value pick, and Lowe would still have to deal with the doubts about his ability to rebound effectively from a disappointing 2009 season.
