A reader named Sam asks:
With so many contenders in need of relief help (Dodgers, Yankees, Phillies to name three), who do you think are the best relievers that could get traded this summer?
The Orioles may eventually be willing to move a few veteran relievers, such as Danys Baez and Jamie Walker. The D'Backs would probably like to unload Jon Rauch, and could conceivably make Tom Gordon or even Chad Qualls available. The Rays may be able to spare an arm, perhaps Dan Wheeler. The Red Sox have a deep bullpen.
As far as marquee closers go, Jose Valverde could be the best available in July. He's an impending free agent, but on the other hand the Astros are typically loath to throw in the towel. If the Astros do become sellers, they also have LaTroy Hawkins and Doug Brocail.
Other possibilities: Russ Springer, John Grabow, Rafael Betancourt, Huston Street, and Joe Beimel. All of the names in this post are speculative, of course. Your thoughts and predictions?
