This is actually good news, since the price on Soria is apparently astronomical. The Phils don't need him, and I'd prefer they not be tempted to pursue him. Soria is a great talent, but he's not worth the "exorbitant" return KC would want. Certainly not for the Phillies.
In that sense, it's kind of a non-story, but I mention it because I'm kind of surprised a player would specifically mention not wanting to play for big-market contenders like Philadelphia, Boston, and New York, or even a small market contender like Atlanta. Maybe he just doesn't want to relocate, so he's listing the teams most likely to deal for him?
