Reported by Jerry Crasnick and Danny Knobler. A reliever may be headed to Detroit as well, and Charlie Furbush is one of the players who could be coming back. If this is true, I ask Z to please do something to make me not hate this trade.
Edit: It's official, per Heyman. No mention yet of who's coming back, but Pauley may be gone too.
Edit 2: So far, it's Fister and Pauley for Casper Wells, Charlie Furbush, and AA 3B Francisco Martinez. Larry Stone says there could still be a "significant name" headed to the Mariners.
