Per Rotoworld:
Me thinks the Reds are holding onto Patterson should Griffey be traded. That and Hatteberg doesn't have much impact on the bench, Valentin can play a similar role as a replacement 1B and has more position value to the coaching staff as a catcher.The Cincinnati Enquirer reports that the Reds may designate Scott Hatteberg for assignment Tuesday to make room on the roster for Jay Bruce.
Hatteberg lost his starting job to Joey Votto and has complained about pinch-hitting duties, but he's still among the team's better hitters.
Patterson would be useful as a late-inning replacement for the defense, but you have to wonder if he was kept due to being more valuable (in the eyes of the front office) or because he is one of Dusty's guys (that and the fat contract.)
