According to the Buffalo News. Haven't seen this anywhere else:
Third baseman Aaron Herr, the Buffalo Bisons' leader in games played, home runs and RBIs, was traded today by the parent Cleveland Indians to the Cincinnati Reds for cash considerations.
Herr, 27, was batting .245 for Buffalo with nine homers and 32 RBIs in 65 games. But he became expendable when the Tribe signed former National League all-star Morgan Ensberg as a minor-league free agent last week. Herr had not played for the Herd since Ensberg arrived.
