The Tigers have shipped minor league infielder Jack Hannahan to Oakland for Jason Perry, an outfielder who has spent the entire season in Triple-A Sacramento.
Hannahan is expected to join Oakland's big-league roster and fly to the West Coast with the A's after the series between Detroit and Oakland concludes tonight at Comerica Park.
Perry, who will turn 27 this week, has batted .268 with 18 home runs and 58 RBIs in 78 games at Triple-A Sacramento this season. Perry, a left-handed hitter, has fared much better this year against right-handers (.288) than left-handers (.208).
Perry is an adequate defender with some power who will add depth at Triple-A. He's not expected to play in the majors for Detroit this season, but could receive an invitation to big-league spring training in 2008.
