Yes, Jason Frasor use to be Dodger property. He was originally drafted by the Tigers, but was sent to us as a 'Player to be Named Later' in a deal that sent Hiram Bocachica to Detroit. As he excelled under the tutelage of the Dodgers farm system, Jason was traded straight up to Toronto for Jason Werth. There, he became a regular middle reliever for a number of years with a few stints as a closer when needed. Jason Werth, on the other hand, never accomplished much with the Dodgers, but proved to be a good pick-up after he left Los Angeles and starred in Philadelphia. Bocachica, on the other hand, never produced the kind of power seen in Albuquerque.
Here is a 2004 Donruss Playoff Absolute Playoff autographed card of Jason Frasor in my collection.
