According to rotoworld:
"Padres non-tendered catcher Miguel Olivo.
The Padres' official site reported that the team had kept Olivo and dropped David Ross. Something changed. Obviously, Olivo wanted quite a bit more money than Ross did. The Marlins or another team looking for a young catcher will pick him up."
Guess we'll never get to see if he can substain his "success" in San Diego.
