Baseball fans and players are known to be superstitious but would you want your favorite team to house a wild Opossum as a good luck charm? The Oakland A's are doing just that and as long as the little guy(or girl) doesn't have to many babies it's going to stay.
Reps for the team tell TMZ Sports, "We're undefeated since he showed up, and have no intention of getting rid of him."  The rep says they won't call Animal Control on RP ... unless it starts procreating like crazy.
