Major League Baseball players rarely play their entire career with the same team, even the best of the best.

In this edition of Reading Baseball, Pete Peterson takes a look at how fans often have their hearts broken when their favorite players end up on a different team.

Reading Baseball is a series of essays and commentaries by Richard "Pete" Peterson, co-author, with his son, Stephen, of  The Slide: Leyland, Bonds and the Star-Crossed Pittsburgh Pirates and the editor of  The St. Louis Baseball Reader.
