In recent years Major League Baseball has seen new faces burst onto the scene and become annual members on the All-Star team. Players like David Wright and Joe Mauer have become fan favorites and household names as they've launched careers among the best in baseball.
Other players have seen their personal stars dimmer over the last few seasons. The 10 players whose careers used to shine among brightest in the baseball sky and have since gone the other way are included in the following slides. (Note: Two players who might come to mind for this list that are not included are Justin Verlander and Jeff Francouer. The belief with these two is that neither has even reached his prime yet, and could easily return to their former status as a player).
