Carlos Zambrano might well be off his rocker, but the newest Miami Marlins pitcher also can be a tremendous teammate. He has never been afraid to protect and speak up for his teammates, even sometimes throwing at opponents to ensure his batters are protected. He's passionate, determined and loyal.
That counts for something in MLB clubhouses. As teams choose the lesser players who will make their Opening Day rosters and line up their clubs, they take into account not only talent and skill, but what intangible roles a player might fill for them.
These players should carry extra favor with their teams, then, because each is the best on-field enforcer on his roster, be it dropping sidearm when turning double plays; railroading catchers at home plate; or springing off the bench when a brouhaha breaks out.
