If an ounce of prevention really is worth a pound of cure, it figures that the Cubs and other teams would be willing to invest heavily in technology that can help them keep their players on the field.

One example of this tech in action is on the right arm of Jose Albertos, whose young career is only now getting back underway a year after it stalled right out of the gate.
