To clarify, no bodily harm will come to these MLB players who are ready to "explode." Rather, this list analyzes breakout candidates who should provide much more value in 2013 than they have in previous seasons.
As you would expect, all of the following are young and relatively inexperienced—under 30 years old with less than four years of major league service time.
An individual can't truly explode if he has produced at an MVP-caliber level before. That's why Giancarlo Stanton and Mike Trout, for example, have been excluded. Though neither has peaked, the viewing public is already in awe of their brilliance.
From a fantasy baseball perspective, these difference-makers should be drafted early. Their stats will certainly improve from the previous summer.
Understandably, opposing players want to keep their distance from these emerging phenoms.
