More than any other time in recent memory, Major League Baseball is inundated with young budding superstars. Mike Trout has established himself as the best of these young studs, but Manny Machado and Bryce Harper aren't far behind.
I use 22 as the cutoff since that is the age the majority of college seniors graduate and enter the workforce on a full-time basis. It's quite amazing that several players in baseball have already established themselves as big-time players when many others their age are just graduating college. (Note: To make this list, players cannot have celebrated their 23rd birthday yet.)
To compile this list, I took into account not only what each player has done to date, but also the potential they offer in the future.
Potential is measured by each player's performance in the major and minor leagues and their overall package of tools or stuff.
