New York Yankees rookie Aaron Judge is off to a historic, prodigious start at the plate, hitting the most home runs for any rookie through 25 games (13) and drilling 10 homers in his last 14 games. His Bunyanesque shots are only adding to his mystique and should he keep it up over the next few games, Judge will turn into a full-fledged national star. In doing so, the 25-year-old would join a short list of athletes who burst onto the scene like a supernova and became instant phenoms. He should be careful though: As this list shows, supernovas tend to burn out quickly and without much warning.
