Giancarlo Stanton Little League Photo

As his recent Throwback Thursday Instagram photo shows, Marlins slugger Giancarlo Stanton even had swagger as a kid. As he sits with his teammates sporting the "people's eyebrow," the 10-year-old slugger already had the look down. Thirteen years later, Stanton has even more talent, power and of course, swagger, enabling him to become one of the best home run hitters in the game today.
