Bryce Harper is the First Teenager Since Ken Griffey Jr to Hit a Home Run

Bryce Harper wasn't even born when Ken Griffey Jr. hit a home run in the Major Leagues in 1989.

Griffey, who later played for the Reds, hit a home run off Eric King of the Chicago White Sox on April 10, 1989.

Harper connected off Tim Stauffer from the San Diego Padres in the third inning in the Nationals 8-5 win.
