Phillies Rookie Aaron Altherr Hits Inside-the-Park Grand Slam vs. Nationals

Philadelphia Phillies left fielder Aaron Altherr may only be a rookie, but he certainly made a name for himself Friday night against the Washington Nationals. 

During the top of the third inning with the bases loaded, the 24-year-old Altherr hit a liner to center field off pitcher Jordan Zimmermann. Nationals outfielder Michael Taylor attempted to make a highlight-reel diving catch but failed. The ball rolled back to the center field wall, allowing Altherr to clear the bases and book it home. 

We haven't seen anything like this since 1999.

Altherr also hit a solo home run in the fifth inning. The Phillies went on to win, 8-2.
