There were some tremors rocking through Nationals Park on Sunday courtesy of a Werthquake.
Nationals slugger Jayson Werth launched a 437-foot pinch-hit grand slam in the seventh inning against the St. Louis Cardinals.
The Nationals' bench was lifted to its feet as the long-haired outfielder trotted the bases, helping his club wallop the Cardinals 10-2.
