How did Brian Dozier get pumped up for the Nationals game against the Marlins on Thursday??
TWERK! TWERK! TWERK! TWERK!
The Washington second baseman was clearly feeling a little frisky in Miami before the final game of the Nats-Marlins series ... so he decided to back that thang up on a Nats staffer!!
Unclear why ... but the video is hilarious -- Dozier does a secret handshake and dance with Victor Robles, then turns his hat backwards and decides to twerk it out!!
The best part? Washington's staffer plays along ... and slaps a big ole' handful of booty!
