Before the Washington Nationals faced the San Francisco Giants in game 2 of the National League Division Series Saturday, one military veteran had the honor of throwing the first ceremonial pitch – which isn’t as unusual as the way he tossed the ball.

Retired Sgt. 1st Class Brian Keaton belly crawled to the mound before making sure all was clear to toss the ball with his left hand from behind the mound like a grenade to Nationals pitcher Doug Fister.

According to the Nationals, Keaton served in Iraq and was injured in a bomb explosion and spent 3 1/2 years recovering at Walter Reed National Military Medical Center. 

Keaton was cheered on and embraced with bear hugs from the team before leaving the field. Needless to say, this will be one memorable moment in Nats history!
