Bryce Harper, Jonathan Papelbon brawl in dugout

The season has not gone according to plan for the Nationals, and tempers are starting to flare.

Harper hit a soft pop-up, put his head down and jogged to first. This did not make Papelbon happy, and he began shouting at Harper as he returned to the dugout. Never one to shy away from controversy, Harper barked right back and then the two got into it in the dugout. It got ugly.

Harper was taken out of the game and Papelbon was left in, although it sure looked like the pitcher was the instigator.

UPDATE: Alternate angle makes it pretty clear Papelbon was the troublemaker here:
