Jayson Werth calls Nationals' closer Jonathan Papelbon "The D.C. Strangler"...

Just when you thought a ninth-inning home run off Jonathan Papelbon would keep the Washington Nationals from a three-game sweep of the Philadelphia Phillies, Jayson Werth came through with a walk-off single.

Just when you thought Papelbon would never get a better nickname than "Johnny Jonathan", Jayson Werth dubbed him the D.C. Strangler in his postgame interview with a stunned/flummoxed MASN reporter Dan Kolko.

Werth got mobbed by his teammates after his walk-off winner and Kolko innocently asked the 37-year-old outfielder about the experience of getting "beat up" after hitting the single that beat the Phillies.

"You got battered out there. What type of damage did they do to you in the outfield?" Kolko asked.

"Well, I knew I was in trouble when I saw 'The Strangler' coming at me," Werth said.

"Who's 'The Strangler'?" Kolko asked, perhaps naively.

"You know, the D.C. Strangler," Werth said, referring, of course, to Papelbon, whose dugout choking of Bryce Harper last season made headlines around the baseball world.

"We'll move off that," Kolko said.

Werth just laughed an evil laugh and moved on with the interview, knowing that he'd likely just set Twitter and social media world aflame.

If you somehow missed it. Here's Werth coining the latest catchphrase to sweep the nation's capital:
