Livan Hernandez (9-10) was pounded for eight runs on eight hits and two walks in just 4 1/3 innings to take the loss.
Nationals outfielder Nyjer Morgan, who found out Friday that he had been suspended eight additional games on top of a previous seven-game suspension after fighting with Marlins pitcher Chris Volstad on Wednesday, went 0-for-4.
Espinosa's homer in his second career game leading off the third gave Washington the early lead, but Pittsburgh answered with three runs in the home half to go ahead for good.
Cedeno led off with a double and moved to third on Duke's sacrifice bunt. Andrew McCutchen followed with a sacrifice fly for a tie game.

Ian Desmond walked and Ryan Zimmerman singled to start the rally. Dunn plated Desmond with a base hit, and Mike Morse drew a walk to load the bases with nobody out, ending Duke's start.
Sean Gallagher came in and got Ivan Rodriguez to ground into a 5-3 double play, scoring a run, and Maxwell and Espinosa followed with an RBI hit apiece to make it a three-run game again.
Wilfredo Ledezma, Chan Ho Park, Brian Burres and Chris Resop combined to pitch a scoreless seventh and eighth, and Joel Hanrahan pitched around a two-out single in the ninth for his third save.
