Ryan Zimmerman's two-run home run in the 16th inning lifted the Washington Nationals to a 4-2 victory over the Milwaukee Brewers on Tuesday night.

Zimmerman hit a 2-0 pitch off Mike Fiers (0-1) over the wall in left field to score Adam LaRoche for the Nationals fourth consecutive win.

Tyler Clippard (5-2) pitched a scoreless 15th for the win. Rafael Soriano pitched the 16th for his 18th save.

With one out in the 16th, LaRoche hit a sharp single that bounced off the wall in right field. Zimmerman then hit his third home run of the year to give the Nationals the lead in a game that took 5 hours, 22 minutes.

The Brewers threatened in the 13th, 14th and 15th innings, but couldn't score. Lyle Overbay was stranded on third base in the 13th when Carlos Gomez hit a soft liner to shortstop to end the inning.

In the 14th, Denard Span kept the Nationals alive with a leaping catch at the wall to rob Elian Herrera of an extra-base hit that likely would have scored Khris Davis from first and won the game for Milwaukee.

Gomez popped out to end the 15th with Scooter Gennnett on second.
