Bryce Harper walked three times against Lynn to reach base in nine straight plate appearances going back to Monday, tying a career high set last season against the Chicago Cubs and manager Joe Maddon. He also doubled in the eighth.
Lynn hadn't allowed a hit when he walked Gonzalez on four pitches with one out in the third. After a fielding error and a walk to Harper loaded the bases, Murphy ripped a two out-single through the infield to give Washington a 2-1 lead.
Grichuk's homer tied it in the top of the fourth before Werth and Wieters went deep in the bottom of the inning. Then in the fifth, Lynn walked Harper for the third time before Murphy blasted a 1-2 changeup into the second deck in right to make it 6-2.
Murphy drove in Harper for a second time on an RBI double in the eighth.

DENVER (AP) -- Trea Turner has hit for the third cycle in Washington Nationals history against the Colorado Rockies on Tuesday night.
Turner also has a career-high seven RBIs on a cold night in the Mile High City.
He had a single in the first, a two-run double in the second, a two-run homer in the sixth and a bases-loaded triple in the seventh.

The field temperature was a balmy 37 degrees when Turner recorded the final part of his cycle in the seventh inning.
It was the first cycle by the Nationals since Cristian Guzman on Aug. 28, 2008.
Overall, this was the ninth cycle in Expos/Nationals history.
In addition, Turner's seven RBIs are tied for the second-most in a single game in Nationals history.
The Nationals hung on to beat the Rockies 15-12 after giving up seven runs in the final three innings.
If you've understandably been caught up with the Capitals and Wizards in their respective playoff series, you might not be aware of just how hot Nationals right fielder Bryce Harper is right now. Fresh off a three-game sweep of the rival Mets in New York, Harper was named National League Player of the Week.
For the whole week, Harper hit .550 (11-for-20) with four doubles, three home runs, seven RBI, seven walks and 10 runs scored.
He is now leading all of baseball in batting average (.400), he's tied for second in homers (7), and he's alone in second in RBI (20). He's also amassed a blistering 1.340 OPS through the team's first 18 games.
Harper's biggest game of the past week came in Atlanta when he went yard twice, with his second homer being a grand slam. He finished the game 4-for-4 with two homers, one double, five RBI, one walk and four runs scored.
With Harper's injuries from last season behind him (even though he won't completely admit to being hurt), the Nationals' right fielder is back to, or even better than, his 2015 form that ended with his first career MVP award. During that season Harper took home player of the week honors three times.
The Nationals as a team have the best record in baseball at 13-5, and already have a three-game lead in the NL East.
