ATLANTA — Ryan Zimmerman has faced R.A. Dickey enough to know what to expect from his knuckleball.

"I don't want to say it's comfortable because when he's got a good one going it's not easy," he said. "Having faced him a few times before, you at least know what to expect."

Zimmerman hit a two-run homer, Stephen Strasburg struck out 10 and the Washington Nationals completed a three-game sweep with a 3-2 victory over the Atlanta Braves on Thursday night.

A night after they had 14 runs on 20 hits, the Nationals couldn't solve Dickey until Zimmerman homered in the sixth to erase a 2-1 deficit.

Strasburg (2-0) allowed two runs, six hits and two walks in seven innings, winning his first start at SunTrust Park after going 4-3 with a 4.37 ERA in 10 outings at Turner Field. With the win, Strasburg earned his 71st career victory, the most in Nationals history.

Shawn Kelley had an eventful ninth before earning his second save in three tries. He retired the first two batters before Kurt Suzuki singled and pinch-hitter Tyler Flowers walked. Ender Inciarte followed with a game-ending flyout.

Atlanta went 4-3 on its first homestand at its new ballpark, where it opened by sweeping a four-game series from San Diego.

Dickey (1-2) gave up three runs and three hits in seven innings.

Zimmerman, who has hit safely in 12 of 15 games, doubled to begin the second and scored on Michael Taylor's sacrifice fly, then hit his fifth homer.

"A knuckleball is going to do what it does, and I have to own that one to Zimmerman," Dickey said. "It was a bad pitch, but I didn't make many of them tonight. I felt like I could have pitched all night."

Dickey hit an RBI grounder in the second, and Kurt Suzuki had a sacrifice fly in the fourth.

The Nationals have won 18 of the last 22 games in the series and 10 of the last 13 games in Atlanta.

"That's huge to sweep a team on the road, that's a good way to start the road trip," Strasburg said. "Keep it going tomorrow."

WELCOME BACK, NOT REALLY

Matt Kemp came off the 10-day DL and couldn't catch up to Strasburg's fastball, striking out three times. Kemp, who missed eight games with a sore hamstring, grounded out softly to reliever Koda Glover in the eighth.

NICE GLOVES

Washington RF Bryce Harper ran forward to make a shoestring catch to save two runs in the second. ... Taylor ran up and dove to catch Phillips' liner to save a run in the sixth. "Michael made of the game," Nationals manager Dusty Baker said. "If that ball gets by him, that's a triple."... Strasburg got some good defence behind him in the seventh by LF Adam Eaton, who had to adjust his glove wrist up on a running catch, and 3B Anthony Rendon, who was guarding the foul line and dropped to the ground before throwing out Adonis Garcia.

COOLED OFF

Braves 1B Freddie Freeman was leading the majors with a .440 average but went 0 for 4.

TRAINER'S ROOM

Nationals: 2B Daniel Murphy was scratched from the lineup with right leg tightness. Manager Dusty Baker said he could tell Murphy wasn't following through with his swing during Wednesday's 14-4 win. ... Baker said SS Trea Turner, on the 10-day DL since April 10 with a strained right hamstring, will be activated Friday at the New York Mets but likely won't start. ... LF Jayson Werth was held out of the lineup with a sore groin.

Braves: SS Dansby Swanson wasn't injured, but manager Brian Snitker gave him a scheduled night off from the starting lineup. Swanson pinch ran in the ninth.

UP NEXT

Nationals: RHP Tanner Roark (2-0) has a 3.50 ERA in three starts. He is 3-1 with a 2.08 ERA in five starts and three relief appearances at Citi Field, where the Nationals open a series Friday.

Braves: RHP Bartolo Colon (1-1) has a 4.24 ERA in three starts going into Friday's outing at Philadelphia.
