BALTIMORE -- Manny Machado lit up the scoreboard all night and Matt Wieters contributed a late three-run homer to help the Orioles slug their way past the Nationals, 10-8, at Nationals Park on Wednesday night. Both Wieters and Machado -- who finished with four hits, including his 29th homer -- drove in four runs in support of left-handed starter Wade Miley, who was acquired by Baltimore last month and earned his first win as an Oriole with five-plus innings of two-run ball.
The win was the Orioles' third straight over the Nationals and came hours after the team placed ace Chris Tillman on the disabled list.
"Right now, this time of the year, it may be important for us because we're thin … right now, and we need all of our healthy pitchers to do what they're capable of doing," Orioles manager Buck Showalter said. "There's not much margin for error as we go forward here with 30-some games left."
The Nationals fell short despite the continued dominance of rookie center fielder Trea Turner, who followed up Tuesday's 4-for-4 performance with a hit in each of his first four at-bats on Wednesday, tying a franchise record shared by Andre Dawson and Dmitri Young by recording a hit in eight consecutive plate appearances.
Turner, who also robbed Adam Jones of extra bases with a diving catch in the right-center-field gap on the first play of the game, struck out to end his run in the ninth inning.
"It was a quick one -- warmed up and went right into the game," Britton said. "Not ideal, but we had a cushion, so if there was any day to not be your best, it was today."
Said Zimmerman: "I got a ball and put a good swing on it. Unfortunately, I hit it right at [Jonathan] Schoop. It was the first pitch. It's unfortunate."
Typically a reliable workhorse, Nationals starter Tanner Roark was off from the start, hit hard for five runs (four earned) on seven hits over five innings to take the loss. Roark had little command in the first two innings, when he threw 62 pitches, allowed the five runs and hit three batters.
"I couldn't locate; it was as simple as that," Roark said. "I was trying to go inside to get them off the plate and make them feel uncomfortable. That's how I pitch. Obviously not my best outing. What I love is that we came back and came pretty darn close to tying it up or possibly winning it."
Baltimore, which holds the second American League Wild Card spot, also gained a game on a pair of AL East rivals, as both the Red Sox and Blue Jays, who are tied atop the division, lost on Wednesday.
MOMENTS THAT MATTERED Starting strong: Baltimore had a four-run lead before Miley and the defense even took the field. After Turner's stellar catch in center field, six straight Orioles hitters reached base. The first two runs scored on Machado's homer to left field, which was projected to land 452 feet from the plate by Statcast™. From there, a double, walk, two hit-by-pitches and a sacrifice fly brought home two more. Despite Washington's late push, Baltimore held its lead for the rest of the game.
"We had a lot of good at-bats early before Roark could really get his feet on the ground," Showalter said. "He's having a big year for them, so you try not to let him settle in."
Machado said he was surprised to see Roark struggle but glad the Orioles could capitalize.
"We took advantage of his mistakes," the third baseman said. "He doesn't really hit many guys, and he throws a lot of strikes. We just took advantage of the situation."
Many missed chances: In the sixth inning, with Baltimore leading by three runs and Miley running out of steam, the Nationals had runners on second and third with no outs. Reliever Mychal Givens entered and extinguished the Nationals' rally. Anthony Rendon struck out, Wilson Ramos popped out to Schoop at second base and Zimmerman struck out to end the frame.
"[Givens] threw sidearm at 97 [mph]," Zimmerman said. "I don't know where they get them from."
Wieters delivers: After the Nationals got a run back in the seventh to cut the Orioles' lead to two runs, Baltimore answered in a big way with five runs in the eighth. Facing sinkerballer Blake Treinen, Wieters didn't wait long to push the O's into double digits in runs, driving the first pitch of the at-bat 416 feet to center field for a three-run homer that widened Baltimore's lead to seven runs. The homer was especially vital given the Nationals' ninth-inning rally.
"You always want to try to add on, especially against a good offense like they have," Wieters said.
Turner burner: Turner, who hit three singles and a double in Tuesday night's loss at Camden Yards, rapped four singles on Wednesday to lift his slash line on the year to .335/.359/.544. The rookie was humbled to place his name in the franchise's record books after just 64 big league games.
"It's always nice to have your name associated with other great players and a record," Turner said. "It's something that I'll remember. I'm not shooting for it, but I'll take eight straight hits any day of the week.
"I think it's an empty mind. You're not really thinking too much. You just react. I think the more you can do that, the better you'll be, the more success you'll have. Better pitches you'll swing at." More >
"We were better than [the Orioles] in hits, but they got some key two-out base hits. That was the difference in the game. Manny Machado was a handful today, too. Right away -- boom -- he gave them a 2-0 lead. It was kind of Machado vs. Murphy tonight." -- Nationals manager Dusty Baker

WHAT'S NEXT Orioles: The four-game home-and-home Battle of the Beltways set concludes on Thursday night at 7:05 ET at Nationals Park. Veteran righty Ubaldo Jimenez (5-10, 6.94 ERA) will take the hill for Baltimore, making his first start in nearly a month. Jimenez is filling in for Tillman, who was placed on the disabled list on Wednesday with right shoulder bursitis.
Nationals: Right-hander Max Scherzer, who is 4-2 with a 3.81 ERA in eight career starts against the Orioles, will oppose Jimenez. Washington's ace is also 9-6 with a 2.75 ERA in Interleague games when pitching at home over the course of his career.
