After Danny Espinosa struck out, Kurt Suzuki walked to load the bases. Cishek got pinch-hitter Roger Bernadina to strike out on three pitches before striking out Jayson Werth swinging on a slider outside of the strike zone.
"To be honest, that's the first time I ever remember managing a baseball game and you win and you don't know what to say," Marlins manager Ozzie Guillen said. "Very confusing. Good battle. They battled back, they never quit, they never gave up."
The Marlins had a solid chance at winning the game in the ninth after putting runners on first and third. But with one out, catcher Rob Brantly lined out to Bryce Harper, who one-hopped his throw from short center field to Suzuki to nab Greg Dobbs at home.
In front of 28,533 fans, Turner far surpassed Strasburg's poor outing with a six-inning effort, allowing only two runs on four hits. Strasburg, meanwhile, lasted only three innings and surrendered five runs on six hits while adding two strikeouts and three walks.
"I thought he looked pretty solid," Brantly said of the rookie Turner. "He battled all the way through tonight, every inning he pitched. You could see even in hitter's counts, he wasn't giving in and still mixing in his offspeed pitches really well."
Guillen said after the game that Turner was on a pitch count between 80 and 85 pitches, and any further pitch count on the 21-year-old rookie this season will be a front-office decision.
"Even if I was [on a pitch count], that's not something you would want to worry about," Turner said. "I felt like I got stronger as the game went on. Obviously the first inning was a little rough, but I made pitches when I needed to in the later innings."
The Marlins led 6-2 entering the seventh, when Carlos Zambrano came in for Turner. Zambrano gave up a single and a pair of doubles, allowing the Nats to draw within 6-4.
After a Suzuki double, Ryan Webb entered for Zambrano and surrendered an infield single to pinch-hitter Steve Lombardozzi. Suzuki scored on the play, charging Zambrano with a third run. Zambrano allowed three runs on three hits, all without recording an out. Webb retired Werth on a forceout before Mike Dunn entered to get the final two outs.
"Carlos got a little cut in his finger right before he was in the bullpen," Guillen said. "He told me he felt good. I don't think it was his finger. I just think he didn't have anything and he got whooped pretty good."
Michael Morse brought the Nats all the way back in the eighth with a solo shot to straightaway center that tied the game at 6.
The Marlins scored runs in each of the first four innings, beginning with two in the first on a Giancarlo Stanton double and a Lee sacrifice fly.
The Nats responded with a pair of runs in the bottom of the frame on a Ryan Zimmerman home run to left field.
In the second, Brantly sent the first pitch he saw from Strasburg, a 96-mph fastball, over the right-field wall to give the Marlins a 3-2 lead. The homer was the second of Brantly's rookie season. The 23-year-old catcher entered the game 10-for-29 (.345) over his last nine games.
"I didn't command the fastball, I kept getting behind in the count," Strasburg said. "I kept falling behind. I wasn't able to use other pitches effectively. They teed off on me a little bit."
After Reyes flied out to lead off the third, Stanton ripped a 97-mph Strasburg fastball to right-center for his 31st homer. Stanton finished 2-for-5 with two RBIs. Two batters later, Dobbs hit a ground-rule double down the left-field line. Dobbs scored on a single from Donovan Solano in the next at-bat.
The Marlins tacked on another run in the fourth, after Justin Ruggiano walked and then scored on a Reyes triple. Reyes finished 3-for-6 with three RBIs.
Miami had a chance at more runs in the eighth after a double by pinch-hitter Austin Kearns and a single by Ruggiano two batters later, but both runners were stranded.
