WASHINGTON -- Atlanta right fielder Nick Markakis saw his record streak of 398 consecutive games without an error end in the first inning of Thursday's 7-0 loss to the Washington Nationals. It was one of the the Braves committed in the loss.
Denard Span singled to right field leading off, and Markakis bobbled the ball, allowing Span to take second.
Markakis, who signed with Atlanta in the offseason, established the MLB record for consecutive errorless games by a non-pitcher on June 18 -- breaking the previous mark of 392, set by Darren Lewis from 1990 to 1994.
Markakis had not made an error since Aug. 10, 2012, while with the Orioles.
"We weren't real pretty to watch today," Braves manager Fredi Gonzalez said. "Let's just put it that way."
Kelly Johnson said the streak hadn't changed the way Markakis plays.
"Nick still runs in, charges balls, he still comes in, gets around balls, and tries to get, tries to make the right plays. He's not laying back," Johnson said.
Markakis' error was the beginning of a theme, with Braves miscues playing a role in each of Washington's rallies against rookie starter Matt Wisler, who allowed six runs -- four earned -- over four innings.
"We put him in situations where he was always in trouble and never gave him a clean inning and an opportunity to get out of a jam," Gonzalez said.
Markakis' error allowed Span to take second, before he reached third on a sacrifice and scored on Yunel Escobar's ground out.
In the second, Ian Desmond grounded to Kelly Johnson at third, whose throw to first sailed out of play, allowing Wilson Ramos to score from second. Desmond later scored on Michael A. Taylor's double to make it 3-0.
Then Desmond blasted a two-run homer in the third to make it 6-0 immediately following Pedro Ciriaco's off-target relay throw, one which could've nabbed Ramos for an inning-ending double play.
"I was supposed to go down and away," Wisler said of the home run pitch. "I just left it up. I just made some bad pitches today."
Peterson's throwing error in the eighth allowed Taylor to reach second base and then score on Matt den Dekker's two-out single.
Doug Fister allowed four hits over seven innings in another superb outing by a Washington starter as the NL East-leading Nationals completed a series sweep. Atlanta fell five games behind the Nationals and 1½ behind the New York Mets.
