Atlanta Braves outfielder Nick Markakis made an error during the first inning of Thursday's game against the Washington Nationals, ending his record-setting streak of 398 consecutive games in the outfield without making an error, per ESPN Stats & Info.
The miscue allowed Nationals outfielder Denard Span to advance to second base on a leadoff single and later led to an unearned run on a groundout by Nationals infielder Yunel Escobar.
Markakis' previous error came back on Aug. 10, 2012, while he was playing for the Baltimore Orioles. He recently set an MLB record for an outfielder when he made it to 393 straight games without an error, breaking the old mark of 392 set by Darren Lewis to start his career between 1990 and 1994, per Ian Denomme of Yahoo!
