WASHINGTON (AP) -- Doug Fister allowed four hits over seven innings in another superb outing by a Washington starter, and the Nationals defeated the Atlanta Braves 7-0 on Thursday for their sixth straight win.Washington's rotation has thrown a franchise-record 41 1-3 consecutive scoreless innings over its last six games, the longest streak in the major leagues since Cleveland starters strung together 44 1-3 shutout innings in May 2008.And next up is Max Scherzer, who starts Friday at Philadelphia. Scherzer struck out 16 in a one-hit shutout at Milwaukee on June 14, then pitched a no-hitter against Pittsburgh last Saturday, when he had a perfect game until he hit a batter with two outs in the ninth. Fister (3-3) made his second start since a stint on the disabled list caused by right forearm tightness. He struck out four and walked one, and Blake Treinen finished the Nationals' eighth shutout with a two-hit ninth.Washington has won eight straight games against the Braves. Every Nationals batter had at least one hit.Braves right fielder Nick Markakis' streak of 398 games with an error, a record for non-pitchers, ended when he bobbled Denard Span's first-inning single.Matt Wisler (1-1), who won his major league debut last week against the New York Mets, allowed six runs - four earned - and nine hits in four innings.Cameron Maybin and Kelly Johnson had two hits each for Atlanta, which has scored 13 runs in its last seven games.Braves miscues played a role in each of Washington's rallies.
