Doug Fister said he really hadn’t heard about the scoreless innings streak being crafted by his fellow Washington Nationals starters. 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.
