PHILADELPHIA — Freddie Freeman homered twice and drove in four runs and Nick Markakis also hit a home run to lead the Atlanta Braves to a 7-1 victory over the Philadelphia Phillies on Friday night. It was a rare power surge for the Braves, who entered last in the majors by a wide margin with just 15 homers. Philadelphia’s 31 homers entering Friday were second from the bottom in the big leagues.
