Carlos Narváez put Boston ahead with a three-run homer against his former team in the sixth inning, and the Red Sox overcame two home runs by Aaron Judge in an 11-7 victory over the New York Yankees on Sunday night.
Rafael Devers also went deep as Boston equaled a season high with five longballs to take two of three games at Yankee Stadium in the first series this season between the longtime rivals.
Narváez signed with the Yankees in 2015 and broke into the big leagues with them last year, getting into six games before New York traded him to Boston in December.
