Ceddanne Rafaela followed with a two-run double that scored Anthony and Story to make it 3-0, and then Duran singled to drive in Rafaela with Boston’s fourth run.

The Red Sox increased their lead to 10-0 in the seventh. After Marcelo Mayer singled against Jake Bird with one out, Gonzalez hit an RBI triple. It was 6-0 after Anthony singled to drive in Gonzalez.

Story’s home run extended the lead to 9-0, and Duran’s 456-foot home run against Zach Agnos capped Boston’s scoring.
