Marcelo Mayer’s opposite-field RBI double cut Boston’s deficit to 3-2. It left his bat at 108.7 mph. Ceddanne Rafaela then connected on a 1-2 slider outside of the zone and dropped it into center field for a go-ahead two-run double to make it 4-3 Red Sox.

The Red Sox will be without one of their touted rookies Friday, and perhaps for their entire weekend series against Toronto at Fenway Park.

Boston Red Sox manager Alex Cora told the media pregame that rookie infielder Marcelo Mayer is a “stud” defensively, and that the 22-year-old could probably play first base if the team asked him to.
