Christian Vazquez's RBI double and Rafael Devers' three-run homer put the Red Sox back in the lead.
So it was the perfect place for Devers' homer drought -- which dated back to Aug. 19 -- to end.
Rick Porcello struggled, lasting only 4 innings and giving up four runs, four hits and three walks while striking out three.
The lefty -- making his second relief appearance since returning from the DL -- hurled 2 2/3 scoreless innings.
He struck out Scooter Gennett, the final hitter he faced, on a 95.2 mph fastball.
