Rookie Michael Chavis hit a grand slam, Xander Bogaerts had three hits and Andrew Benintendi drove in three runs to lead the Boston Red Sox to a 10-8 victory over the Toronto Blue Jays.
Boston batted around for five runs in the first inning against starter Trent Thornton (3-7) and then sent 10 batters to the plate in the third, scoring five more during Monday's MLB game.
Rick Porcello (7-7) gave up four runs and eight hits in six innings, striking out two. Brandon Workman pitched the ninth for his fourth save.
Four of the first five batters reached safely against Thornton before Chavis hit a 3-2 pitch 421 feet over the Green Monster in left-centre to make it 5-0.
Thornton, who threw six shutout innings in his previous start, allowed five runs on five hits and three walks while getting just four outs for Toronto, which has lost six of eight.
