Andruw Monasterio hit a grand slam as part of a 10-run ninth inning and the Boston Red Sox snapped a four-game skid with a 17-1 victory over the Baltimore Orioles on Saturday. Willson Contreras added a three-run homer and Caleb Durbin a two-run shot in the Boston ninth against Orioles outfielder Weston Wilson, after Monasterio's drive had helped to chase reliever Keegan Akin in his season debut.
