PITTSBURGH (AP) — Whit Merrifield had four RBIs, three on his first homer of the season, and the Toronto Blue Jays routed Pittsburgh 10-1 for a three-game sweep that extended the Pirates’ losing streak to seven. Merrifield put the Blue Jays ahead with a run-scoring infield single in the first following a 95-minute rain delay and opened a 4-0 lead in the third when he sent a hanging curveball from Roansy Contreras into the left-field bleachers. Toronto outscored Pittsburgh 22-3 during the sweep, bouncing back from five straight losses.
