Mike Moustakas hit his 37th home run of the season, breaking Steve Balboni's Royals record, Salvador Perez and Whit Merrifield also connected and Kansas City routed the Toronto Blue Jays 15-5 on Wednesday night.
Rookie right-hander Jakob Junis (8-2) allowed four runs, two earned, in 6 1/3 innings, improving to 5-0 with a 2.42 ERA over his past eight starts.
Moustakas went 3 for 4 and came within a triple of hitting for the cycle. He eclipsed Balboni's 1985 record with a solo blast to right off Carlos Ramirez in the sixth.
Merrifield also had three hits and drove in a pair of runs as the Royals snapped a three-game losing streak and won for the second time in their past seven.
Kansas City came within a run of matching its season high. The Royals scored 16 against Detroit twice within a seven-day span in late July.
