The Toronto Blue Jays flexed their muscles last season in leading the majors in homers en route to the AL East crown.
The Baltimore Orioles are currently setting the pace for longballs in the AL as well as the East lead.
These power-hitting teams meet for the first time in Tuesday night's three-game series opener in which the Orioles try to improve to 6-0 at home.
Toronto (7-7) drilled 232 homers last year, with Baltimore third at 217. The Orioles (8-3) have gone deep 23 times to lead the league, with five apiece by Mark Trumbo and Chris Davis.
