The Royals may have the best record in the American League, but they’ll have to go through Toronto and the Majors’ highest-scoring offense this weekend. In Thursday’s 7:07 p.m. ET opener, Kansas City will start Danny Duffy, who has logged a 2.15 ERA in six starts since returning from the disabled list. The Blue Jays will counter with Marco Estrada, who has gone 7-6 with a 3.55 ERA in 21 appearances between the bullpen and rotation.
