Yost not afraid to use rookie Finnegan in key spot

Royals starter Danny Duffy, just back from an injury, was finished after six shutout innings. There was a 2-0 lead over the Indians on Monday night, and the seventh inning usually belongs to reliever Kelvin Herrera, who had been worked hard of late. So what’s a manager to do? Why, call in rookie left-hander Brandon Finnegan, with all of 4 1/3 innings on his Major League resume.
