Kelvin Herrera throws hard, but not criminally so

You might have been made aware that the first head of the Royals' three-headed bullpen monster, Kelvin Herrera, throws hard. He throws hard enough, that it might not seem fair. That's what ESPN's Jayson Stark thought, anyway.

Eight fastballs for Herrera in that inning. Your MPH readings: 101, 100, 101, 101, 101, 100, 101, 100. Call the cops. #worldseries

@jaysonst I'm sorry but there is nothing we can do. He's just throwing a baseball.
