Kelvin Herrera RP KC 11 Months
Kelvin Herrera earned his first save of the season Sunday in the Royals' defeat of the Phillies.
Herrera entered the game to clean up a mess that closer Greg Holland helped create, which suggests that there may be a ninth-inning controversy brewing in Kansas City. Herrera has one of the hardest fastballs in the sport and posted an excellent 2.35 ERA, 1.19 WHIP and 77/21 K/BB ratio across 84 1/3 innings last season. He can be an elite closer right now.
