Kelvin Herrera RP KC Jan 16 '79
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.
