The Royals are a game and a half out of the crazy AL Wild Card race — six games back of the Indians in the division — so they don’t have a huge margin for error. They got some bad news last night, though, that could have a major impact on their playoff hopes: closer Kelvin Herrera experienced tightness in his right forearm in the ninth inning of last night’s win, forcing him out of the game.
Herrera walked the bases loaded, then went to a 2-0 count on the next batter before leaving the game. That last pitch was a fastball that clocked in at 91 m.p.h., which is NOT a typical Kelvin Herrera fastball. Herrera didn’t talk after the game but his teammate Sal Perez said that Herrera told him “I’m tight. I don’t feel my forearm.”
Reporters left the clubhouse before an official diagnosis or prognosis could be delivered, so expect an update some time today. If Herrera is out the closer duties could fall to Scott Alexander or Brandon Maurer.
