UPDATE: According to Alden Gonzalez of MLB.com, Herrera left the game with right forearm tightness. That’s not a good sign.
11:22 p.m. ET: Royals reliever Kelvin Herrera was just forced to exit Game 1 of the ALDS against the Angels with an apparent injury.
Jason Vargas allowed two runs over six innings before being replaced by Herrera, who issued a leadoff walk to David Freese before being visited by a team trainer and exiting the game. It looked like the was shaking out his arm after a pitch on the replay, but we should know more about his status after the game.
It would be a really tough blow if the Royals have to make due without Herrera the rest of the way. The 24-year-old right-hander had a 1.41 ERA over 70 appearances during the regular season.
