The injuries haven't stopped Perez from producing, but he is admittedly banged up. He was able to pick off his fifth runner of the season on Thursday and threw out his 14th would-be base-stealer on Wednesday, so his play has not slipped.
Brayan Pena started at catcher on Friday and will more than likely do it again on Saturday in Perez's place. Adam Moore will take his spot behind the plate on Sunday, prior to Perez's return on Monday.
Perez joins left fielder Alex Gordon as two Royals out with injuries. Gordon hurt himself while sliding in the sixth inning of Thursday's game against the Chicago White Sox.
