The Royals announced Chris Young as the starter for Saturday's Game 4, while Edinson Volquez is slated to start Game 5 on Sunday.
Young threw 53 pitches over three scoreless innings to earn the win in Game 1, pitching the 12th through the 14th. He'll be going on three days' rest in Game 4, but Yost was not concerned about the 36-year-old being ready for his start.
"Our plan for Chris Young was that if we needed him we would use him 45 to 50 pitches and he would still be available in Game 4," Yost said.
