Royals manager Ned Yost said Yordano Ventura, who was scheduled to pitch on Saturday, will make the start on Sunday.
"We'll stay in the rotation, just push everyone back a day," Yost said.
That means right-hander Jeremy Guthrie will make the start on Tuesday in the series opener against the Indians at Kauffman Stadium.
