Orlando had been sent out to make room for Ben Zobrist on the last road trip.
"When we sent Orlando out, our plan was probably to give it about 15 days and then swap him for Cheslor to keep them both fresh and playing [in the Minors]," Yost said. "Then we wanted to get them back for September. Just didn't want them to get stale."
• Yost was adamant that right-hander Jeremy Guthrie, who gave up six runs on Saturday, will stick in the rotation.
"Yes. He won the game," Yost said.
Guthrie's ERA rose to an unsightly 5.84.
"I don't like that ERA," Yost said. "That's not a good enough excuse right now. The bottom line is, 'Do you win the game?'"
• Royals general manager Dayton Moore said left-hander Jason Vargas had Tommy John surgery last week.
"From the reports that we got, it went well," Moore said.
The Royals do have insurance on Vargas' contract -- it seems likely Vargas would miss all of 2016 because Royals pitchers who have that surgery generally don't get back to the Major Leagues for 14 months.
