"This is just to give Este a rest," manager Buddy Bell said. "Este has not been 100 percent. I want to play him tomorrow. I was going to give him a rest one of these two games. Tonight just seems to make more sense."
Cortez, who was recalled from Triple-A Omaha on Tuesday to provide infield help, will play in his second game of the season and 10th of his big-league career. It was the first time he started a game since July 19, 2005, when he played for the Devil Rays. He singled in his first at-bat for his second Major League hit and first since July 17, 2005.
"I am excited and looking forward to the game," he said. "I would like to help the club win a ballgame."
Sanders update: Reggie Sanders, on the disabled list since May 3 with a left hamstring tear, is progressing from his injury, taking batting practice on a daily basis and starting to run more.
"Running is probably the most important thing here," Sanders said. "I have to build my legs back up, too, since it has been so long since I have been out there. So, I am building the legs back up and making sure it is OK, and getting my swing back at the same time."
Bell said Sanders is eight-to-10 days away from returning.
"I am getting better each day," Sanders said. "I would probably be at 80-85 percent right now."
Sanders, who will make the trip on the team's upcoming road trip that starts on Monday in St. Louis, has also provided plenty of veteran leadership to the many young players on the Royals' roster -- young players that have started to turn KC's season around.
"I know the talent that these young guys have and that it would be a matter of time before they would break out," he said.
Gload update: Ross Gload, on the DL since May 14 with a right quadriceps tear, will not return to the team for a few more weeks.
"Reggie is a little further than Ross is," Bell said. "Ross' tear looks like it has scarred up pretty good. We just want to make certain he is completely healthy before he goes back out there."
