Redman threw two innings, allowing one run and one hit, on Thursday against the Rangers.
"It showed up the next day," Swartz said.
Redman, a 32-year-old left-hander, was acquired in a December trade with the Pirates for
Minor Leaguers Jonah Bayliss and Chad Blackwell. Redman was 5-15 with a 4.90 ERA in 30 starts last season and has a 53-66 career record with a 4.47 ERA.
Manager Buddy Bell had said Redman and Scott Elarton, who signed as a free agent
with the Royals, were the leading candidates to be the Opening Day starter entering
In Redman's absence, left-hander Jeremy Affeldt will start on Monday.
Catcher John Buck said on Sunday that he had the Royals renew his contract, instead of signing.
Buck, who does not have enough service time to be arbitration eligible, was renewed for $349,000.
"Some of the things there was a difference of opinion," Buck said. "The money I'm not that concerned about. In this game, it is not that big of a difference. There were things I did not agree with and they know about it."
Buck, who is scheduled to start, hit .242 with 12 home runs and 47 RBIs in 118 games last season. His 117 games catching were the most for the Royals since Bob Boone caught 129 in 1989.
Brown's aching back:
Emil Brown is out with stiffness in his lower back and is not scheduled to play on Monday.
Brown was scratched from the lineup Saturday, replaced in left field by Shane Costa after his back stiffened while taking ground balls in drills.

"I wouldn't call it spasms, just a little stiffness in there," Brown said on Sunday. "I'm not locking up or anything like that. I've been working so hard it kind of caught up with me. It is nothing serious. It is so much better than it was yesterday."
Brown, who is being treated with heat and ice, did take ground balls and fly balls on Sunday. He said he hopes to be able to play by Tuesday.
Brown said because of the increased ball activities in Spring Training that he would decrease his time in the weight room.
If the back stiffness had to happen, Brown said the timing was right -- early in
Spring Training -- "instead of like a month or two months from now or try to play through it and then miss two weeks instead of three days. That is a good thing."
Right-hander Zack Greinke left camp eight days ago to return to his Orlando, Fla., home for undisclosed personal reasons with the club's permission.
"It is all quiet there," general manager Allard Baird said on Sunday. "There's nothing new, right now."
Normally veterans do not make long trips early in Spring
Training, but first baseman Doug Mientkiewicz was on the bus Sunday for the Tucson trip to play the Rockies.
"I understand the World Baseball Classic is killing me," he said.
He pointed to the locker of Justin Huber and said that this should be his trip. Huber, a rookie first baseman, however, is playing for Australia in the World Baseball Classic.
Korea is coming:
The Royals will host Korea for an exhibition game at 8 p.m. (CT)
on Wednesday at Surprise Stadium. The Koreans upset Japan, 3-2, on Sunday to go 3-0 in Asian qualifying in the World Baseball Classic.
The Royals will play the Rangers on Monday in the first of three
"B" games between the two clubs. Right-hander Steve Stemle is scheduled to start for the Royals. Chad Allen, who has been out with a bruised foot, is slated to
serve as the designated hitter for his first game activity. The Royals are also throwing top pitching prospect Luis Cota.
Affeldt will make his second spring appearance, starting against the Padres. The Royals will also throw Kyle Snyder and Jimmy Gobble. Left-hander Shawn Estes will start for the Padres.
