Duckworth has been out since June 14 with a left rib-cage strain, a stretch of 51 Royals games. The oblique injury was a dilly.
"When I was just sneezing, it felt like knives going through me," he said. "It's bad stuff."
Earlier this season, Duckworth pitched in 18 games (two starts) and posted a 2.94 ERA with a 2-3 record and one save. He began the season in the rotation but his emergence as a solid middle reliever was an early factor in the continuing success of the Royals' bullpen.
He'll next pitch for Triple-A Omaha on Wednesday and make perhaps another two or three starts after that, taking him close to the Sept. 1 roster expansion time.
"We're stretching him out. He gives us another option for a starter," manager Buddy Bell said. "As you know, we don't have a lot of options."
In the event of a need in the bullpen, Duckworth could return sooner.
Second at first: Rookie Billy Butler made his second start at first base on Monday night against the Toronto Blue Jays. His other start was on July 18, also with Odalis Perez as the starting pitcher.
What's this? Perez has a personal first baseman?
"I thought I did a pretty good job for him," Butler said, going along with the joke.
Seriously, folks, Bell believes that Butler has worked very hard at first base in pregame drills while filling Mike Sweeney's DH role regularly.
"He has an idea of where he is on the field and his hands work really good," Bell said.
