De La Rosa felt no ill effects in his left elbow after pitching last Wednesday for Wichita. He gave up four hits and one unearned run with one walk and two strikeouts in two innings.
"Forty-two pitches. There were a lot of foul balls," De La Rosa said.
He expects to make about 75 pitches on Monday night. He's been on the disabled list since Aug. 1, which, if he returns next Saturday, means he will have missed a full month.
The Royals open next weekend's four-game series at Minnesota with a day-night doubleheader on Friday. Gil Meche and Leo Nunez are expected to pitch for the Royals.
No Teahen party: Right fielder Mark Teahen, on the DL with a left elbow injury, now gets daily questions regarding his health, rather than his hitting.
"It's still there," he informed reporters.
"I got a couple rounds of treatment. Then I'll do some throwing. I'll do some running. I'll get a couple more rounds of treatment, and then cheer on the Royals."
Teahen feels more range of motion in the elbow and expects to be ready to play on Sept. 3.
Sweeney rehabs: Mike Sweeney, in his second rehab game for Triple-A Omaha, again was 1-for-3 with a single in the first game of a doubleheader against Round Rock. The Royals won, 5-2.
Moustakas a hit: Mike Moustakas, the Royals' first pick in this year's First Year Player Draft, made his professional debut on Saturday night for Idaho Falls in the Pioneer League.
In his first at-bat, Moustakas doubled in two runs at Ogden.
In Buck's seat: Susan Schuler of Kansas City, Kan., was in the Buck O'Neil Legacy Seat on Saturday night. A volunteer for the American Red Cross, she and her husband have traveled throughout the country helping with disaster relief after tornadoes, floods and hurricanes.
Thomson's tale: Right-hander John Thomson, signed after Scott Elarton went on disabled on June 22, is apparently finished for the season.
"We're not sure if Thomson is going to be able to pitch the rest of the year. He's got something going on in his wrist," Bell said. "He won't be looked at until Monday, so he's been when -- a month and a half? And, at the very best, it'd be the last week of the season or something like that."
Thomson made two starts and went 1-1 with a 3.38 ERA.
