Willie Aikens had three hits and drove in two runs, and Kansas City scored four times in the eighth to beat visiting Minnesota.
The Royals had only four regulars in the lineup, with catcher John Wathan, third baseman George Brett and right fielder Jerry Martin out.
Brett will miss at least five games because he has broken a little toe.
Off to his best start in the majors with a .369 average, he banged his left foot on a doorjamb while doing laundry at home before last night's game.
Wathan fouled a pitch off his left ankle Tuesday night, causing a nasty bruise that will sideline him four to five days. Since he and Brett bought Chicago Cubs T-shirts last week, Wathan pointed out, "the Cubs have won seven in a row and George and I are injured." Brett was hurrying to watch a Cubs game on television when he hit his foot on the door.
Amos Otis opened the home eighth with a double and scored on Aikens' single. Pat Sheridan singled pinch runner Joe Simpson to third, and Simpson scored on Greg Pryor's sacrifice fly. Willie Wilson's third hit of the game, a single, sent Sheridan to third, and Onix Concepcion cleared the bases with a triple.
The Royals scored three runs in the fourth in support of Steve Renko (5-4). Dan Quisenberry replaced Renko in the eighth, earning a league-leading 14th save.
