The Royals trailed 5-1 to the Detroit Tigers on Tuesday night when steady rains forced a delay in their game at Kauffman Stadium.
The Tigers built their lead by scoring single runs in the first and third innings against Kyle Davies before pummeling reliever Joel Peralta for three runs in the fifth.
Davies exited after throwing 96 pitches in four innings.
The Royals scored in the first inning against Tigers veteran Kenny Rogers on an RBI single by Mark Grudzielanek but mustered little else before the rains hit. Mike Aviles extended his hitting streak to 12 games with a double in the first inning.
The rain forced a stoppage of more than 90 minutes, but club officials expected play to resume.
The Tigers pounded their way to a 19-4 victory in Monday’s series opener. The series concludes at 1:10 p.m. Wednesday when Zack Greinke, 7-6, opposes Detroit’s Armando Galarraga, 7-4.
