The Royals will have just concluded a 10-game road trip that ends in Chicago before returning home for a season-ending regular-season six-game homestand starting Sept. 26.
Thursday's postponement could be a break for manager Ned Yost and the Royals' starting pitching situation. Kansas City would have been searching for a starter on Tuesday because right-hander Nate Karns isn't eligible to return from the disabled list until Wednesday.
Rookie right-hander Miguel Almonte was scheduled to make his first Major League start on Thursday, with right-hander Ian Kennedy scheduled for a Friday start. The Royals confirmed they will keep Kennedy on his regular schedule Friday. Almonte could be pushed back to Tuesday, when Kansas City is home against Detroit.
