DETROIT -- First baseman Lucas Duda left the Royals' 6-1 loss to the Tigers on Monday in the seventh inning because of right hamstring tightness.
Royals manager Ned Yost said the tightness likely developed after Duda tried to run out a grounder in the fourth inning.
The Royals described removing Duda from the game as a precautionary move.
Cheslor Cuthbert replaced Duda.
