Moustakas is dealing with a mild hamstring strain, which is keeping him out of Tuesday's lineup, Joel Goldberg of FSKC reports.

EDGE Analysis

Ben Zobrist is starting at third base in Moustakas' place, but manager Ned Yost indicated that Moustakas could play, if need be. With the Royals holding a comfortable cushion in the AL Central, they'll hold him out Tuesday, and he could miss another day or two if discomfort persists.
