Moustakas isn't in the Angels' lineup Saturday against the Diamondbacks, Sarah Valenzuela of the Los Angeles Times reports.
Moustakas is 4-for-17 with a home run and two RBI through five games since joining the Angels, and he'll get a day off Saturday. Hunter Renfroe will make a rare start at first base in Moustakas' absence, allowing Mickey Moniak to start in right field and bat in the leadoff spot.
