Pederson is out of the lineup for Sunday's game against the Phillies, Alex Weiner of ArizonaSports.com reports.
Pederson is on fire to begin August with four homers and a 1.276 OPS though nine games, but he'll hit the bench Sunday with lefty Cristopher Sanchez pitching for Philadelphia. Randal Grichuk is batting fifth as the designated hitter in the series finale.
