Pederson went 0-for-2 and stole a base in Saturday's 5-0 loss to San Diego.
Pederson was on the back end of a double steal in the sixth inning but was stranded there. The theft was his career-high seventh. Arizona faces a must-win situation Sunday for a chance at the postseason, and the Padres have left-hander Martin Perez scheduled, which means Pederson is not expected to start.
