Rizzo is not in the lineup for Saturday's game against the Giants, according to Bruce Miles of the Daily Herald.
Rizzo will get a day off with the Cubs using a lineup full of right-handed hitters against Giants starter Madison Bumgarner. Rizzo tallied two hits Friday, but a day off Saturday may not be the worst thing, given that he is 3-for-16 (.188) with seven strikeouts lifetime against Bumgarner. Kris Bryant will fill in at first base in Rizzo's place.
