The Giants activated Joe Panik on Monday morning, but the All-Star is not in Bruce Bochy's lineup.
Kelby Tomlinson will start at second base for the 13th straight game.
Jackson Williams, who had his contract purchased on Sunday following injuries to Andrew Susac and Hector Sanchez, will catch and bat eighth.
The Giants selected Williams with the 43rd overall pick in 2007, but the 29-year old did not reach the big leagues until making seven appearances for the Rockies last season.
Over 83 games for Double-A Richmond this year, he hit .228 with one home run and 18 RBI.
Buster Posey is playing first base, and Brandon Belt is in left field.
