Giants third baseman Casey McGehee (knee) is not in the starting lineup Thursday for the fifth straight game.
McGehee hasn't seen any action since coming out of Saturday's game after just one at-bat due to a strained left knee.
"He came out and he ran. He's not quite ready," Giants manager Bruce Bochy said before Thursday's game, per MLB.com.
Bochy added that head athletic trainer Dave Groeschner estimated that McGehee needs at least one more day of rest. With the third baseman out of the lineup again, Matt Duffy, who has made four straight starts at third base and hit his first home run of the season Wednesday, will start and bat sixth.
The Giants are heavy favorites (-175) against the Diamondbacks Thursday.
