Giants catcher Buster Posey and third baseman Casey McGehee are out of the starting lineup Wednesday against the Padres, the team announced.
It will be just Posey's second day off of the season after starting 18 straight games for San Francisco. Andrew Susac will fill in for Posey and bat seventh. McGehee is getting a second consecutive day off to clear his head after scuffling at the plate to start the year. Matt Duffy will get his second straight start.
The Giants are currently the favorites (-138) against San Diego.
