Johnson is out of the lineup Wednesday against the Mets, Mark Bowman of MLB.com reports. Johnson will sit in favor of Alberto Callaspo at third base after starting four straight and six of the team's last seven games. The 30-year-old Johnson started just two of the team's first six games. While Johnson appears in line for fairly regular playing time, manager Fredi Gonzalez will continue to employ a soft platoon at the hot corner.
