Johnson is not in the lineup Saturday against the Mets, Mark Bowman of MLB.com reports. Manager Fredi Gonzalez will turn to switch-hitter Alberto Callaspo to man third base Saturday, which makes sense given Johnson's 3-for-15 career mark against right-hander Dillon Gee. The third-base situation in Atlanta is being labeled as a "soft platoon," meaning Johnson will start against lefties and some, but not all, right-handers.
