Manager Tony La Russa said he would give his starters more rest in the second half to stay fresh at the end of the season, which obviously means late October is on his mind.
Lambert, 3-2 with a 4.89 ERA at Charlotte, made two appearances for the Sox earlier this season, including one spot start. With Lambert on the mound for the series finale, the Sox are able to move Dylan Cease back to Tuesday to get an extra day of rest.
In another move, the Sox placed outfielder Billy Hamilton on the 10-day injured list with a right oblique strain, an injury that sidelined him earlier this season.
