According to Ken Rosenthal of FOX Sports, the White Sox agreed to a minor league deal with Scott Podsednik.
Podsednik, of course, played for the Sox from 2005 to 2007. They designated him for assignment after '07 and he landed with the Rockies, hitting .253/.322/.333 in 181 plate appearances. The Rox re-signed him in January but released him in April. Rosenthal explains why the Sox brought Pods back:
The move became necessary when center fielder Dewayne Wise left Monday's game with a separated right shoulder. Wise will be placed on the disabled list and is expected to miss six to eight weeks.
