CHICAGO – More will be known about the White Sox’s expanded roster just before Friday’s make-or-break series at Detroit.

The one obvious move will be to activate A.J. Pierzynski from the disabled list where he spent nearly three weeks with a bone compression in his left arm. The White Sox are expected to move forward with three catchers in Pierzynski, Tyler Flowers and Donny Lucy.

The club is also expected to add right-hander Shane Lindsay and infielder Eduardo Escobar from Triple-A Charlotte. Left-hander Hector Santiago is also expected to be called up from Double-A Birmingham.

Triple-A right-hander Addison Reed could also get the call, although his promotion isn’t as certain. Reed is having a standout season, posting a 1.26 ERA with four different White Sox minor-league clubs this season over three separate levels. In 11 outings (21 1/3 innings) at Charlotte, he has a 1.27 ERA with two saves.

Manager Kenny Williams said this week that he is prepared to recall Reed only if the White Sox are in contention. It’s possible that Williams might wait to make a decision on Reed until he knows where the team stands after this weekend’s series against the Tigers.

One move Williams doesn’t seem prepared to make is to call up outfielder Jordan Danks, the brother of pitcher John Danks, who will start in the series opener Friday. Williams believes the White Sox have enough outfield coverage at this time.
