The RF hole is covered with Goodwin, Hamilton and Engle...Robert and Jimenez fill that outfield need and Hahn survived that loss to this point.
The moves will be in the bullpen and C. My guess it is for guys on the 40 man. Sheets and Vaughn's outfield ability makes a few 40 man outfielders expendable.
The White Sox front office gets input from the team when looking at deadline moves and if they have done so this year I think Leury is the 2B for the duration of the season.
I think they address catcher and relief pitching over the coming days.
