Cubs.com blogger Carrie Muskat says that OF Brett Jackson should not be expected to be called up on Tuesday when the roster spots of Reed Johnson, Paul Maholm, and Geovany Soto are filled. Wellington Castillo and Casey Coleman are likely to be called up to replace Maholm and Soto on the active roster.
With Jackson not being called up, the most logical choice would be Dave Sappelt, who is hitting .252 with 4 HR and 35 RBI with the Iowa Cubs this season. He has major league experience with the Reds, and came over in the Sean Marshall trade. He also hits from the right side, which would make him a logical choice to replace Johnson. Sappelt is hitting .318 against left handed pitching in Iowa this season, so he could realistically platoon with David DeJesus as Johnson has been doing since DeJesus moved over to center field.
