Indications are the Cubs will step up their efforts to make another trade of a position player before Monday, when they plan to add a 12th pitcher to the staff. That likely would mean moving Jacque Jones, who has gone from the Cubs' Opening Day starter in right field to essentially the Cubs' fifth outfielder. According to baseball sources, the Padres, Rangers and even the White Sox have shown recent interest in Jones, who has been shopped again by the Cubs in recent weeks. Cubs GM Jim Hendry didn't rule out a trade as a way of making room for the imminent addition of a pitcher when the Cubs return to National League play Monday at home against Colorado.
