Jon Heyman of CBSSports.com reports that the Red Sox are "working many angles" and could be seeking an upgrade at shortstop. Mike Aviles and Nick Punto are currently slated to share the shortstop position following the Marco Scutaro trade, but Heyman isn't convinced that the Sox are really prepared to go with that duo. Making a big splash with someone like Hanley Ramirez is unlikely, but it sounds like Boston isn't done tinkering with their infield.
