As an obsessive Sox fan who catches at least 2/3 of the games on TV, I can tell you that Romney was a ubiquitous presence at Fenway while he was governor. The seats are about 20 rows up the from the field, just to the left field side of home plate. From there, Romney was clearly visible (towards the top of the screen) whenever the producers went to the standard shot framing a right-handed batter at the plate.
