Millerettes Take Opener PERU, ILL. Following an old Minneapolis custom, the Minneap olis Millerettes won their first exhibition game of the season here. They defeated an unofficial Rock- ford nine, 8-1, thus getting a psychological jump for they open the season at Minneapolis against Rock ford's Rockets Saturday afternoon. Neither lineup was official and changes will be made before the All American Girls Ball league opens, but Lorraine Borg proved that she has just about cinched t he catching post for the Minneapolis outfit. She hit well and was skill ful behind the bat.
