Bridge CS6 Batch Renaming

I take pictures of a swim team and I keyword tag each image with the swimmers name.  I would like to batch rename and save in a new folder the files so they have the original filename and then the keyword name.  I don't see that as an option in the metadata drop down or any of the other drop downs.  Is there a way to do it?  I have exported it and included the metadata information and from my PC I can see it in the lower picture data, but I am sharing with a Mac user and it is easiest if the name of the swimmer is in the filename.  I have over 1100 pictures and renaming them manually would be too time consuming.  Thank you for your input.  MB
