This module is used to implement {{Team roster navbox}}, a helper template used to implement the individual team roster navboxes for the Major League Baseball teams.
At present, it parses any list<number> arguments to the template and replaces spaces in each list item with in order to prevent wrapping. It then calls Module:Navbox._navbox() to create the navbox. (Note the preprocessing done by Module::Navbox.navbox() has not been copied to this module and so is skipped.)
