ESPN - Francisco to close for Rangers after Guardado traded - MLB

"Frank Francisco does not have a career save and is 0-for-6 in save opportunities this season, but he will be the Texas Rangers closer for the remainder of this season."

Fortunately, the concept of a closer is more or less purely theoretical when it comes to the Rangers. About the only time a save is ever possible is when they are trying to cling to a 13-12 lead.
