After nearly 15 years of the stadium not having a corporate sponsor, the Crew announced naming rights were sold to Madrid-based Mapfre Insurance on March 3, 2015. The team had been searching to sell stadium naming rights since it opened in 1999, but had been unable to come to an agreement. Mapfre maintains an office in Columbus and has its U.S. base in Boston. They were almost relocated but saved by an organization called "Save The Crew" which prevented the relocation.
