Hammons Field is officially entering a new chapter as it is renamed Route 66 Stadium through a multi-entity naming rights partnership. The agreement brings together O'Reilly Auto Parts, Missouri State University, Mercy, and the City of Springfield alongside the Springfield Cardinals. The goal of the partnership is to unify branding and investment across the venue while connecting the stadium more directly to the identity of Route 66, which runs through the heart of Springfield’s history.

The rebrand marks a notable shift for a facility that has carried the Hammons Field name since 2004, with signage updates expected in the coming days and a full transition timed around the upcoming homestand schedule. While any name change tied to a long-standing venue naturally brings a range of reactions, the organizations involved have emphasized the collaborative structure of the agreement and its focus on long-term stability and visibility for the ballpark. The result is a new shared identity moving forward under Route 66 Stadium, with baseball continuing at the center of the experience.
