Over the years, we have seen professional teams honour the other teams they share the city with by dedicating an entire theme night to the other team.
The San Jose Sharks hosted a Golden State Warriors Night earlier this year, the Los Angeles Kings and Los Angeles Dodgers host special nights for each other every year, and the Anaheim Ducks and Los Angeles Angels of Anaheim show each other some love every year as well.
Not many teams have the same colour schemes as the Arizona-based teams, but they manage to make it work.
Some of the members of the Diamondbacks are taking in the game as well.
We're big fans of when teams show love for the other teams in the city like this, especially when custom jerseys are involved.
