MLB and Nike began their City Cinnect series during the 2021 season. 28 of the 30 clubs have received at least one iteration of the jersey between 2021 and 2025, the lone exceptions being the New York Yankees and the Oakland (at the time) Athletics.

The Colorado Rockies unveiled their City Connect uniforms on Saturday, inspired by the colors of Colorado sunsets and sunrises from the plains to the Rocky Mountains. They'll debut the threads on April 18 against the Washington Nationals and wear them on every Friday home game through the remainder of the season.
