Seven teams started wearing City Connect jerseys during the 2021 MLB season.

• Arizona Diamondbacks, sand-colored with black letters and red numbers, and with "Serpientes" in front as an homage to Arizona's Hispanic community.[2]
• Boston Red Sox, with a yellow base and blue letters as homage to the Boston Marathon, which normally takes place on Patriots' Day.[3]
• Chicago Cubs, dark blue with sky blue accents, with elements inspired by the flag of Chicago. The uniform has "Wrigleyville" on the front, in a lettering style similar to the Wrigley Field marquee.[4]
• Chicago White Sox, in a dark grey shade with white pinstripes and featuring Gothic-styled lettering as homage to the South Side of Chicago.[5]
• Los Angeles Dodgers, with a blue cap, jersey, and pants with “Los Dodgers” written on the cap and jersey. Jersey also includes black on the sleeves as a nod to street art culture in Los Angeles.[6] Cap was revised in 2022, moving the "Los Dodgers" to the side, replacing it with the traditional "LA" logo, and adding black to the brim and button.[7]
• Miami Marlins, with a red base, white pinstripes and white letters with light blue trim as a tribute to the Cuban Sugar Kings.[8]
• San Francisco Giants, with an orange and white design, a silhouette of the Golden Gate Bridge and a unique fog gradient across the front, sleeves and numbering of the jerseys.
