Major League Baseball and Nike introduced the City Connect series during the 2021 season to shake up uniform design across the sport in the most dramatic fashion since the league introduced the Turn Ahead the Clock alternates in the late 1990s.
Nike has worked with each MLB team to craft a uniform that expresses the personality and communities of the team's home city. Last year saw the launch of seven City Connect uniforms: for the Arizona Diamondbacks, Boston Red Sox, Chicago Cubs, Chicago White Sox, Los Angeles Dodgers, Miami Marlins and San Francisco Giants.
