The Boston Red Sox are wearing yellow jerseys as part of their City Connect uniforms designed by Nike. These special alternate jerseys feature a yellow and blue color scheme inspired by the Boston Marathon's branding. They are meant to honor the Boston Marathon and symbolize Boston's resilience and unity following the 2013 bombing. The yellow jerseys have become a core part of the team's uniforms since their debut in 2021 and are typically worn during specific games, such as Saturdays at home and during events around the Marathon weekend. The yellow uniforms have been popular with players and fans and remain in the team's rotation alongside their traditional reds, whites, and newly introduced green City Connect jerseys for 2025, which honor Fenway Park.
