why do red sox wear yellow

The Boston Red Sox wear yellow jerseys as part of their "City Connect" alternate uniforms introduced in 2021. These bright yellow and blue jerseys pay tribute to the Boston Marathon and the spirit of Patriots' Day weekend, reflecting the main colors of the marathon. The design includes "Boston" stenciled across the chest and a "617" patch on the sleeve representing Boston's area code, styled like a marathon bib. The colors symbolize the boldness and culture of Boston as well as the resilience shown after the 2013 Boston Marathon bombing. These uniforms have become popular and are now a regular part of their uniform rotation for home Saturday games and other select occasions due to their connection to the city and the team's successful record when wearing them.
