why are red sox wearing yellow

The Boston Red Sox are wearing yellow jerseys as part of their City Connect alternate uniforms introduced in 2021. These yellow and blue jerseys are a tribute to the Boston Marathon, held on Patriots' Day weekend, and the colors are inspired by the marathon's official colors. The uniforms feature "BOSTON" in a stencil font across the chest, a "617" area code patch resembling a racing bib, and design elements that honor the spirit of the city and the marathon event. This uniform has become popular due to the team's success while wearing it, with a strong winning record that has led to it being a core part of their uniform rotation. The yellow jerseys symbolize the boldness and culture of Boston and represent a connection between the team, the city, and its iconic marathon.
