The Chicago Cubs are shaking up their home jersey options and reintroducing a colorway the team has not worn on the field in nearly 45 years. The Cubs unveiled a new “Blues Alternate” jersey Thursday night featuring baby blue tops that debut April 5 and will be worn for Friday home games this season.

The new uniform will replace the navy “Wrigleyville” City Connect jerseys, which the team is retiring. The Cubs are scheduled to debut the alternate jerseys April 5, when they play the Padres in the first home series of the year. The team will then wear them for Friday home games throughout the summer.

There is a long list of things that the city of Chicago has become known for around the globe. Day games at Wrigley Field certainly make the list, as would the vibrant blues scene and its part in music’s history and evolution.
