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 is scheduled to debut the new alternate jerseys on Saturday, April 5, when they play the Padres in the first Wrigley Field series of the year. The team will then sport them at home on Fridays 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.
