In 2014, the Cubs celebrated the 100th anniversary of Wrigley Field, which opened April 23, 1914. But that was an opening for the Chicago Federal League team, first known as "Chi-Feds," later the Whales.
The Cubs moved into Wrigley Field in 1916 after the Federal Baseball court case dissolved the Federal League and gave Cubs ownership to Charlie Weeghman, who had owned the Whales. The park was first named for Weeghman.
Thursday, the Cubs introduced the logo that will be used throughout the 100th anniversary celebration of the Cubs' first year in the ballpark now known as Wrigley, 1916. You can see it at the top of this post. The Cubs said in a media release:
The logo, which features a version of the team’s 1916 logo in modern colors, will be showcased as a patch on the team’s home uniforms throughout the 2016 season. Fans will be able to purchase officially licensed memorabilia with the logo beginning this offseason. Additional plans to celebrate a Century of the Cubs at Wrigley Field will be released prior to the 2016 season.
The Cubs did play a 100th-anniversary game April 23, 2014, the precise 100th anniversary of the first major-league game played at Clark & Addison. I must confess I'm a bit disappointed that on April 20, 2016, the 100th anniversary of the first Cubs game at what is now Wrigley (that game was April 20, 1916, a 7-6 win over the Reds), the Cubs will be playing the Cardinals in St. Louis.
I'm sure they'll figure out a suitable date to have the 100th-anniversary festivities.
