On April 23, 2014 — Wrigley Field celebrates its 100th birthday with a party that includes birthday cakes, the presence of many former Chicago Cubs greats such as Hall of Famers Ernie Banks, Billy Williams, Fergie Jenkins and Andre Dawson, and everyone dressing up in the style of 1914 when the park was known as “Weeghman Park” and was home to the Chicago Chi-Feds of the long-defunct Federal League. Alumni of the NFL’s Chicago Bears, who played here from 1921 to 1970, also take the field before the game. The Cubs don the uniforms of the Feds, while the visiting Diamondbacks impersonate the Kansas City Packers. The visitors come out on top, 7 – 5, as they score 5 runs against Pedro Strop in the top of the 9th to spoil the party.
