Question

Why does it say Eamus Catuli in right field at Wrigley field. Also what does it mean?

Answer 1

"Eamus Catuli!" (roughly Latin for "Let's Go Cubs!"—catuli translating to "whelps", the nearest Latin equivalent), flanked by a counter demonstrating the Cubs' long legacy of futility. The counter is labeled "AC," for "Anno Catuli," or "In the Year of the Cubs." The first two digits indicate the number of years since the Cubs' last division championship as of the end of the previous season (2007), the next two digits indicate the number of years since the Cubs' last trip to the World Series (1945), and the last two digits indicate the number of years since their last World Series win (1908). It is not currently known what the LBC will do if the Cubs reach 100 years without a World Series title.

Answer 2

It means Go Cubs in Latin.
