My Blue Birds are at Wrigley Field today. I learned that the Cubs have a tradition of a guest person leading the crowd in singing “Take Me Out to the Ballgame” in the middle of the 7th inning. Today it was Stephen Colbert! But even without such a big name, I thought that was a really cool and unique feature of Cubs games. (Edit: Cubs also have a song for walk-off wins, which is pretty sweet.)
In Yankee Stadium, they do a roll call in the top of the 1st inning while the Yanks are on the field. The fans cheer each players name 4x, interspersed with clap-clap clap-clap-clap, greeting all 9 players on the field (any maybe the manager too? Did it start this year?). I think it’s brilliant - from business, fan enjoyment, and perhaps even competitive and player enjoyment angles.
Anything else?
