"Raising him right!" an announcer said.
The device was spotted over the left-center stands just as Willson Contreras came to bat.
"C is for Cubbies," yelled the famous Sesame Street Muppet at a Chicago Cubs game.
The actor was accused of staying seated during a military salute at Wrigley Field, but he insists he did rise.
NBC Sports analyst Doug Glanville said he wasn't aware the gesture was made during his live broadcast.
