Last I saw, the Cleveland Guardians were trying to figure out exactly when to schedule their home opener... which normally would be in progress during the eclipse and Cleveland is almost dead-center on the track of totality. Lots of concerns about (a) whether everybody’s eyes would be protected, and (b) that the dramatically varying light levels would wreak havoc with the batters.
Several minor league teams handled it in 2017. Lots of places near Knoxville TN were giving out or selling eclipse glasses then.
The women’s basketball final is the previous day.
During the partial eclipse, the Sun is as bright as usual. During totality, no glasses are needed at all!
