Opera at the Ballpark has proven to be a successful mix in the years that San Francisco Opera has been simulcasting a live performance into the baseball stadium… But how about the other way around? What happens when baseball goes to the opera house? The Marx Brothers made Verdi take a left turn into “Take Me Out to the Ballgame” in their movie A Night at the Opera… and American composer (and baseball fan) William Schuman adapted the famous poem “Casey at the Bat” for his opera The Mighty Casey.

There are more details about Saturday’s free (but tickets are required) event at San Francisco Opera’s website. Hoyt and Dianne will be at Oracle Park (and on Diamondvision) hosting the simulcast from War Memorial Opera House to the stadium – which will let fans take to the outfield and seats to watch a performance of Gounod’s Romeo and Juliet.

William Schuman’s The Mighty Casey isn’t the only classical work inspired by baseball – Charles Ives was a fan as well as a player, and wrote a series of improvisations for piano that depicted various scenarios on the baseball diamond.
