Teachers have several different ways of looking at the concept of “theme.” Sometimes we ask students to state a theme as a “statement about human life or human nature,” rather than as just a single word or idea.
If we look at theme this way for “Casey at the Bat,” we have to consider what the crowd at the baseball game expects from Casey and what actually ends up happening. It is obvious from the poem’s description of Casey that he is considered to be a great hitter:
“If only Casey could but get a whack at that—
We’d put up even money now, with Casey at the bat.”
The fans at the game who haven’t left yet are watching, hoping that Casey will get a chance to hit. They clearly believe that he has a good chance to win the game for the home team. Keep in mind that in baseball, hitters fail more often than they succeed, even the great ones. So to be willing to put up “even money” on a hitters’ chances is to express great confidence in that hitter.
However, as is often the case in baseball, the best are likely to fail, and the poem ends this way:
But there is no joy in Mudville—Mighty Casey has struck out.
Themes should be universally true, so we cannot confine our theme to just baseball—we need to make it a little more general. A statement that encompasses the ideas presented in the poem in a universal way could be:
Even the best, despite the expectations of others, are liable to fail sometimes.
This is a viable theme (although not the only possible theme) because it makes a statement about human life that is universally true—it applies to all people, everywhere, all the time.
Baseball is the main theme, of course, in Ernest Lawrence Thayer's (1863-1940) famed poem written in 1887. It tells the story of the legendary Mudville hitter, Casey, and his chance to further extend his popularity and myth when he comes to bat with the bases loaded, two out, and the game on the line. There is a wonderfully unexpected though sad ending to the poem, and this is one of the aspects which has made it so popular for more than a century. It is full of 19th century baseball phraseology, and Thayer builds the tension by creating hope for the fans (and reader) in what begins as a lost cause. Before the final surprise ending, nothing but the greatest expectations appear to be headed Casey's way.
The theme of "Casey at the Bat" is baseball and its emotion. We all have team heros that are larger than life. When these great ones step up to the plate, we expect more of them than others. When they show their human side, we are stung. It is a picture of real life. We have heros and villans and high hopes and cruched dreams. But tomorrow is another game.
