One example from Casey at the bat was "one scornful look from Casey and the audience awed." They treated Casey and the like he was a god or something. He used irony to make the point of how they looked up to him which was humorous. Another example is "there is no joy in Mudville - mighty Casey has struck out." Its saying how they believed in him to win the game. It is ironic because he was such a show off that it rendered the game. Finally my last example is when Casey
says "say that aint my style." That is ironic because maybe if he hit at the ball, he maybe wouldn't of lost the game for his team and fans due to him being cocky.
In conclusion, this is what I gathered from the story. There is probably more but these were the three i found. That is all I got left to say the end.
