It had been only twenty-four hours since Mighty Casey struck out, plunging fans of the Mudville team into gloom and despair. But a new game day dawned, and Casey once again proved his might with a homer in the eighth. The Mudville nine took a one-run lead, but in the bottom of the ninth, their hurler walked three straight.
