But Flynn preceded Casey, as did also Jimmy Blake, And the former was a lulu and the latter was a cake; So upon that stricken multitude grim melancholy sat, For there seemed but little chance of Casey's getting to the bat.
The fans feel that Casey is their only hope. One small problem: there are two players that have to bat before Casey can get his turn to hit, and those players are… well, not good. Ever been picked last for a team in PE? Then you know how these guys feel.
Flynn is a "lulu," and Blake is a "cake." As you probably guessed, these terms are meant to disparage these guys—think the opposite of superstar. You never hear someone say, "Yeah, Bob is the best player on our team. He's a real lulu."
The knowledge that these two weak links stand in the way of Casey getting his turn at bat is really bringing the crowd down (remember: one more and the game is over). A sense of "grim melancholy" fills the spectators. No one is doing the wave; no big foam fingers are flying.
The chance of these two guys getting on base to bring Casey to the plate seems slim to zip.
