Would you like one word per letter for Acrostic, or a verse for each letter?
When someone makes reference to a familiar story or cultural reference, such as Ulysses and Achilles from Homer's "The Odyssey", it is considered an allusion.
Since I don't know what word is underlined, I will just list everything. 'Marty' is a noun, 'sensed' a verb, 'his' pronoun, 'baseball' noun, 'team' noun, 'was' verb, 'in' preposition, 'trouble' noun.
