One example of a line illustrating what it describes comes at the beginning of stanza one: “He stands ready for his chance/ His movement is all but still;/ He does not shift or glance…” (Francis). This sets up an immediate contrast between motionless stillness and impending action; while physically standing still, mentally he is prepared for whatever may come next – just like any good pitcher who faces down an incoming batter calmly yet confidently waiting for his turn at bat. Later in this same stanza we find another illustration when the speaker references “the violent force/ Of his right arm uncoiling like some bright snake/ With poised head ready now straight to strike…” (Francis). Here again Francis creates a visual image that aptly portrays how quickly yet coolly a successful pitcher must act in order to take down their opponent; Snake-like agility plus focused determination equals success every time.

Moving into subsequent stanzas we find more examples where Francis uses words as pictures depicting different facets of pitching greatness: In stanza two we see imagery related to sailing ships used when discussing how pitchers must be able “to make swift course corrections…From curve whitecaps risings…” (Francis); here acknowledging both the importance of flexibility as well as precision accuracy when controlling speed – something key when delivering pitches effectively without allowing batters any advantage whatsoever . Similarly, Stanza three illustrates how even those most dedicated will sometimes miss their mark with lines evoking feelings frustration such as “And if his aim misfires/ Then nothing cheers him more than risking” (Francis). Lastly Stanza four provides us with perhaps one most beautiful visual analogies found anywhere in poetry today: “A star might spin his comet’s tail around / By such sharp inward curves….In dreamy spiral circling round…”(Franics) Allowing readers understand precisely why certain players go above beyond mere mortals – because they have something special no one else can ever recreate – something supernatural almost magical which allows them overcome anything thrown way…just like bright shooting star!
