7120
For there seemed but little chance of Casey getting to the bat.
7121, prime
But Flynn let drive a single, to the wonderment of all,
[Thanks for the explanations!]
7122
And Blake, the much despisèd, tore the cover off the ball;
[We’ll make you a baseball fan yet. Just remember to cheer for the Toronto Blue Jays.] 
7123 = 17 x 419
And when the dust had lifted, and men saw what had occurred,
[That would be remarcable. But as I am considering giving up football/soccer…]
