From the book Baseball Haiku

game over
all the empty seats
turn blue

— Alan Pizzarelli (b. 1950)
Originally self-published in 1988 as a folded broadside. Reprinted in Baseball Haiku: American and Japanese Haiku & Senryu on Baseball Edited with Translations by Cor van den Heuval & Nanae Tamura (W.W. Norton, 2007)

This is reprinted as a review of the book, which does not need any further review than an example of the one of the book's many poems.
