Former Royals reliever par excellence Dan Quisenberry, whose posthumously-published portfolio of poetry is still available for purchase, starred in this Sports Illustrated commercial back in 1986, at the height of his intimidating career. Quiz was one of the top closers of the 1980s (and perhaps all time) yet did not receive the Hall of Fame love from writers that his contemporaries such as Bruce Sutter or (ugh) Goose Gossage did.
A shame, indeed, but nobody can take away the badassery Quiz displayed in this TV ad. And oh, that moustache!
