Beach Convention Center on 17th Street in South Beach. Diehl knocked
out Deboe Bickering in one round.
Probably most familiar to TV audiences as Det. Larry Zito on the smash
hit 1980s cop series Miami Vice (1984) and most recently as the spirit of
pioneering GM auto designer Harley Earl in a series of commercials for
Buick.
Took his undefeated boxing record of 3-0 to the Sports Arena in Los
Angeles to fight winless Gene Holly 0-6-0. Diehl lost the four-round
decision on April 11, 1986, and retired from boxing after the
fight.
