Mike Tyson vs Don Halpin

'Iron Mike' was scheduled to face Halpin - a more experienced journeyman who held a record of ten wins, 18 losses at the time.
Halpin used this experience to survive early on, though Tyson admittedly appeared to start far slower than he had in his first two wins.
The fight commentator noted, "It's almost as if his corner have said to him, 'Listen, you don't have to win every fight inside one round.'"
In the fourth of this scheduled six-rounder, Tyson decided to dramatically increase the tempo.
