Pernell Whitaker (1964–2019) was considered one of the greatest defensive boxers in history, winning world titles in four weight classes while making opponents look hopelessly outclassed.

Career Highlights

• Professional record: 40 wins, 17 by KO, 4 losses, 1 draw
• World champion at lightweight, junior welterweight, welterweight, and junior middleweight
• Olympic gold medalist, 1984 Los Angeles Games

Style

Whitaker's elusive movement, shoulder rolls, and instinctive reflexes made him nearly impossible to hit cleanly. He was widely believed to have outboxed Julio Cesar Chavez and Oscar De La Hoya in controversial draws and decisions.
