Salvador Sanchez (1958–1982) was the WBC featherweight champion and widely considered one of the greatest fighters in history, having never lost a professional fight before his tragic death in a car accident at age 23.
Sanchez was technically brilliant, mentally tough, and physically gifted. Boxing historians consistently rank him among the all-time greats despite his brief career.
