After vacating his middleweight crown, Walker fought to a 15-round draw in Brooklyn with Sharkey, who would go on to become world heavyweight champ less than a year later.

10. MAXIE ROSENBLOOM (MAY 8, 1934)
Six months later in Los Angeles, Walker got the better of Rosenbloom via decision in a 10-rounder. Unfortunately for Walker, however, Rosenbloom’s light-heavyweight title was not on the line.
