Harvey Cody Jones,,,,,,, 'The Detroit Express' The sparring partner for the young Cassius Clay. Angelo Dundee's 'secret weapon' in preparing Cassius for Sonny Liston, in 1964, and again in 1965. As later, both said that Cody Jones left hook was powerful, maybe not quite as devastating as Liston's, but it was much quicker. The 6' 2" 205 lb. Jones, a powerfully-built left hook bomber from Detroit, should have gone places in the heavyweight division. Unfortunately, developed a 'sparring partner mentallity'. Was 11-3-1 (10 KO's) when he was brought into Miami to help Cassius Clay to prepare for Sonny Liston. Had emerged as a 'Heavyweight to Watch' by Ring Magazine when he held highly regarded #22 ranked heavyweight Jefferson Davis to a 10-Round Draw in December 1963. The slab-muscled Jones sparred with the young Cassius many rounds. The goal, to help Clay avoid the big-swinging left hook, by developing a quick move to his left. On several occasions, Jones landed his vaunted left-hook, dazing the fleet-footed Clay as well as bloodying his nose. He also got a good write-up in Sports Illustrated.
