I know it wont win break any records for being short, but Naseem Hamed was gone age 27. That is short!
Leo Randolph's title winning epic against Ricardo Cardona had enough drama to make up for the brevity of his career. David Capo was the first professional to beat Randolph, in what was a huge upset at the time. Capo's final career record was 2W(0 KOs)-19L(2 by KO)-1D, but he was far, far better than that dismal record suggests. His only other win was over Jesus Esparragoza, who was coming off a WBA SB Title eliminator with Carrasquilla, while his draw came against 16(9)-2-0 Albert Colazzo. His career was padded in an obscene way. He went the distance twice with LaPorte, David Kotey, Freddie Roach (in a ten round sizzler on ESPN from the Bradford Hotel in Boston), Julian Solis, and Azumah Nelson in Ghana. He was only stopped in eight by Alberto Mercado, and in seven by Tyrone Downes. Capo was no kind of stiff, and he might have amounted to something considerably more significant with proper management. (If his matches with Randolph and Roach ever find their way to youtube, you'll see what I mean.)
If it's the shortest time holding the little 'n losing it the quickest, I'd have to go with Al Singer, h
This is a new question BUT neither Singer or Turpin is the right answer. Who held a world title the shortest. Lets go by titles that are recognized by BoxRec.
I think this one could be a tie between Waldemar Holberg and Bob Goodwin... who both lost their titles in the ring only 23 days after being crowned world champs.
