Unbeaten At Their Prime Weights

He was beaten by Jorge Ahumada.

 

many would dispute tito undefeated run at 147. floyd was unbeaten at junior lighweight is well. many would argue that he lost his 0 against castillo

 

Here's one for you: Terry Marsh unbeaten at Light Welterweight, 26-0-1.

Retired due to being diagnosed with epilepsy.

The only British World Champion, to this date, that retired has an undefeated world champion.

 

Hearns 154

 

It depends how you interprete Catchweight matches; because someone like Ray Robinson did lose a fight weighing 147 or less....

 

Not on the judges cards tho. This was the fight that made him realise it was time to go however, i believe.

 

Oscar De La Hoya, 22-0(19) at super-featherweight, lightweight and light-welterweight

 

I would say DLH's prime weight was 147 personally, its debatable though, given that he looked very good at the lower weights.

 

manny pacquiao was 11-0-1 (all wins by KO) at 122, his prime weight.

 

Gene Tunney is an interesting discussion here, he lost at LHW, but was undefeated and unified world champion at HW.

 

I believe ROBERTO DURAN went 62 wins from 63 bouts at Lightweight. At that point, after defeating De Jesus, he held both the WBC & WBA Lightweight titles. His single loss at Lightweight being an earlier points loss, also to De Jesus.

Duran vacated the Lightweight titles not long after (in Jan 1979), went up to Welterweight, and soon had his first match-up with Sugar Ray Leonard.

 

So he wasn't unbeaten at his prime weight.

 

Tho "technically" they both came in over 135 so it could be discounted

 

During the first six & a half years of JEFF FENECH's career he racked up 26 wins and a draw including IBF BW, WBC SBW & WBC FW world titles.

Even the draw in the 1st match against Azumah Nelson was an absolute rip-off.

Fenech was fighting in his 4th weight division before he suffered his first loss (in his second match with Nelson)!
