Largest age gaps in title fights where older fighter won

Archie Moore vs Giulio Rinaldi - 19 years.

Moore debuted in the same year when Rinaldi was born. It's unvelievable, especially given that it was a title fight.

Bob Fitzsimmons vs Philadelphia Jack O'Brien - 15 years.

Not as huge gap, but O'Brien was an all-time great LHW in his prime and Fitz dominated him. Truly an all-time great performance.

 

Foreman-Schulz was a 19 year 2 month age gap.
Of course, many people don't think Foreman deserved the decision but officially he won that fight.

 

39 year Daniel Zaragoza beat 26 year Wayne McCullough in a great fight.

37 year old Azumah Nelson beat 28 year Jessie James Lejia.

Not huge age gaps but all the other good ones have taken.

 

Thulani Malinga vs Robin Reid - WBC Super Middle - 16 years

Azumah Nelson vs Gabriel Ruelas - WBC Super Feather - 12 years

Ali vs Spinks - 11 years

Pacquiao vs Thurman - WBA Super Welter - 10 years

Holyfield vs Ruiz - 10 years

 

Had the judges not gifted Foreman earlier, Briggs wouldn't have won the "lineal" title from him despite neither being near the top of the division.

 

Vitali Klitschko had just under 12 years on Charr.
