Guess the champ by weight class & professional career duration

Yes indeed - there was much ballyhoo surrounding Alberto Rossel being the first Peruvian world champion, but many of those reports (even in reputable mainstream publications) failed to qualify that statement with the caveat that he was the first specifically on Team Franks 'n' Beans.

Señorita Malpartida beat him by three years.

 

ROUND 12

• Bantamweight, Featherweight, Super Bantamweight, 16 years, 9 months, 25 days
• Middleweight, 13 years, 8 months, 11 days
• Light welterweight, 14 years, 1 month, 14 days

Hint:

One more for the road...


BONUS FIGHTER/POSSIBLE ADDITIONAL HINT

Spoiler

When this was first drafted weeks ago, I had a fourth name - but was forced to remove them due to recent developments.

• *Lightweight, Light Welterweight, 6 years, 7 months, 5 days

 

He's a stud. And modest:

Before your next hiatus - which, bear in mind I'm only going to be the gamesmaker for a little while longer (the championship rounds, 13-15) until riding off into the sunset myself - do you want to play for the bonus on this one?

And yes, the commonality was that all captured another* world championship (*that wasn't their career first, adding some more specificity onto their unique relationship) in their final ever match.

 

I've got the last few rounds all ready on stand-by.

 

He did last spring, aged 25...but, obviously it didn't stick as he's now scheduled to fight in a week.

The announcement made pretty big waves, guess you maybe took a bit of a break from boxing media circa June?

 

ROUND XIII

• Heavyweight, 24 years, 2 months, 9 days
• Light Heavyweight, 18 years, 6 months, 3 days
• Lightweight, 10 years, 6 months, 8 days

Hint:

Wham, bam, thank you champ.

 

Taking all comers - this is the home stretch, the championship rounds to end the IB era of GTCBWCAPCD. I know @Fogger is recusing himself as he's got several rounds in the bank already but @AntonioMartin1 @Bukkake @Drew101 @Frankus @George Crowcroft @Jel @lone star @Pugguy @Saintpat @thistle @20thCenturyBox @Vic-JofreBRASIL - or any newcomers that want to play - tap in!

 

Super impressive stab for not BoxRecing - you have correctly guessed on Arturo Frias!

As for the hint, not quite that but you are definitely in the right ballpark.
