The greatest feats achieved by "green fighters"

I don't consider guys with extensive amateur careers and and alternate pro bouts (like Loma and Usyk) to be 'green' imo. Same goes for fighters who are highly experienced in other similar combat arts (Thais who make it in boxing are usually (near) ATGs in their own sport). If anything these types of guys should've gone pro sooner.

As for an actual green fighter, I nominate Joichiro Tatsuyoshi. He only had 19 amateur bouts in the space of about 18 months, then won a world title in only his 8th pro outing against the much more experienced and skilled Greg Richardson, about 2 odd years later. Absolutely insane talent imo.

Nearly every other 'green' fighter who'll be mentioned here likely has an extensive high level am career.

 

Spinks v Ali is tough to top

 

Despite losing i love Azumah Nelson's challenge of Sanchez.

 

Rademacher knocked the lineal heavyweight champion down in a pro debut title shot.

 

I'll throw forward Jeff Fenech. Tho he evolved fast in the ams, just like the pro's, he was there for an extremely short amount of time.

Fenech was doing very impressive things in the pro's from extremely early on. He was learning on the job, and he was sure learning fast....especially given his short amateur career.

 

No, Duran and Chang didn't. Chang especially is a good mention. The Thai fighters you mentioned though are extremely seasoned against other seasoned fighters in a full contact striking sport which includes boxing technique, and at least two you mentioned were known for their hand fighting and knockouts in Muay Thai. That's why they adapted to Boxing so well - they'd already been doing it and fighting / training with other guys who also did it. Muangsurin was especially known for his freak punching power - he knocked out over 50 opponents in his 90 odd Thai bouts, which were at the highest level. Nothing green about them at all.

 

Danny Valdez - California featherweight with a record of 14-5 is matched against the #1 contender Ricardo Gonzalez, who sported a record of 94-4-7 with 51 KOs. Valdez upset the applecart on a decision and then had the audacity to stop Gonzalez in the rematch. It was the only stoppage loss on Gonzalez' record at the end of his career after 127 bouts.

Ruben Navarro - with a record of 12-0-1 he is handpicked to take on the jr. lightweight champion of the world Hiroshi Kobayashi, in Japan, no less, in a non-title 10-rounder. Apparently Navarro never received the script as he comes out of the blue to beat the 62 bout veteran world champ.

Pedro Soto - red-hot light heavyweight prospect Soto, with a record of 9-0-1 takes on 52 bout top contender Mike Quarry in New York and loses a tight decision. So tight they rematch 7 months later in Las Vegas where Soto turns the tables on the veteran.

 

Holyfield-Qawi 1

Vargas-Campas

Gomez-Davila

Benitez - Cervantes

 

same goes for Ngannou. I guess he gets a bit of an asterisk for his long combat sport experience, but that was his pro boxing debut. One KD ruled, and another KD that wasn’t recognized but should have counted.

 

Let's get it straight - Ngannou actually beat Fury on that night.

 

I don’t agree with that. Once Fury got into his groove, he cleanly won every round. Ngannou was competitive for a few rounds, knocked Fury down twice, but that was it, the rest was pretty clear in Fury’s favor.

 

If you add the knockdown that you said should have been called, he lost that.
