Last time a top lb-4-lb fighter got schooled by someone with 11 pro fights.

you aint going to find it this is a 1st, However the last fighter beating an established world champion with that few fights from what I can recall as of now that would be Holyfield over Qawi

 

Rigo is a veteran of over 400 amateur fights and I'm sure he had it rough coming up through the ranks of the Cuban am system. This is certainly a case where his pro record doesn't tell the whole of the story...

 

Last night was the last time this happened.

 

I know Ali didn't get schooled by Spinks, but he did lose while being the reigning champ to a 6-0-1 fighter. Totally different from being schooled as you've asked, but just throwing it out there since you inserted the 11 pro fight part

 

Chan Hee Park vs Miguel Canto

 

Not sure, but Wilfred Benitez beat Antonio Cervantes at 17, closest thing I could come up with.

 

There weren't P4P ratings in the 20's, but Fidel LaBarba fits the bill, winning the World Flyweight Title in his 11th fight at the age of 19, only a year out of high school, over Hall of Famer Frankie Genaro, who was 41-3-3 and had wins over greats like Pancho Villa. You want a tough start to your career? 3 of Fidel's first 5 fights were against Jimmy ****ing McClarnin.

After winning the title, Fidel then gave up the belt after a year to go to Stanford.

Fidel La Barba: An original G.

 

Rigo is way more advandance than those 11 fights.

 

i'm just thinking WTF Rigo would have accomplished if he turned pro in his 20's :yikes

 

To be fair he might not even have been half as good. The Cuban amateur system engrained those fundamentals into him fight after fight. He fought some 20-25 fights a year, and while they were obviously only 3 or 4-rounders, each one mattered, each one was a W or L on his record, and he only lost a small fraction of them.
