Fighters who lost to an opponent in the amateurs but got their revenge against them in the pros?

If you consider it a robbery, Oscar did beat Shane in their second pro match after being beaten twice during his amateur career by him.

 

Wasn't the storyline behind Derrik Holmes getting a shot against Wilfredo Gomez that he beat him in the amateurs?

 

I’m pretty sure it was mentioned in the build up that Jermaine Taylor had beaten Kelly Pavlik

I mean, that makes a lot of sense considering how good Taylor can look for a short amount of time and how Pavlik is the type of fighter to build up overtime and wear a guy down
