Canelo Alvarez
Mexican boxer Canelo Alvarez began boxing when he was just 13-years old, inspired by his older brother Rigoberto, who was a professional boxer as well. He began professionally in 2005 and has fought over 50 fights, losing only once, and can you guess to whom? Floyd Mayweather of course. But despite that, he has had a very successful career so far, earning $44.5 million in just the past year.
