His boxing manager and coach (trainer) was Manny Siaca Sr. that notice Rosario's talent since he was 8 years old. Rosario was inspired by his brother, and had a stellar amateur boxing career.

Papo died unexpectedly, supposedly due to drugs, two years after his brother's move to professional boxing. Rosario persevered, wanting to honor his brother's memory by winning a world championship. He scored big knockout wins over Young Ezzard Charles and Edwin Viruet, the former in 3 rounds on the Holmes-Cooney undercard. He eventually gained a record of 21-0 with 20 knockouts. This led to talks of a title fight against world lightweight champion Alexis Argüello, to be held in Miami, but Argüello abandoned the division to challenge Aaron Pryor.

Thomas made his UFC debut at UFC 32, in a fight against future UFC lightweight & welterweight champion B.J. Penn, where he lost by TKO (Strikes) in Round 1. Thomas returned at UFC 33, defeating Fabiano Iha by unanimous decision.

At UFC 39, Thomas faced Japanese superstar Caol Uno in a rematch. The fight was part of a tournament to determine the new UFC Lightweight Champion. After three rounds, Thomas lost by unanimous decision. His next fight was a split decision victory over future UFC welterweight champion Matt Serra at UFC 41. This fight would prove somewhat controversial, due to one of the judges mistakenly placing the score he assigned to Thomas in the column reserved for Serra^{[citation needed]}. This caused Serra to be declared the winner by decision, but the mistake was discovered and Thomas and his team were notified of the change, giving Thomas the split decision victory. This would be Thomas's last UFC fight for 3 years.
