On May 1, 2010, Ramos faced Allen Litzau on the undercard of the Floyd Mayweather vs. Shane Mosley bout at the MGM Grand Las Vegas.

A veteran boxer and sparring partner of Manny Pacquiao, Beltran was Ramo's toughest opponent to date.

[6] In a hard-fought contest, Ramos won by unanimous decision, winning the vacant NABA USA lightweight title.

[7] Ramos was stopped in his last two fights, one against Ricardo Williams Jr. on December 8, 2012, and recently Fidel Maldonado on November 11, 2013, on Fox Sports 1.

Ramos is now in a scary portion of his career where his dream to chase a world championship is starting to drift away following these two fights against inferior opponents.
