Raul Rosas Jr.

Raul "El Nino Problema" Rosas Jr. is an American professional mixed martial artist competing in the Bantamweight division of the UFC. Born in Clovis, California, Rosas made history as one of the youngest fighters to compete under the UFC banner, signing with the organization as a teenager and quickly demonstrating that his age was no obstacle to competing at the sport's highest level.

A product of Rosas Brothers MMA, Raul grew up immersed in martial arts alongside his brothers, who have been integral to his development as a fighter. The family training environment gave him access to intensive, personalized coaching from an early age, and he progressed through the amateur and regional professional ranks at a pace that stunned observers in the MMA community. His nickname, "El Nino Problema," captures the essence of his fighting persona perfectly: a young man who presents serious problems for every opponent he faces.

Rosas is primarily recognized for his submission grappling, which is technically advanced well beyond his years. He has a natural affinity for the ground game, seeking takedowns and submission openings with creativity and relentlessness. His jiu-jitsu is fluid and adaptive, allowing him to flow between positions and capitalize on opponents' mistakes. However, his game is more complete than simply a submission specialist — he has shown the ability to strike effectively and use his physicality to control pace and position.

The raw excitement of watching a fighter of his background and youth compete at the UFC level has made Rosas one of the division's most talked-about competitors. His trajectory suggests that with continued development and experience, he will be a fixture in bantamweight title conversations for many years to come.
