Raul Rosas Jr. has earned his place in UFC history…

The 17-year-old Mexican mixed martial artist has become the youngest fighter to sign with the UFC.

Rosas signed with UFC Tuesday night, following a unanimous decision win over Mando Gutierrez on Dana White‘s Contender Series.

White, impressed by Rosas’ performance, offered the teen a contract before the end of the show, which he accepted. Rosas is the youngest fighter to compete on the series.

“I’ve never seen anything like it,” White said of Rosas’ age and outing against Gutierrez. “Not only that, the amount of fighters blowing me up saying you’re crazy not to (sign him). … He’s absolutely, positively talented. He’s special, he’s different.”

Rosas, a bantamweight fighter, dominated the 25-year-old Gutierrez for most of the fight with his grappling prowess. He nearly finished Gutierrez in the first round with a rarely used Suloev stretch submission from back control. Gutierrez had moments, taking Rosas down and landing some ground-and-pound. But almost always, Rosas would end up in the better position, using his dexterity, skill and creativity on the ground to scramble his way to the top.

Rosas (6-0) had finished all of his previous opponents before Tuesday night. The Mexican-born fighter, who trains out of Las Vegas, previously fought in the UWC promotion in Tijuana.

Dan Lauzon holds the record as the youngest fighter to compete in the UFC (18 years, 198 days), per ESPN Stats & Information research. As long as Rosas steps into the Octagon within the next 216 days — a likely scenario — he will beat that mark.

And Rosas is already talking about winning championships. The youngest UFC champion was Jon Jones at age 23 in 2011.

“Everybody shouldn’t be surprised,” Rosas said. “I’m the new king in here, so I’m coming for that belt now. … I’m gonna be champion when I’m 20. Respect to everybody, but I’m gonna be champion when I’m 20, or even earlier. Nobody is gonna stop me.”
