Brandon Moreno pulled off a stunning upset over No. 9 ranked flyweight contender, Louis Smolka, submitting him with a guillotine choke at 2:24 of the first round.
Moreno opened the fight hot, throwing a kick, and putting Smolka on his back. The 22-year-old son of a pinata maker stayed on top of him, forcing Smolka to fight from his back where he landed a few elbows while holding Moreno in his guard.
Eventually, the Hawaiian rolled out, but it would prove to be the beginning of the end. Smolka went for a single leg takedown, but as he lowered his head, Moreno grabbed him like an attacking cobra, and locking in the deep guillotine choke.
Smolka tried to defend it, but Moreno locked it too tight, and Smolka eventually tapped.
"I feel so happy," said Moreno, a native of Tijuana, Mexico. "I don't believe it. . . What can I say, I am Mexican."
Moreno said via translator that his plan was to be patient, and to avoid getting the infamous Octagon jitters.
"It's magical," Moreno said. "Portland is amazing. Nice people, nice town."
Moreno, who rose to fame on The Ultimate Fighter, was a last-minute replacement for an injured Sergio Pettis.
Moreno moves to 12-3, while Smolka drops to 11-2.
