Ardmore native Jesse Hernandez defeated Emmanuel Guillen via first round submission at Saturday's King of the Cage: event at WinStar World Casino in Thackerville.
In the heavyweight bout, Hernandez forced Guillen to submit at the 2-minute, 6-second mark with a rear-naked choke. The 25-year-old connected with an overhand left, then shot in for a double-leg takedown.
Guillen was forced to roll over on his stomach, enabling Hernandez to put him in the match-winning submission.
Guillen was in his first professional fight, but was undefeated in 11 amateur bouts entering Saturday. Hernandez improved to 5-0 as a professional.
"I felt really confident," Hernandez said Tuesday. "It was probably my most dominating performance in terms of being well-rounded. My cardio was good, my striking was good, my submissions were good."
Hernandez, ranked 220th in the world in the heavyweight division, considers himself a striker, but said his submission game has been a strength as he's developed.
"When I got into this, the No. 1 thing that I decided to train was submissions, working on my back," he said. "I don't really like going to the ground, but I'm the kind of guy that's not gonna pass up an opportunity when I see it. When I see it, I'm gonna take it."
Hernandez said he is in line for a possible fight in Las Vegas or Oklahoma in January.
"To fight at the next level, I'm going to have to get even better," Hernandez said. "I'm gonna keep working my butt off to make sure those top-level guys don't get a victory off of me."
