Arizona - The storm came in a hurry, as Isaac "Royal Storm" Dogboe blasted out Hidenori Otake via TKO at 2:18 of the opening round to retain his WBO super bantamweight world title.
Dogboe (20-0, 14 KOs) knocked down Otake (31-3-3, 14 KOs) down twice in the round, and a follow-up flurry forced referee Chris Flores to call a halt to the bout.
Dogboe won the title with a thrilling 11th-round TKO against Jessie Magdaleno in April. This time, he had a shorter night at the office.
"This was a great performance. I'm glad I got to showcase my skills on ESPN," Dogboe said.
I'm very thankful for the opportunity. I have a lot of respect for Otake for standing up after getting dropped. When I hit him with that powerful hook and dropped him the first time I felt the holy spirit.
"Now, I want to face all the champs. Lets do this. I'm ready to unify all the titles."
In the ESPN-televised six-round special attraction, Mikaela Mayer (7-0, 4 KOs) knocked down Edina Kiss in the first round en route to a third-round TKO after Kiss did not come out for the fourth round. Mayer, a 2016 U.S. Olympian, is 4-0 in 2017.
"I'm happy with my performance. I was technically sound," Mayer said. "I thought I had it in the bag. I wanted to stop her. If I had one more two more rounds, I would've finished it."
In other action - Super Featherweights: Robson Conceicao (9-0, 5 KOs), unanimous decision, 8 rounds, Edgar Cantu (7-5-2, 1 KO). Scores: 80-71, 80-71, 80-71.
Conceicao said: "It was a very good fight. I trained very hard, and little by little, I'm showing what I'm capable of doing inside the ring. I wanted to go the full eight rounds. This was my first time fighting to eight rounds, and I wanted to test myself. I felt great. I'm ready to fight more rounds in my next fight."
