Seniesa Estrada inflicted the fastest knock-out in women’s boxing yesterday as she defeated Miranda Adkins in seven seconds.

The contest, hosted by DAZN in California, was crowded by controversy with many claiming it should never have gone ahead.

Heading into the fight Estrada, 28, was 18-0 while Adkins, 42, had five wins under her belt but had fought only local Kansas debutants and started boxing two years ago.

While the WBA sanctioning body, promoters Golden Boy and broadcasters DAZN all hailed the victory as boxing history, many condoned the bout.

Trainer Russ Abner wrote on Instagram: "In my 40+ years in this game, I have seen some terrible s***.

"However, this ranks up there as one of the most sickening, disgusting things I have ever seen.

"Whoever was responsible for sending that poor, helpless woman into the ring should be tried for premeditated assault!

"You should be ashamed of yourselves. May this vision haunt you for the rest of your lives! You are disgusting!

"I am sickened and embarrassed for boxing! Who the f* let this happen!?? F***s all of you!"

ESPN reporter Ben Baby said: “Estrada was 18-0 coming into this. Her opponent, Miranda Adkins, is 42 with a total of five pro fights. The result? A seven-second KO. Scary to think this could have been even worse.”

And boxing writer Kevin Iole wrote: "It was one of the worst things I have ever seen. This woman belonged nowhere near Seniesa Estrada. That was DISGUSTING."

Estrada herself admitted the fight was mismatched in her post-bout interview.

She said: "I give Adkins so much credit because she stood up and took the fight.

"Due to the Covid situation we tried to get current champions, former champions, and Miranda was the only one who stepped in to take the fight.

"I had more experience than her in the professionals and amateurs, so I let my punches go and couldn’t stop.

"I knew the outcome would be a knockout for sure, but didn’t know how long it would take. God bless Adkins and hope she is OK."
