Kailan Hill is having a heck of a year.
The explosive middleweight picked up his third first-round knockout of the year, blasting Andre Walker with a stunning spinning backfist that ended the fight just 11 seconds into their bout at LFA 54 on Friday in Costa Mesa, Calif.
In the clip above, Hill can be seen timing a spinning strike that lands with such impact, it causes Walker to go limp and turn 180 degrees before plummeting to the mat.
Hill added to his 2018 highlight reel that includes a 78-second KO of Alex Thompson and a 91-second KO of Adam Fugitt. He remains undefeated in four pro bouts.
