WBC super-welterweight champion Jermell Charlo completely wiped out mandatory challenger Charles Hatley with a punishing shot in the sixth round.
Charlo was in full control for the duration of the bout and put Hatley on the floor initially in the third round.
The 26 year-old dominated further until closing the show in the sixth round with a punishing right hand that knocked Hatley out cold and sent him sprawling through the ropes.
Doctors worked on Hatley for a couple of minutes until he came around before Charlo could fully celebrate an impressive display.
