Austin Trout's body blows made the difference against Joey Hernandez on Tuesday night in the Premier Boxing Champions event at the Hollywood Palladium.
Trout knocked out Hernandez at the end of the sixth round in the super-welterweight bout.
Trout, a former world champion at 154 pounds, finished off the flashier Hernandez with three consecutive body shots — a right and two lefts that made Hernandez crumple to the mat on his knees.
He was unable to get up, getting counted out by referee Jack Reiss.
"If you looked at his body language, it looked like he was ready to be done," said Trout, who improved to 30-2 with 17 knockouts.
