Dalton Smith (right) has won all 19 of his professional fights
Britain's Dalton Smith announced himself on the global stage with a coming-of-age stoppage of Subriel Matias to claim the WBC light-welterweight world title in New York.
In a fifth round that lit up Brooklyn's Barclays Center, Smith stood toe-to-toe with the heavy-handed Puerto Rican and dropped him with a looping overhand right.
Matias was left sprawled on the canvas. Although he beat the count, he staggered back to his feet, prompting the referee to wave the fight off.
"Listen, it's the first time in my career I've been the underdog and the first time I've fought a monster," said 28-year-old Smith.
