The 22-year-old Castro, who won some of the world’s most prestigious amateur titles before turning pro, has stopped all of his pro opponents.

Referee Jack Reiss ended Saturday’s super-featherweight bout with 19 seconds left in the first round.

Mikey Garcia Suffers Upset Loss

In the main event of a card promoted by Eddie Hearn, former world champion Mikey Garcia (40-2) of Oxnard lost by majority decision to Spain’s Sandor Martin.

Sandor received the edge in scoring on two cards (both 97-93) while the third judge called the welterweight bout a draw.

The result was a massive upset in that until Saturday, Martin hadn’t beaten a notable opponent while compiling a 38-2 record.

“It’s the biggest moment of my career,” said Martin. I always said I was going to do it and I’ve done it.”

Said Hearn: “Sandor Martin just got more and more confident as the night went on. It was a massive win. A huge win for Spanish boxing. That’s probably the biggest win in the history of Spanish boxing.”
