A straight right hand was enough to end the fight, as Verdejo put Zavala down and out with the first clean punch he was able to land.
"I want to give the glory to God for allowing me to enjoy me this opportunity of please the fans here in Orlando. I am very pleased (with my performance)," said Verdejo, now 12-0 (9KO). "I boxed as my corner instructed me to, and the knockout just came."
Verdejo has scored knockouts in all three ring appearances in 2014. The rising lightweight prospect - who turns 21 in May - returns to the ring on June 7 in New York City, fighting on the undercard of Boricua superstar Miguel Cotto in his title challenge of middleweight king Sergio Martinez.
The bout will mark Verdejo's fourth trip to New York, and his second appearance on a Cotto undercard. His previous assignment in supporting capacity to his fellow islander came last October, when both fought in Orlando for the first time in their respective careers.
