SAN JUAN, Puerto Rico -- Veteran fighter Giovani Segura confirmed Saturday night what he had been saying all along: his experience would be enough to beat a courageous, yet inexperienced Jonathan Gonzalez.
Segura, of Mexico, a former two-time titlist, used a powerful right hand to disarm the finesse of Gonzalez and knock him out at 2:25 of the fourth round at the San Juan Resort and Casino.
The victory sends Segura, 31, to a possible title shot against flyweight champion, and countryman, Juan Francisco Estrada.
Segura (30-3-1, 16 KOs), fresh off a May loss to Edgar Sosa, sent Gonzalez (13-1, 11 KOs) to the canvas once in Round 2 and twice more in Round 4 -- all on straight right hands -- to finish off the previously unbeaten 22-year-old from Puerto Rico.
"This fight is dedicated to the memory of my manager Arturo Mota," said an emotional Segura. "I want now a fight with Estrada. Simply give me that chance or a rematch against Edgar Sosa or Brian Viloria. I felt strong and better than ever."
The victory was Segura's third consecutive when facing a Puerto Rican opponent. He scored the two biggest victories of his career over former junior flyweight kingpin Ivan Calderon.
"The only thing I have to say is that he is a great world champion," said Gonzalez. "Even though I spoke too much, well this is part of boxing spectacle. But congratulations to Segura, he is a great champion and will be again."
On the undercard, Jonathan Oquendo scored a fourth-round TKO over Miguel Tamayo. Oquendo (22-3, 15 KOs), making his first appearance since a 2012 loss to Wilfredo Vazquez Jr., could become an option to face Ukranian Vassyl Lomachenko in his much-anticipated pro debut on the Oct. 12 Timothy Bradley-Juan Manuel Marquez undercard in Las Vegas.
Former 2008 Olympic gold medalist Felix Diaz, of the Dominican Republic, defeated Mexico's Edgar Llanes by first-round knockout.
