Johan Perez continued to rebound from his first career loss by scoring a 10-round unanimous-decision victory over Yoshihiro Kamegai in the featured bout of ShoExtreme, part of the televised undercard to Saturday’s main event between Josesito Lopez and Marcos Maidana on Showtime.

Perez of Caracas, Venezuela won by scores of 100-90, 97-93 and 98-92.

Perez (17-1-1, 12 knockouts) picked up a welterweight trinket with the win and keeps himself on the brink of contention in the 147-pound division. He lost his “O” last year to Pablo Cesar Cano via seventh-round technical decision. He rebounded with a majority decision victory over Steve Forbes in January 2013.

Kamegai (22-1-1, 19 KOs) of Sapporo, Japan, suffered the first defeat of his professional career.
