TOKYO: “Monster” Naoya Inoue of Japan on Tuesday successfully defended his World Boxing Organization junior bantamweight title, flooring Philippine challenger Warlito Parrenas with a quick knockout. The bout marked a return to the ring for Inoue (9-0, 8 knockouts), who missed most of this year after injuring his right hand in beating Omar Narvaez of Argentina a year ago for the title. The boxing wonderboy released fast and heavy punches, which put 32-year-old Parrenas (24-7-1, 21 knockouts) on the canvas quickly in the second round. Inoue then followed up with killer left-hand blows that had the Philippine fighter on his knees. Inoue grabbed the WBO crown last year, dethroning Narvaez who had defended the belt for 12 years with a second-round knockout.
