KOFU, Japan (AP) - Champion Hilario Zapata of Panama predicted Sunday he would beat Japanese challenger Shuichi Hozumi in their World Boxing Association flyweight title bout.

''I have had enough training,'' Zapata said of Monday night's fight. ''It's up to Hozumi, but I will certainly win either by a knockout or decision,''

The 27-year-old Panamanian is making his second defense of the WBA 112- pound title. He defeated Mexican Javier Lucas in a unanimous decision at Panama City in January.

The champion has a record of 31 victories and five defeats with 11 knockouts. Hozumi, the WBA's No. 7 flyweight contender, has won 28 bouts, eight by knockouts, and lost three.

The 15-round bout will be held at Nirasaki, 74 miles west of Tokyo.
