International Boxing Federation minimumweight champion Ginjiro Shigeoka of Watanabe Boxing Gym successfully defended his title for the second time as he knocked out sixth-ranked challenger Jake Amparo of the Philippines in the second round on March 31 in Nagoya.

  The knockout of the scheduled 12-rounder at Nagoya Congress Center came 1 minute and 15 seconds into the round when the left-handed Shigeoka landed hard left to the body, sending his taller opponent down for the count.

  Amparo’s damage was such he remained on the canvas when the referee’s count tolled 10.

  Amparo replaced ninth-ranked contender ArAr Andales, also of the Philippines, at the last minute as Andales cancelled his challenge to Shigeoka earlier this week due to his poor health condition.

  After the fight, Shigeoka, 24, said, ‘’While there were lots of things before the fight (the sudden change of his challenger), I did not think I was able to knock him out with that kind of body shot.’’   With the victory, the undefeated Shigeoka improved his record to 11 wins, nine by KOs, with one no contest. For his part, the 26-year-old Amparo sagged to a 14-6-1 win-loss-draw tally with three KOs. The fight was held as part of ‘’3150FIGHT vol.8’.’
