Jezreel Corrales pulled a major upset on Wednesday, knocking out long-reigning junior lightweight world titleholder Takashi Uchiyama in the second round at the Ota-City General Gymnasium in Tokyo.
Corrales, a 24-year-old southpaw from Panama, entered the bout as the interim titleholder and mandatory challenger for Uchiyama, 36, of Japan, who was undefeated and making the 12th defense of his 130-pound world title, which he had had held since 2010.
But Corrales (20-1, 8 KOs) defeated Uchiyama (24-1-1, 20 KOs) in stunningly easy fashion. He nailed him with an assortment of fast combinations and knocked him down three times in the second round.
Midway through the round, Corrales connected with a clean left hand to the chin that Uchiyama did not see coming. Uchiyama went down hard, and although he beat the count he appeared shaky, and it appeared to be only a matter of time until Corrales finished him.
Moments later, Corrales fired another combination, and Uchiyama went down again.
Uchiyama survived the next minute, but got tagged again by another left hand and went down to his backside, prompting referee Robert Hoyle to wave off the fight at 2 minutes, 59 seconds, sending Corrales and his corner into a wild celebration.
There were two other world title bouts on the card:
• Junior bantamweight titlist Kohei Kono (32-8-1, 13 KOs), 35, of Japan, retained his belt for the third time, easily outpointing southpaw Inthanon Sithchamuang (28-8-1, 17 KOs), 29, of Thailand.
All three judges scored the fight 119-106 in favor of Kono, who scored knockdowns in the fourth, fifth and seventh rounds.
• Junior flyweight titlist Ryoichi Taguchi (24-2-1, 11 KOs), 29, of Japan, retained his belt for the third time in an 11th-round knockout of Juan Landaeta (27-9-1, 21 KOs), 37, of Venezuela.
Taguchi dropped his southpaw rival five times. He scored two knockdowns in the ninth round, one in the 10th round and two more in the 11th round, after which Landaeta's corner threw in the towel to save him from taking more punishment.
Taguchi, who has won all three of his title defenses by knockout, dominated the fight and was ahead 108-96 on all three scorecards at the time of the stoppage.
