MANCHESTER, N.H. (AP) — Demetrius Andrade stopped Jason Quigley of Ireland in the second round Friday night to retain his World Boxing Organization middleweight title at Southern New Hampshire University Arena.

The 33-year-old Andrade, from Providence, Rhode Island, improved to 31-0 with his 15th knockout, dropping Quigley (19-2, 14 knockouts) three times.

In the second round, Andrade sent Quigley to the canvas with a left to the temple. After Quigley got up Andrade swarmed over him and dropped him in a corner with a right hand to the top of the head. Referee Arthur Mercante, Jr. stepped in and stopped the fight at 2:24 of the second round.

In the final minute of the first round, Andrade floored Quigley with a left hand to the body and a right to the top of the head.

Andrade successfully defended the WBO middleweight title he won in October of 2018 for the fifth time. In his last defense, he won a unanimous decision against Liam Williams on April 17. All five defenses were against European fighters.

The co-main event between World Boxing Council flyweight champion Julio Cesar Martinez of Mexico and McWilliams Arroyo was a no-decision after two rounds due to a cut along Arroyo’s left eye that he sustained due to an accidental head butt.

Martinez (16-1, 1 no contest 14 knockouts) retained his title. Both fighters knocked each other down in the first round. In the second, after the cut opened, Martinez dropped Arroyo (21-4, 1 no contest, 14 knockouts) in the second.

World Boxing Association and International Boxing Federation super bantamweight champion Murodjon Akhmadaliev of Uzbekistan retained his titles with a 12-round unanimous decision over Jose Velasquez of Chile. All three judges scored it 119-109. Akhmadaliev improved to 10-0, and Velasquez dropped to 29-7-2.
