Stevenson became the first Team USA male fighter of the 2016 Rio Olympics to conquer a world title.

Stevenson already knows what he wants the next challenge in his career to be.

Mikaela Mayer, the former Olympian and now one of the biggest attractions in women's boxing, defeated Alejandra Zamora by technical knockout in the sixth round to retain her NABF super featherweight title.

Mayer was the aggressor from the opening bell and connected strong blows looking to finish the fight early, but surprisingly Zamora took everything Mayer threw at her. It was not until the end of the fifth round that Zamora's corner did not allow the Argentinian to continue fighting.

Undefeated bantamweight contender Joshua 'Night Night' Greer retained his World Boxing Council (WBC) Continental Americas title and captured the World Boxing Organization (WBO) NABO belt by defeating Antonio Nieves by unanimous decision.

Greer, who improved to 22-1-1, 12 KOs, raised the intensity level from the sixth round on and took control of the fight. Nieves dropped Greer in the final round, but Greer recovered without problems and managed to finish the fight.
