Hemi Ahio didn’t have to put in much work to preserve his unblemished record.

The Auckland-based heavyweight extended his current five-fight stoppage streak following his early win over locally-based Christian Ndzie Tsoye. An arm injury forced Tsoye (5-5-2, 4KOs) to quit on his stool prior to the start of the second round of their swing bout Sunday morning (local time) at Marvel Stadium in Melbourne, Australia.

The bout appeared in the background of an ESPN telecast, though with only moments of the fight made available to U.S. viewers. Tsoye appeared to be winded midway through the opening round of a slow-paced bout that never had a chance to pick up steam. The fight ended in an instant, when referee Jeffrey Eddy was alerted of Tsoye’s injury.

Ahio advances to 19-0 (14KOs).

Yoel Angeloni enjoyed a successful pro debut with a win over an unbeaten opponent. The lean Cuban-Italian southpaw from Rome, Italy fended off a determined Ken Aitken to take a four-round, unanimous decision win. Judges Andrew Campbell (39-37), Brett Manton (39-37) and Martin O’Malley (40-36) all scored in favor of Angeloni—just days shy of his 19th birthday—in their welterweight bout.

The high-contact bout saw Angeloni put his height, reach and speed to proper use against Queensland’s Aitken, who was forced to overcome a cut. Angeloni landed the crisper combinations throughout their preliminary bout, though forced to overcome a cut outside his left eye from a clash of heads in the final minute of the fight.

Aitken falls to 3-1 (1KO) with the loss, while Angeloni—who is signed with DiBella Entertainment—improves to 1-0 (0KOs).

Terry Nickolas fought to a six-round majority draw with Mornington, Victoria’s Lachland Higgins. Nickolas (2-1-1) was placed on the show due to his alignment with fellow Australian-Greek and reigning lineal/WBA/IBF/WBO lightweight champion George Kambosos Jr. (20-0, 10KOs) in the main event, but failed to take advantage of the opportunity, as the former amateur standout is off to a disappointing start to his pro career.

Brisbane’s Taylah Robertson (5-1, 1KO) pitched a five-round shutout over previously unbeaten Sarah Higginson (3-1-1, 1KO). Judges Andrew Campbell (50-45), Brett Manton (50-45) and Martin O’Malley (50-45) all scored the bout in favor of Robertson, who dropped down to flyweight after previously campaigning as a bantamweight.

Opening the show, locally based Pom Thanawut Phetkum soundly outpointed Sydney’s Hussein Fayad over four rounds in their junior lightweight contest. All three judges scored the bout 40-36 in favor of Phetkum (1-1, 0KOs), who picks up his first career victory. Fayad comes up well short in his pro debut, falling to 0-1, though already due to return July 2 in Revesby, Australia.

Headlining the show, Sydney-based Kambosos Jr. faces WBC lightweight titlist Devin Haney (27-0, 15KOs) of Las Vegas, for the undisputed championship.
