Demsey McKean made the most of his stateside debut.

The 6’6” southpaw from Ipswich, Australia remained unbeaten following a sixth-round stoppage of journeyman Don Haynesworth. McKean was in control every round before closing the show 0:27 into round six of their heavyweight affair Friday evening at SNHU Arena in Manchester, New Hampshire.

McKean aimed to make a statement in his first career fight out of Australia, though opted to box in the early rounds. The 31-year-old heavyweight worked his jab against an inviting target in Haynesworth (16-8-1, 14KOs), who has now lost five in a row, all since the pandemic.

Sensing the action was going to be one way, McKean (20-0, 13KOs) picked up the pace midway through the scheduled eight-round affair. A flurry of unanswered power punches had Haynesworth out on his feet late in round four, only to be saved by the bell. McKean continued to apply pressure, ending matters as he had Haynesworth cornered and defenseless in prompting referee Kevin Hope to wave off the contest.

Nelson Perez struck first and maintained his lead all the way to the finish line.

The New England-based Boricua scored two early knockdowns en route to a four-round, unanimous decision victory over Raymundo Rios. Judges Dave DeJong, John Madfis and Eddie Scuncio all scored the contest 40-34 in favor of Perez in an entertaining but one-sided junior welterweight affair.

Rios (3-8-2) came out purposeful, having his moments early and a split second away from producing a very different fight. Both fighters exchanged left hooks, with Perez just a hair quicker in depositing Rios onto the canvas. It changed the tempo of the bout, with Perez (5-0, 2KOs) sending Rios to the canvas in round two—once again courtesy of a left hook—but unable to put away the 33-year-old Mexican in having to settle for a points victory.

Khalil Coe was forced to wait more than a month for his second pro fight.

The only success he found was making weight this time around, having to settle for a four-round majority decision draw with Aaron Casper (6-4-2, 4KOs). Coe won 39-37 on one card, overruled by matching scores of 38-38 to produce the draw verdict in the opening bout of the evening.

Coe (1-0-1, 1KO) boxed well early, though quickly found himself at a power disadvantage. Casper looked to assert himself, closing the fight strong in throwing substantive combinations while Coe employed lateral movement in largely playing defense down the stretch. It ultimately cost him a win, though the tactic seemingly necessarily to combat fatigue.

The bout was originally due to take place October 16 in Fresno. Coe ruined plans after missing weight by seven pounds as he was removed from the show. The rescheduled affair comes six months after his pro debut this past May 29 on the undercard of Devin Haney’s 12-round win over Jorge Linares at Michelob ULTRA Arena in Las Vegas.

Thomas O’Toole skipped out on his college graduation to move forward with his second pro win.

The Irish southpaw fought as if the ceremony was immediately to follow, needing just 91 seconds to knock out Mark Malone (1-1, 0KOs). An overhand left was enough to flatten Texas’ Malone, with the fight ending on the spot at 1:31 of round one in their cruiserweight bout. O’Toole scored a first-round knockout in his pro debut two months ago in Dedham, Massachusetts.

A four-fight preliminary undercard precedes four title fights which air live on DAZN beginning at 8:00 pm ET.  Headlining the show, Providence’s Demetrius Andrade (30-0, 18KOs) attempts the fifth defense of his WBO middleweight title versus Ireland’s Jason Quigley (19-1, 14KOs).
