Rob Brant delivered by far the biggest win of his young career to date, knocking out Decarlo Perez in highlight reel fashion Friday evening at Casino del Sol in Tucson, Arizona.

The Showtime-televised main event ended with Perez stretched out over the middle rope before collapsing to the canvas courtesy of a right hand at 0:38 of round four. 

Brant enjoyed a quick ring turnaround, having survived a stiff test from Louis Rose in securing a 10-round decision in a bout that also aired on Showtime's ShoBox The New Generation series last October in Phoenix. Perez was regarded as a live underdog heading in, but was unable to keep up with the furious pace set by Brant from the opening bell. 

With each round, it was evident that Brant was reaping the benefits of the work put in with unbeaten rising prospect-turned-contender Errol Spence Jr. The St. Paul, Minn. native even trained out of the Dallas area - Spence's corner of the world - in preparing for his second straight televised appearance. 

Perez - who lives in Atlantic City but trains out of nearby Philadelphia - was not without his share of quality gym work, having put in several rounds with top-rated super welterweight contender Julian Williams. The tough training he's enjoyed in the past has led to his recent career turnaround, but was no help against a rejuvenated Brant, who scored two knockdowns on the night.

After sprinting out to an early lead through two, Brant dialed up the pressure in round three. Perez was left to bear the pain, as a right hand shot put him down for the first knockdown of the night. Things would go from bad to worse, as Brant closed the show early in round four. Another right hand connected upstairs, putting Perez down and out, with the referee stopping the fight without issuing a count. 

Brant improves - in every sense of the word - to 19-0 (11KOs); Perez snaps a four-fight win streak in falling to 15-4-1 (5KOs).

UNDERCARD

Jarrell Miller registered his fifth consecutive knockout, putting away a resilient Donovan Dennis inside of seven rounds. 

The unbeaten heavyweight from Brooklyn twice floored Dennis in the opening round, but was forced to put in work every step of the way beyond that point. Miller came in at a fleshy 274.25 lbs. - a few pounds lighter than his last Showtime-televised outing but still extremely fleshy for his 6'4" frame. It almost didn't matter, as his right hand proved lethal against an opponent not known for taking a decent punch.

Still, a bloodied and fallen Dennis did his best to make a fight out of it. The 28-year old southpaw from Iowa - fighting for the first time since his 2nd place finish in the 2015 ESPN2 Boxcino Heavyweight tournament - rallied back in the very next round, perhaps not making a dent on the scorecards but forcing Miller to work a little bit harder.

Body shots eventually slowed down Miller's attack midway through the fight, though prompting the 27-year old former kickboxer and MMA fighter to return to just letting his hands go. His power punches found their way back to Dennis' chin, landing four clean head shots on his defenseless opponent before the referee finally decided to jump in and end the onslaught late in round seven.

Miller advances to 16-0-1 (14KOs), while the game Dennis suffers his second straight knockout loss in falling to 12-3 (10KOs).

Free-swinging super lightweight prospect Bakhtiyar Eyubov kicked off the 2016 season premier of Showtime's ShoBox: The New Generation with a bang, pummeling Jared Robinson into submission in three rounds.

Eyubov wasted no time in making his presence felt, walking through early power shots from Robinson to floor his foe barely 15 seconds into the contest. Another knockdown came later in the round, with Robinson beating to the count but barely making it to the bell to survive the opening round.

The overmatched boxer from North Carolina was back on the canvas in round two and under siege early in round three before referee Rocky Burke rescued him from absorbing additional punishment.

The offical time was 0:56 of round three.

Eyobuv - a 29-year old prospect from Kazakhstan - improves to 10-0 (10KOs).
