Joey Spencer hopes his first-round demolition of Isiah Seldon on Saturday night is just the start of a busy, productive year.

The 20-year-old junior middleweight prospect wants to fight four times in 2021. The Linden, Michigan, native, who is essentially untested, knows he’ll have to face tougher opposition than Seldon later this year to develop properly.

Spencer still feels he is on track to become a legitimate 154-pound contender by sometime next year.

“I wanna continue to put the world on notice in 2021,” Spencer said during a post-fight press conference after knocking out Seldon. “In 2022, I wanna be in contention at some point in that year. That’s my goal. And in 2021, I’m just gonna keep [putting] opponents away. My management’s gonna line ‘em up and I’m gonna keep on knocking ‘em down, you know, God willing. And then, in 2022, I’m gonna be ready to be in contention for whoever’s got the titles at that time in my weight [class].”

In Seldon, the son of former WBA heavyweight champ Bruce Seldon, Spencer (12-0, 9 KOs) encountered an overmatched opponent who had been knocked out in the first round in two of his previous four fights.

Spencer sent Seldon to the canvas with a right hand just 1:02 into their scheduled eight-round middleweight match at Shrine Auditorium & Expo Hall in Los Angeles. Seldon got up by the time referee Jerry Cantu’s count reached eight and blatantly fouled Spencer soon thereafter.

An emotional Seldon hit Spencer behind his head three times in a row before Cantu could separate them. Cantu deducted two points from Seldon, who went down from another Spencer right hand with 47 seconds remaining in that opening round.

Cantu quickly stopped the bout as soon as Seldon hit the deck a second time. The 32-year-old Seldon (14-4-1, 5 KOs), of Somers Point, New Jersey, protested the stoppage, though he hadn’t done anything to warrant Cantu allowing him to continue.

“I wanted to come out and put on a show,” Spencer said. “I wanted to make a statement. I think I did. And I’m ready to start off a busy 2021.”
