Citizens Business Bank Arena, Ontario - Olympic silver medal winner, and fast rising heavyweight, Joe Joyce (6-0, 6 KOs) made his United States debut with a fifth round stoppage of Iago Kiladze (26-4, 18 KOs)
Coming in, Kiladze had lost his last two fights by knockout - a sixth round knockout loss to Adam Kownacki in January and then a fifth round KO loss to Michael Hunter in June.
Joyce is now being trained by veteran coach Abel Sanchez and signed a managerial deal with Al Haymon of Premier Boxing Champions.
Joyce was much larger than Kiladze, who had the appearance of a light heavyweight when compared to the much larger Olympian.
Joyce was stalking him down in the first round. Kiladze was moving around the ring and doing his best to stay away from trouble.
In the second, Kiladze was moving away again - but he was decked hard in the first thirty seconds. Kiladze nearly went through the ropes. He got up on unsteady legs and was doing his best to remain on his feet - as Joyce was swinging hard to finish him off. Kiladze barely escaped the round.
During the third, a combination of punches to the head and body sent Kiladze down for a second time. Kildze made it up and starting swinging punches at Joyce to fight his way out of trouble.
Joyce applied a lot of pressure in the fourth, as he was going for the finish, and Kiladze once again was swinging away to fight his way out of trouble.
At the start of the fifth, Kiladze was decked with a big left hand. He got up, but he didn't want any more - as the contest was waved off by the referee.
Also on the card, junior middleweight prospect Joey Spencer (5-0, 5 KOs) demolished Cory Macon (0-3-1) in the first round.
Spencer was unloading with heavy punches from the jump. In the final minute of the first, he put together a series of hard punches that sent Macon down for the full count.
In a fight with plenty of exchanges, bantamweight prospect Jose Balderas (5-0) won a four round unanimous decision over Ivan Martino (3-3, 3 KOs). The scores were 40-36, 39-37, 39-37.
Martino was game and came out pressing Balderas to fight him, and there were moments where the two boxers were going toe to toe in a slugfest.
Balderas had the better boxing skills and sharper shots, but he's not a punhcer and never had Martino in trouble. Martino was able to land some solid punches of his own - which Balderas walked right through.
