In the televised co-feature of “PBC on ESPN,” junior middleweight prospect Patryk Szymanski remained undefeated with a unanimous decision over Wilky Campfort.

Szymanski looked to have it easy in the opening rounds, boxing well while Campfort had trouble closing the distance on his taller opponent. But Campfort continued to come forward and began to land a little better.

That aggression kept Campfort in range, and Szymanski capitalized by hurting him 45 seconds into the fourth round, then following up with more shots upstairs. Campfort weathered it, stabilized and was able to land a right hand of his own as the round came to a close.

Campfort had his best round in the fifth, landing shots that had Szymanski in retreat for a bit. Szymanski went to his corner with a cut over his left eye, a wound that came from a clash of heads. Szymanski was often staying in range now, and Campfort sought to take advantage of this. In the sixth, Szymanski landed shots and tried to circle away, but he remained too close and got caught with a left hook.

Campfort couldn’t keep it up, though, and Szymanski made the adjustment he needed, sticking and moving, picking his exchanges in the eighth and the ninth, punctuating the penultimate round with a left hand that sent Campfort’s mouthpiece flying out.

Szymanski had Campfort hurt in the 10th and tried to follow up to the body, but he went low while Campfort tied up. The referee broke the fighters apart, and Szymanski landed a left hook after the break. Campfort got time to recover. Szymanski tried to hurt him again, veering low once more and taking another warning from the referee. With the round clearly won, and the fight likely won as well, Szymanski coasted for the remaining moments.

The final scorecards were comfortable. Two judges had it 99-91, while the third had it 98-92.

Szymanski, a 23-year-old from Poland, is now 16-0 with 9 KOs and has picked up experience in his past two fights against a certain level of opponent; he’d outpointed Richard Gutierrez, long past his best days, in a bout last October.

Campfort is quickly learning that he’s not at the level that he thought. He got a world title challenge last November against Jermall Charlo and was promptly taken out in four rounds. He provided a test for Szymanski but wound up suffering his second straight defeat. The 31-year-old, who fights out of Fort Lauderdale, Florida, is now 21-3 with 12 KOs.

Also on the card, Former welterweight champion Kermit Cintron (37-5-2, 28 KOs) had his second fight in the last 60 days, winning an eight round decision over Carlos Garcia (10-16-1, 8 KOs). Cintron snapped a two-year layoff in May with a decision over Eduardo Flores.
