ATLANTIC CITY - About a dozen fans showed their allegiance to Atlantic City welterweight Anthony "Juice" Young Friday night by chanting for him throughout his fight against Rafael Montalvo at Tropicana Casino and Resort.

Young (8-0, 4 KOs) gave them more reasons to cheer by registering a fourth-round TKO in their scheduled six-round bout on the Javier Fortuna-Miguel Zamudio undercard. That fight ended too late for this edition of The Press.

"Those guys are from all over South Jersey," Young said. "That's why they call me the '609 Kid.' I wanted to get an emphatic win because of my fans."

Young broke open a competitive fight early in the fourth round.

The 25-year-old caught Montalvo (2-4, 2 KOs) with an overhand right that buckled his knees along the ropes and followed up with two more punches before referee Samuel Viruet halted the fight at one minute, two seconds of the round.

Montalvo, who had never been stopped before, protested vehemently, but seemed to have trouble getting onto the stool that ringside medical personnel had brought into the ring.

"I told both guys before the fight that I wasn't going to let them take a lot of punishment," Viruet said. "(Montalvo) was defending pretty well, but then he got caught with some good shots. If I didn't stop it, he would've gotten hit with two or three more punches. I stopped it to protect him from getting seriously hurt."

Montalvo, a 22-year-old from St. Clair, Pa., entered the fight with a two-bout winning streak, and was regarded as a dangerous opponent based on his two knockout victories, including a second-round stoppage against Egg Harbor Township prospect DeCarlo Perez.

Young controlled the first two rounds behind a solid body attack, but Montalvo started to gain momentum in the third by becoming more aggressive.

He also started the fourth round strong before Young took command.

"I was there when he beat Perez and I knew he was going to be tough, so I used that as motivation in my training," Young said. "I knew his record wasn't great, but he wasn't some guy they brought in just to pad my record. He came to fight and he caught my attention with some shots. But I had hurt him a couple of times earlier in the fight and once I saw him hurt again, I put my foot on the gas."

Also on the undercard, New York lightweight Deano Burrell (7-1, 6 KOs) dropped Vernon Alston (5-5, 5 KOs), of Durham, N.C. in the sixth round en route to a TKO victory.

In the main event, former WBA interim featherweight champion Javier Fortuna (22-0, 16 KOs), from the Domincan Republic, scored a spectacular, first-round knockout over Miguel Zamudio (25-2-1, 13 KOs), of Mexico.

Fortuna dropped Zamudio in the opening seconds of the fight with an overhand left. Zamudio got up, but was soon back on the canvas from another Fortuna left.

Zamudio was unconcious when he hit the floor for several minutes before coming to as ringside medical personnel put on a neck brace. Zamudio was carried out of the ring on a stretcher and taken to AtlantiCare Regional Medical Center City Campus for tests.

In the co-feature, U.S. Virgin Islands junior-middleweight John Jackson (16-1, 14 KOs) earned an eight-round, unanimous decision over Cerresso Fort (16-1-1, 11 KOs), of St. Paul, Minn., in a duel of sluggers. Jackson, who fought in the 2008 Olympics, is the son of former junior-middleweight and middleweight champion Julian Jackson.
