With family members from Ogden cheering him on at the Salt Palace Convention Center, Diego Alvarez did something on Tuesday night that no other Utahn was able to do.

The 17-year-old boxer won a bout at the Golden Gloves National Tournament of Champions, defeating Paul Jerry of Washington, D.C., 5-0 in a first-round matchup in the 114-pound weight division.

Salt Lake City's Bladimir Estrada also stepped into the ring for the first time in the tournament, but was not as successful. The 18-year-old honors student at West High lost 5-0 to a tough Texan, Rafael Medina, at 152 lbs.

Alvarez will return on Wednesday night for a second-round bout, while Estrada's amateur career is likely over. The recipient of the Rocky Mountain franchise's Youth Development Scholarship, worth $1,500, will attend Salt Lake Community College next fall and turn pro soon.

"You win some and you lose some," said Estrada, who fell in a first-round bout at nationals for the second-straight year. "You can't win them all."

Estrada started well, and seemed to have won the first round, or at least fought Medina evenly. But the Texan got stronger as the bout wore on, while Estrada ran out of gas.

"I was never hurt or anything; he never caught me with anything solid," Estrada said. "I just wasn't as aggressive as I wanted to be. I was a little tired, a little fatigued … I didn't fight like I usually fight, but oh well."

Estrada was dealing with a sore arm when he won the Rocky Mountain regional last month in Sandy, but said that wasn't a factor on Tuesday.

"I just lost," he said. "No excuses."

As for Alvarez, who attends Two Rivers High in Ogden, he stayed aggressive all three rounds to win his nationals debut. Alvarez, who was trained by Lalo Lopez, said he has been boxing since he was 9 years old and has an 83-12 career record.

"I just threw punches the whole way through, stayed aggressive from the start to the finish," he said.

Alvarez's father, Marco, got him into boxing at a young age for self-defense reasons and the years of hard work has paid off, the teenager said.

"I'm going to try to win this," he said. "I think I got a shot."

Another Rocky Mountain boxer, Tanner Cobbs of Montana, lost a tough decision to Shawn McCalman of the Colorado-New Mexico franchise.

It was a good night for Texas, the defending team champion. Not only did the Lone Star state take the Medina-Estrada bout, it got a TKO when Gregory Dismukes floored Curtis Iverson of Chicago and the referee eventually stopped the contest.

The bout of the night was staged between James Evans Jr. of Toledo and Michael Ream of Florida at 201+ lbs. In a duel that featured three standing eight counts, two on Ream and one on Evans, the Ohioan took a 4-1 decision.

Boxing resumes on Wednesday at 6 p.m., and the event runs through Saturday. The championship bouts in all 10 weight divisions are on Saturday at 7 p.m.
