HOLLYWOOD – The purpose of Sugar Ray Leonard’s glitzy charity boxing night Wednesday at the Dolby Ballroom was to raise money to fight diabetes. It also served as a showcase for some of Golden Boy Promotions’ top prospects, who weren’t charitable toward their opponents.

The most impressive performance on the four-fight card might’ve been turned in by lightweight Damon Allen, who faced the toughest test of the night. Daniel Montoya, a capable fighter from Mexico, gave Allen some resistance in the first round but was so badly beaten by the end of the third of a scheduled six-rounder that his corner stopped the fight.

Allen, a slick, athletic Philadelphian, boxed beautifully but also landed hard, accurate punches to quickly break Montoya down in the final matchup of the evening.

“I was shocked that I took out my opponent like that so quickly,” Allen said. “It felt so great to be the main event tonight. I had a lot of family that wanted to be here tonight but couldn’t. Everyone can expect to see a lot from me this year and see me fighting here in L.A. and back home on the East Coast.”

Hector Tanajara (6-0, 4 KOs) also looked formidable, attacking Mexican Francisco Medel (9-3, 5 KOs) from the opening bell with crisp, punishing shots before putting him down with a left hook to the body with about a minute to go in the opening round of a scheduled six-round lightweight bout.

Medel barely got to his feet, took a few more punches – including another to the gut – and his quick-thinking corner stopped the fight. Only 2 minutes, 26 seconds had elapsed.

“It was really great to be here in front of all these celebrities and fight,” said Tanajara, who is from San Antonio. “I try to stay busy and fight every couple of months. Everyone can expect really big things from me later this year.

“My trainer Robert (Garcia) has taught me so much, with him being a world champion and him having trained other world champions.”

Los Angeles’ Edgar Valerio (7-0, 4 KOs) had to work hard to beat quick, tricky Harold Reyes (2-5-1). Valerio had some problems with Reyes’ movement and fast hands but ultimately outworked the Puerto Rican to win a unanimous decision in a six-round featherweight bout. The scores were 58-56, 59-55 and 58-56.

And, finally, in an interesting matchup, Alexis Salazar (7-3, 3 KOs) defeated 41-year-old Mexican veteran Hector Velasquez (57-28-3, 39 KOs) by a shutout decision in a six-round middleweight bout.

Velasquez was a title contender between 126 and 135 pounds who has fought a who’s who of the best fighters in the world over the past two decades, including Manny Pacquiao, Erik Morales and Edwin Valero. That means he was fighting well above his natural weight but had a wealth of experience.

He also took the fight on short notice, which is one reason he was so heavy and certainly didn’t work in his favor against a solid young prospect like Salazar.

Still, Velasquez, as crafty as ever if a bit slower, gave Salazar some of the best work of his career. Of course, he also gets good work when he trains.

“I felt really good to fight here tonight,” said Alexis Salazar. “It’s different from what I am used to. I am used to fighting in Mexico and the fights aren’t as big like they are here. I am looking forward to fighting more in the U.S. I train in Guadalajara and have had Canelo Alvarez as a sparring partner and he’s very tough. I’m looking to learn a lot from him and bring that with me to my future fights.”
