Donaire vs Nishioka results: Evgeny Gradovich wins decision over Jose Angel Beranza

Russian featherweight prospect Evgeny Gradovich stayed unbeaten tonight, defeating Mexican veteran Jose Angel Beranza over eight rounds. Official scores were 79-73, 79-73, and 80-72.

Gradovich (14-0, 7 KO), nicknamed "The Russian Mexican," was able to control the tempo throughout the fight, but Beranza (35-25-2, 27 KO) didn't make life easy in there, and continually went after Gradovich, making him work for the win.

The 26-year-old Gradovich, who now lives in North Carolina, was pretty impressive in the fight, much as he was earlier this year against Frankie Leal, though that was more one-sided and also more exciting.

This fight concludes the off-TV undercard for tonight's HBO Boxing After Dark show, and now we're just minutes away from one of the most highly-anticipated fight cards of the year. Leading us off at 10 pm will be Brandon Rios vs Mike Alvarado, followed by the main event between Nonito Donaire and Toshiaki Nishioka.

Join us shortly, with live discussion happening over here.

Donaire vs Nishioka results: Jose Benavidez Jr dominates, survives late scare

Welterweight prospect Jose Benavidez Jr survived an eighth round scare tonight after dominating opponent Pavel Miranda, winning on scores of 79-73 across the board. BLH also scored it 79-73 for Benavidez.

Benavidez (17-0, 13 KO) won the fight using his left hand almost exclusively, jabbing his way to a wide lead over seven rounds, and mixing in some beautiful combinations -- things like a jab, then a left hook, then a left uppercut, sometimes six-punch combos behind the jab, were really amazing to watch.

But as sharp as he looked tonight, he was popped with a big shot in the eighth round and provided more worries about his often-criticized defensive approach, which most observers feel is his biggest weakness by far. He did hang on and survive the round without going down, but he was on shot legs and just barely made it out. A possible knockdown was ruled a slip -- it doesn't matter much, but it could have been scored a knockdown.

So there's definitely still work to be done with the 20-year-old, that's for sure. He's getting there fast offensively, but the defense needs tuning still. Miranda (17-8-1, 8 KO) had a chance, but it came too late.

We'll be back at 10 pm ET for the HBO card, with Nonito Donaire facing Toshiaki Nishioka and Brandon Rios squaring off with Mike Alvarado.

Donaire vs Nishioka results: Javier Garcia, Jose Roman war to a technical draw

Jose Roman and Javier Garcia promised a local war, and for three rounds, they delivered just that, tearing into one another until the night's second technical draw was ruled, a result of cuts from an accidental headbutt on Garcia (that's familiar) causing a stoppage before the completion of four rounds.

Roman (14-0-1, 11 KO) was the taller man and the unbeaten fighter, but was floored in the first on a left hook from Garcia (8-2-2, 7 KO), which turned the heat up from both. In the second round, Garcia went down very hard, but managed to survive the round. Roman took the upperhand in the third frame, but it went no further than that, unfortunately.

This was a hell of an action fight and even with the non-finish, it's worth seeing just to watch these two go toe-to-toe.

Donaire vs Nishioka results: Trevor McCumby scores first round TKO over Durazo

Light heavyweight prospect Trevor McCumby stayed undefeated with a first round TKO win over Eliseo Durazo on the Donaire-Nishioka card tonight, scoring two knockdowns, the second getting the fight halted.

McCumby (7-0, 7 KO) was fighting a guy who Mike Lee faced in June of this year, and quite frankly looked far more a legit prospect than Lee did. Lee went a full six rounds with Durazo and even lost one of them, while McCumby was able to put away the chubby little dude pretty quickly. (I don't say that to be mean, but, well, look up his fights -- he's a chubby, tough little dude.)

Durazo falls to 5-4 (2 KO), losing for the fourth time in his last five outings.

The first knockdown came from a left hand, while the second and final come from a vicious chopping right. McCumby threw with intent out there, and looked like someone to keep an eye on going forward.

Donaire vs Nishioka results: Ronald Ellis stays undefeated with four-round win

Miami super middleweight prospect Ronald Ellis stayed unbeaten in his fourth pro fight tonight, outpointing Denver's Katrell Straus over four rounds. All three judges had it 40-36, with BLH scoring it 39-37 for Ellis, giving Straus a close third round.

Ellis (4-0, 3 KO) had to go the distance for the first time, and the 22-year-old closed the fight well with a big final round. Straus (2-3, 1 KO) wasn't on Ellis' skill level, but gave the youngster some valuable rounds and was tough, taking some big shots and staying up, pushing it the distance. He did the job he was signed up to do, in other words.

Ellis didn't stand out as a great prospect here, but offensively he has some skills. There is, of course, still a ton of work left to do, but the physical ability is there, and that's always necessary.

Donaire vs Nishioka results: Technical draw ruled in night's opening bout

Super featherweight prospect Saul Rodriguez of Los Angeles got the first blemish to his pro record, but it's really no blemish at all. The 19-year-old went to a technical draw with Cesar Garcia in the opening fight of the Donaire-Nishioka card Home Depot Center in Carson, California, when the fight was stopped due to cuts caused by accidental headbutts.

Rodriguez (6-0-1, 5 KO) and Garcia (2-5-2, 1 KO) were having a good little scrap before it ended after three of four scheduled rounds, when referee Pat Russell was advised by the doctor that the cuts on Garcia were too bad to continue. Under California rules, that means the fight is a technical draw, not a no-contest.
