A roundup of the past week's notable boxing results from around the world:

Saturday at Indio, Calif.

Cornelius "K9" Bundrage TKO7 Cory Spinks

Retains junior middleweight title

Records: Bundrage (32-4, 19 KOs); Spinks (39-7, 11 KOs)

Rafael's remarks: Bundrage, who earned a measure of fame as a competitor on the 2006 edition of "The Contender" reality series, went to Spinks' hometown of St. Louis in August 2010 and destroyed him in five one-sided rounds to claim a 154-pound title in an upset. Instead of doors opening for him to bigger fights in one of boxing's most lucrative divisions, promoter Don King put him on the shelf and Bundrage didn't fight for 10 months. When he finally got a fight, Bundrage had to face Sechew Powell in a mandatory defense that wound up on the undercard of an untelevised card for a paltry, five-figure purse.

Bundrage won to avenge a first-round knockout loss to Powell in 2005, but that doesn't pay the bills. Then Bundrage faced another long layoff while King either wouldn't or couldn't line up another fight for him. Nearly a year off to the day after the rematch with Powell, Bundrage was back again, in yet another mandatory defense against a guy he had already faced, Spinks. This time, however, Bundrage made a six-figure purse and headlined on Showtime after Golden Boy came to his rescue by winning a purse bid and using its considerable juice at the network to get it televised. It worked out nicely for Bundrage, 39, of Detroit, who made his second defense with another definitive knockout of Spinks.

Bundrage, the far more powerful and fresher fighter despite being four years old than Spinks, the former undisputed welterweight champion, looked like he might make it a very early night when he dropped Spinks with a clean overhand right hand with about a half-minute to go in the first round. Spinks never saw the punch coming and was a bit shaky when he got to his feet, but there wasn't enough time left for Bundrage to go get him. Spinks was still in rough shape in the second round and resorted to simply grabbing Bundrage to avoid punches, for which he was warned by referee Ray Corona. Bundrage nailed him with a lot of shots, including a left-right combination in the fourth round that seemed to almost lift Spinks off the canvas.

Although Spinks tried to box Bundrage and might have won a round or two in the middle of the fight, he looked like he had almost nothing on his punches. He seemed to have little to offer but his heart, and was finished by the seventh round when Bundrage pounded him to the mat three more times. A right hand dumped him flat on his back early in the round and his legs were gone when the fight resumed. Spinks went down again from a right hand and this time barely beat the count. Moments later, Spinks fell to the mat simply because his legs were shot, so it was ruled a slip instead of a knockdown. But Bundrage dropped him for the third time in the round when he put together a decent combination and Spinks went down again, prompting Corona to call it off at 2 minutes, 32 seconds.

By then, Bundrage probably could have blown on Spinks and he would have fallen. And it's a good thing Bundrage finished him in such a decisive manner because, stunningly, judges Gwen Adair and Robert Byrd had the audacity to actually have Spinks ahead 57-56 after the sixth round. At least judge Fernando Villarreal had Bundrage ahead 57-56, which was still too close. Thank goodness for knockouts.

Spinks, despite such a punishing loss and a 3-4 record in his past seven bouts, gave Bundrage credit for winning and said he had no plans to call it quits. He'll probably wind up fighting for way too long, just like his father, former heavyweight champion Leon Spinks (who was in his corner).

Even with the knockout win, Bundrage didn't look particularly impressive. Still, he hoped a victory might pave the way for him to land the coveted Sept. 15 fight against titleholder Saul "Canelo" Alvarez. Bundrage, who claims to be a free agent from King, almost certainly won't get the assignment against Alvarez and could instead be offered a chance to defend his belt against top contender Erislandy Lara, who won in dominant fashion on the undercard.

Gary Russell Jr. TKO3 Christopher Perez

Featherweight

Records: Russell (20-0, 12 KOs); Perez (23-3, 14 KOs)

Rafael's remarks: Russell, a 24-year-old southpaw from Capitol Heights, Md., was a 2008 U.S. Olympian and the 2011 ESPN.com prospect of the year, and although the level of his opposition has been extremely weak, he is one of the most talented young fighters in the sport. He was 6-0 in 2011 and had been on the verge of breaking out this year. But then came an unexpected seven-month layoff at a time when he should have been far more active. He was supposed to fight in February on the undercard of the Victor Ortiz-Andre Berto rematch, but the card was postponed until June 23 because of Berto's biceps injury (and later canceled after Berto's positive drug test). Golden Boy rescheduled Russell to fight in April, but that fight was canceled when Russell suffered a severe left ankle sprain in training.

Russell finally made his 2012 debut on Saturday, against the utterly obscure Perez, 23, of Mexico, and destroyed him. Perez, who went down four times, was no match for Russell, whose hand speed is absolutely ridiculous -- maybe the best boxing has seen in decades. Russell easily won the opening round and then dropped Perez in the second round with a fast left-right hook combination. Three more knockdowns followed in the third round. There was a flush left hand that put Perez down and through the ropes early in the round. Then came another knockdown on another combination Perez never saw coming. Finally, Russell landed a right-left combination to floor him again and referee Pat Russell (no relation), who had warned Perez that the fight would be over if he went down again, called it off at 1 minute, 41 seconds.

Russell smoked yet another opponent who had no prayer against him. He has all the talent and potential in the world to be on the pound-for-pound list for years to come. Now it's just a matter of him taking on at least a halfway-decent opponent. The skills and speed are second to none.

Erislandy Lara W10 Freddy Hernandez

Junior middleweight

Scores: 99-90, 98-91, 95-94

Records: Lara (17-1-1, 11 KOs); Hernandez (30-3, 20 KOs)

Rafael's remarks: Lara, 29, was a 2005 world amateur champion for Cuba before defecting and turning pro in 2008. Now based in Houston, where he trains with Ronnie Shields, Lara has become one of the best junior middleweights in the world -- and one of the most avoided fighters in any weight class. Lara was given an opportunity to face Paul Williams on HBO last July, but only because he hadn't looked good in his...
