Canelo Alvarez stops Amir Khan with stunning right hand

For the better part of six rounds, Saul "Canelo" Alvarez and Amir Khan put on a delightful tactical showdown, fraught with tension and wonderfully technical. Khan, the underdog, immediately put his blistering hand speed to use with a 1-2 that got the bigger man's attention. Alvarez responded with a series of right hands to the body.

Despite the size difference, there would be no instant wipeout. Alvarez had to work for it.

The two went tit-for-tat for four even rounds, Khan's flurries against Alvarez's relentless advance. The Mexican star struggled to reach his foe's ever-moving head, but soon discovered that he couldn't miss with his right hand to the body. Khan's output visibly waned in the fifth, falling victim to Alvarez's stalking blows.

Reality ensued in the sixth.

Late in the round, Alvarez (47-1-1, 33 KO) feinted a low jab that drew Khan's left hand down, then punished that error with a missile of a straight right. Khan (31-4, 19 KO) collapsed, out on impact, and Kenny Bayless didn't even bother to count.

It was the expected outcome, honestly, but Khan deserves credit for stepping up in weight against a dangerous opponent. The real story came afterwards, when Alvarez invited Gennady Golovkin into the ring and called him out. A dejected Khan and trainer Virgil Hunter each agreed that Alvarez should face Golovkin, but time will tell if they can get their catchweight issues ironed out.

Solid fight, hell of an ending. Not a bad end to the evening.

Canadian knockout machine David Lemieux dominated as expected in the co-feature. Opponent Glen Tapia, who usually operates at super welterweight, simply could not withstand Lemieux's blistering power and speed, eventually forcing his corner to step in.

Lemieux (35-3, 32 KO) found immediate success with his left hook and never let up. Anytime Tapia (23-3, 15 KO) seemed on the verge of gaining a foothold, another concussive blow immediately yanked the rug back out from underneath him. As he tried to open up in the fourth round, Lemieux blasted him with yet another left hook that took out his legs and allowed a glancing right hand to send him down for the first time in Tapia's career.

Tapia, well-known for his durability, made it up with plenty of tie, but his corner had seen enough.

Despite his loss to Golovkin, Lemieux remains a player at 160 and his seek-and-destroy stylings always make for a great show.

Troubled prospect Frankie Gomez appeared to finally live up to his potential with a rout of Mauricio Herrera in the second televised fight. Herrera (22-6, 7 KO), a notoriously difficult out who deserved a win over Danny Garcia, had no answer for his foe's power, volume, and combination punching. Gomez (21-0, 13 KO) landed uppercuts, hooks, body shots, and straights from both stances as the Puerto Rican spoiler relentlessly plodded forward.

Gomez found considerable success in the clinch, where he forced Herrera to expose his head to vicious uppercuts. Herrera soldiered on, heedless of a steadily-worsening cut beneath his left eye, but simply didn't have the power to faze his foe. Gomez ultimately swept all three scorecards, an impressive feat considering his opponent's résumé. If he can keep his head on straight, he's definitely one to watch.

Middleweight power-puncher Curtis Stevens opened the show in tremendous fashion, blowing out previously-unbeaten Brazilian with a crushing overhand right. Stevens (28-5, 21 KO) , perhaps best known for his failed title bid against Gennady Golovkin, was much more comfortable and active than in the past, slamming home power shots while Teixeira (26-1, 22 KO) worked his southpaw jab.

Stevens rattled Teixeira with a stiff jab early in the first that set the tone. Early in the second, Teixeira attempted a long-distance uppercut that Stevens withstood and countered perfectly with a right hand. Teixeira crumpled to the mat and just could not get his wits back to the referee's satisfaction.

Stevens looks extremely dangerous under John David Jackson's tutelage. I'll certainly be tuning into his future efforts.
