In the night's main event, WBO world super welterweight champion Sadam Ali puts his belt on the line against undefeated Mexican Jaime Munguia, who has won 24 of his 28 professional fights by way of knockout. Munguia took the fight on short notice after Ali's original opponent Liam Smith pulled out.
At 21, Munguía (29-0, 25 KOs) became one of the youngest champions in the history of Mexican boxing.
He made the most of his opportunity, overpowering Ali from the beginning of the fight.
Ali briefly rallied, but was sent to the floor once more at the end of the second round after Munguia landed a powerful right hand, followed by another series of blows, as Ali wobbled and stumbled around.
He was fighting for his first world title and the loss ended his eight-fight win streak.
Startled but little else, Vargas hit back with some big shots of his own but came off visibly worse when a cut above his left eye started to open up... superficial damage, that's all. He scored a knockdown very quick with a combination to the head and body.
The brawl-like contest continued much into the first third of this fight and it seemed evident that Azat was aware the only way he was going to win this fight was by pushing Vargas into the unknown, the uncomfortable. Ali was caught right on the chin with a left hook.
The experienced champion had to deal with constant pressure from "Crazy A" but was rarely in trouble, easing to his third successful defence with all three judges giving it to him by comfortable margins: 118-110, 116-111 and 117-111.
