A new star was created on Saturday night, as Jaime Munguia (29-0, 25 KOs) of Tijuana, Baja California, Mexico, scored an emphatic fourth-round technical knockout victory against Sadam "World Kid" Ali (26-2, 14 KOs) of Brooklyn to capture the WBO junior middleweight world title at Turning Stone Resort & Casino in Verona, New York.

Munguia was too big and powerful for Ali, sending him to the canvas several times before a left hook forced the referee to stop the fight at 1:02 of the fourth round.

Ali was not strong enough or big enough for the much larger Munguia.

The one-sided loss may send Ali back to the welterweight division.

Munguia's name first came to light a few months, when Canelo Alvarez withdrew from his planned May 5th rematch with IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin.

Golovkin's handlers attempted to secure Munguia as a replacement opponent for a showdown at the T-Mobile Arena in Las Vegas.

But the Nevada State Athletic Commission (NSAC) rejected Munguia as an opponent - questioning his experience and lack of world ranked opposition.

Golovkin would shift his return to Los Angeles and secured Vanes Martirosyan as the opponent.

Munguia's luck changed for the better - when mandatory challenger Liam Smith withdrew from his scheduled fight with Ali.

The withdrawal sent Ali's handlers in a furious search for a late replacement - and Munguia was more than happy to accept. 

"This victory is something huge for me," said Munguia.

"This is a dream come true. Every fighter dreams of this. I want to thank the Nevada Commission for making this opportunity possible as they didn't allow me to fight Gennady Golovkin. I want to show that I am ready to fight at the highest level and with the best fighters."
