Munguia upsets Ali to win WBO light-middleweight title
Jaime Munguia produced a stunning upset win over Sadam Ali to claim the WBO light-middleweight title Saturday.
The 21-year-old Mexican (29-0) dominated from the outset in New York before knocking out Ali (26-2) in the fourth round.
Munguia was handed the fight on two weeks' notice after Liam Smith's withdrawal due to an allergic reaction.
He made the most of his opportunity, overpowering Ali from the beginning of the fight.
Ali was floored twice in the first round and again in the second as Munguia dominated.
Munguia was in complete control and it seemed only a matter of time before he landed the decisive blow, sending Ali to the canvas once more in the fourth round to end the fight.
